How to seal plastic glasses. How to glue plastic glasses at home

Glasses are an essential item for all people with poor vision. But this household item is not always treated with care. As a result, they break, break, or lose screws. But this is not a problem, because you can glue plastic glasses at home using glue.

However, to achieve reliable fastening you need to choose an effective adhesive mixture.

What glue can be used to glue glasses - choosing equipment

Gluing plastic glasses yourself is not as difficult as it might seem at first glance.

All the tools you need to repair work, are likely to be easily found in the house:

Mini drill with a thin drill bit (0.3-0.5 mm.);

• Needle;
• Thread;
• Degreasers (alcohol or nail polish remover);
• Stationery erasers;
• Textile;
• Cotton buds;
• Ruler;
• Glue.

Not every glue is suitable for repairing broken plastic glasses.

To do this, you need to look at one of several types of glue:

• Bison Plastic. Effectively used for strong bonding of plastic glasses and a variety of household plastic items such as polycarbonate, plexiglass and PVC. It is also great for repairing plastic toys, remote controls, mobile phones, fastening of plastic auto and bicycle parts, PVC pipes. It is highly durable, waterproof, transparent after drying, and can withstand temperatures in the range from -20 to +100 degrees. Cost of a 25 ml tube: 290 rubles.
• Moment Plastic. Glues different kinds plastic (polyurethane, polystyrene, soft and hard polyvinyl chloride) with each other and with other materials. Excellent for fixing hard-to-glue plastics: ABS, polyethylene and polypropylene. It has a high gluing speed, is frost- and moisture-resistant, resistant to solvents, and provides a strong adhesive seam that is resistant to aging. Glasses repaired with this glue will last a very long time. Cost of 30 ml tube: 160 rubles.
• UHU Plast Special. It can be used to reliably glue glasses and plastic parts. Provides a strong hold on hard plastics and polystyrene, as well as plastics and other household items. Perfectly fills seams and microcracks thanks to the dispensing needle, which allows you to apply glue in the most hard to reach places. After drying it becomes transparent. Cost of 30 ml tube: 375 rubles.

How to glue glasses frames - step-by-step instructions

Often glasses break in half at the place where the nose bridge is located. When all inventory is prepared and you buy necessary glue, start gluing the frame.

Here is an example of repairing glasses frames using Bison Plastic glue:

• Use sandpaper to clean and sand the broken surfaces that need to be glued;
• Degrease the surfaces to be bonded with nail polish remover gel or alcohol;
• Cut a piece of wooden ruler so that its length is the same as the distance between the side parts of the glasses - this will allow you to fix the glasses in one position, which will improve the quality and ease of repair;
• To avoid scratches on the lenses, cover them with paper;
• Attach wooden ruler to one half of the glasses, attach them to each other with a rubber band. Do the same with the second half of the glasses, while pressing it tightly against the first half;

• Ensure that the two broken parts of the frame fit snugly;
• Slowly squeeze the glue into the seam at the fracture site;
• Fill the joint completely so that there are no gaps or voids;
• Use a cotton swab to wipe off any remaining glue before it dries;
• Leave the glasses in this position for 2 hours until the glue dries completely;
• On the nose bridge, on both sides of the joint, make one hole with a drill;
• Around the joint, pull the thread through drilled holes. To do this, use a needle. The color of the thread should match the color of the frame;
• Pass the thread through both holes until they are filled tightly;

• Cover the holes with a large amount of glue so that the thread is saturated;
• Leftovers glue mixture remove with cotton wool and cut off the excess thread;
• Set the glasses aside for a day to allow the glue to dry completely.

Gluing the temple of the glasses

Often problems arise due to a broken earpiece.

If they break in half, there is effective method glue the temple of the glasses tightly:

1. In the middle of the ends of both broken parts of the bow, drill one longitudinal hole;
2. In each broken part of the bow, next to the ends, make two through holes so that they create a square around the joint, and the longitudinal hole is in the center of this square;
3. Between the pairs of upper and lower through holes, using a chisel, cut small grooves into which you will later need to lay the wire;
4. Fill both longitudinal holes drilled at the ends of the bow with epoxy glue or glue containing acetone;
5. Insert a steel wire rod into one of the longitudinal holes so that it protrudes slightly outward;
6. Apply a thin layer of glue to both split ends of the temples;
7. Connect both broken parts by placing one half of the bow on the rod protruding from the other half;
8. The joint must be tight, do not allow voids;
9. Wipe off excess glue with a cotton swab;
10. Wrap the seam with nichrome wire, pulling it through through holes;
11. Use it to tighten the split parts to increase the bonding strength;
12. Hide the protruding wire into the previously cut grooves;
13. Twist the ends of the wire, making a turn;
14. Cut off the remaining wire with wire cutters;
15. Let the glasses dry for another day, after which you can continue wearing them.

Glasses is an optical device used for optical correction of human vision in case it deviates from the norm and protects the eyes from dangerous external influences.

Repairing glasses requires a tool that rarely anyone has at hand. If you do not have the opportunity to repair your glasses yourself, you can contact professionals who will repair them, and if repair is impossible, they will help you choose new ones.

If the screw for fastening the glass or in the hinge for fastening the temple (arm) has simply become unscrewed, then even a child can cope with such a repair; just take a watch screwdriver or a knife with a sharp end and tighten the screw without applying any force. more effort, all the way.

But if the frame of the glasses breaks at the place of the nose, or the temple breaks off at the hinge, then such a breakdown of the glasses is no longer easy to fix; repairs require tools and knowledge of technology.

In modern glasses, the temples are often attached to the hinges using flex. This mechanism is a spring that fixes the temple (arm) in a given position and allows the temples to move apart, in contrast to the standard 100˚ angle of ordinary glasses, by an angle of up to 160˚.

Frames with flexes eliminate pressure on the head when wearing glasses and distortion of the frame when removing glasses with one hand, so glasses with flexes last longer and are more comfortable to wear. But the more complex the glasses are, the more likely they are to break.

How to tighten a screw
in the hinge for fastening glasses frames with flexes

If it is not difficult to screw in a loose screw in the fastening hinge of simple glasses, then in glasses equipped with flexes it is not as simple a task as it seems at first glance. When attaching the temple, the screw passes through the movable flex bar, and if the screw is unscrewed, the flex bar is pulled into the cavity of the temple and the mounting hole in the frame does not coincide with the hole on the temple. It is impossible to tighten the screw.

When analyzing the breakdown, everything became clear; you need to pull out the flex bar and screw the screw into place. The bar can be easily pulled out using an awl or a needle if you thread it through the hole for the screw, but then there is nowhere to screw the screw. Otherwise, it seems like there’s nothing to grab onto. But if you look closely, it turns out that there is a ledge in the bar protruding from the temple, beyond which it can be pulled out. Only the problem of a lack of hands arises. A vice can serve as a third hand.

The temple is clamped into the jaws of a vice; if the material from which the temple is made is soft, then you need to place a piece of leather between the jaws of the vice. But even with the help of a vice, screwing a screw into the frame of glasses is not easy, since you have to hold the base of the frame with one hand and at the same time, with the same hand, use a small screwdriver to move the flex bar up so that the holes coincide. With your second hand you need to insert a screw into the aligned holes and screw it in. I only succeeded after a few tries.

The original screw was lost and had to be screwed in with a suitable diameter that came from a broken calculator. Before assembling the glasses, you must first tighten the new screw with force, thereby cutting a new thread. In order to prevent the screw from unscrewing again, I riveted it a little on the side where it exits the frame of the glasses.

If a suitable screw cannot be found, it can be replaced with a brass or steel rod of a suitable diameter for fixation by riveting its ends, as described below.

Repair of flex glasses frames with flex

I received a pair of glasses for repair, the temple of which broke off at the point where the hinge was attached to the flex.

The load on the junction of the temple with the flex is large and glasses can be repaired using superglue or epoxy resin would not provide a reliable connection. There's only one left mechanical method repair.

At the end of the temple of the glasses there was a hole with a rectangular groove, and the counter part of the part, which went into this hole and was fixed in the hinge of the frame, was a narrow flat steel strip about 1 mm thick. The only possible reliable method of repair was to connect the parts using a rivet.

Rivets industrial production to carry out such minor repairs can not be. But a brass sewing pin with a metal head 0.7 mm in diameter worked well as a rivet. The size of the pin determined the diameter of the holes that needed to be drilled in the parts to be joined.

Before drilling, you need to make markings. The first hole must be drilled in the earpiece (arm), at a point calculated so that it passes through the center of the strip secured in the hinge of the frame.

To do this, the earhook needs to be clamped in a vice. Between the jaws of the vice, so as not to damage the covering of the temples, place pieces of leather and use a core to mark the drilling point.

Next, you need to drill a hole in the earhook. It is difficult to drill a hole with a diameter of 0.7 mm with a powerful household drill without breaking the drill, since it is impossible to feel the pressure on the drill due to the greater mass of the drill and this will lead to inevitable breakage of the drill. For such work, you need a miniature drill, for example, like in a homemade mini drilling machine.

You also need to drill a hole in the flat plate that secures the temple to the frame hinge. Before drilling, you need to mark the drilling point. To do this, the plate is inserted all the way into the groove of the temple located at its end and in this form the assembly is clamped in a vice lined with leather. The temple of the glasses should take a position relative to the frame that corresponds to the glasses being worn on the person’s head.

The hole previously drilled in the temple will serve as a conductor; inserting a drill into it will drill a hole in the plate. You need to drill very carefully, using little force, as the drill can easily be broken.

The holes are drilled, and you can begin the final stage of repairing the glasses, connecting with rivets. The flat plate is inserted all the way into the groove of the temple, and the pin is threaded through the holes.

Using pliers, the pin on the opposite side of the head is shortened so that the protruding part is 0.2-0.3 mm high.

To complete the repair, all that remains is to flare the protruding part of the pin using a small hammer. To do this, you need to press the round head of the pin against the anvil and with light blows, changing the angle, flatten the part of the pin protruding above the temple.

If there is no small hammer, then you can flare the pin with a large hammer, striking weakly on the protrusion of the pin through the metal rod.

As you can see, the repair of the glasses is completed, the connection between the temples and the base with a rivet turned out to be neat and did not spoil the aesthetic appearance of the glasses.

While I was repairing the glasses, putting one temple in place, the second one broke. I had to repair it using the technology described above. Now the glasses will last a long time after repair, and time has confirmed this. I tested the technology for repairing glasses with rivets on several types of glasses frames; after the repair, the glasses at the junction of the temples with the console no longer broke.

Repairing the temple of glasses with a broken hinge

A neighbor approached me with a request to try to repair his favorite glasses, since a specialized workshop refused to repair him - they advised him to buy new ones.

The arm of the glasses broke at the hinge and at first glance it seemed that it was impossible to repair the glasses. But if you think about it, you can always find a way to repair it.

First you need to unscrew the self-tapping screw and glue the broken part of the loop to the earhook using Super-glue “Contact”. I often use this glue to glue any cracked or broken parts together. But in this case, the fracture area is small and the glue will not hold securely. Therefore, the parts were glued together mainly for the convenience of further repairs.

Next, a bracket was bent from a paper clip, as shown in the photograph, and, using heating with an electric soldering iron, fused in the longitudinal direction of the temple. The middle of the bracket should follow the crack line.

To ensure a secure connection, a second bracket was fused across the temple. To avoid burning your fingers and to fuse the bracket into the desired place on the earhook, it is convenient to hold it with tweezers. It takes up to a minute to warm up the brackets, there is no need to rush here. When the bracket warms up to the melting temperature of the plastic, it will easily fit into it.

After the brackets are fused into the temple, all that remains is to smooth out the protruding plastic and cut off its excess after cooling with a knife or grind it off with fine-grained sandpaper. If the bracket appears on the surface, then it can be heated again and sunk deeper.

Now the brackets are no longer visible, the resistance to breakage after reinforcement with steel brackets of the temple has become higher than before. The glasses will no longer break at this point. If desired, the joint can be polished, making it completely invisible.

The repairs have been completed and now the glasses look like new and, if treated with care, will last a long time. When I returned the glasses to my neighbor, he was very surprised that they were able to be repaired, but he doubted whether the temple would break off in this place again. After a month of wearing it, he started asking me what kind of glue I used to glue the glasses together. After all, he did not know that the bow at the site of the breakdown was reinforced with metal brackets.

Repair of the place where the temple of glasses is attached to the rim

Another pair of glasses with a broken temple went into repair. But in this case, the earhook was intact, but the place where it was attached to the headband was destroyed.

The earhook loop was made of brass so it didn't break. This failure is more likely due to a design flaw in the frames of the glasses, rather than to handling them.

The earhook loop was attached to a rectangular hole made in the frame using one self-tapping screw screwed into the metal of the loop. When wearing glasses, the screw slowly unscrewed, and the load on the plastic increased, which is why it cracked. Ultimately, the self-tapping screw was completely unscrewed and lost, causing the shackle to fall out of the mount.

There was no screw suitable for the size, so I had to use a standard M1.5. To do this, a thread was cut in the hinge bar with a tap.

The plate on the rim for securing the earhook loop had a crack. But installing a metal bracket to strengthen it was impractical, since it was necessary not only to strengthen the plate, but also to increase the support area of ​​the screw head

Therefore, a washer with a ribbed circumference was selected and fused into the plate by heating it with a soldering iron. As a result, the area of ​​support of the screw head on the plastic increased many times over, and the crack partially melted, which also increased its strength.

Next, the mating surfaces of the plates were lubricated with Super-Moment glue, the hinge plate was inserted into the square hole in the base of the glasses and the screw was tightened. At the same time, the broken fragment from the frame was also glued. It did not bear the load and therefore there was no need to strengthen its fastening with a bracket.

The next glasses were repaired with our own hands and their use for several months confirmed the reliability of the repairs performed.

Half-rim frame repair
with lens mount on fishing line

In a semi-rimless frame, the lenses are half mounted in the frame, and the rest of them are held in the frame by a fishing line, half recessed in the bevel (a groove running along the entire length of the end of the lens). Thanks to this method of attaching lenses, glasses have elegant look and less weight compared to rim frames, especially if the lenses are plastic.

But you have to pay for elegance with a more careful attitude during use, since such a frame, compared to a bezel frame, is less reliable. If you forget to take off your glasses and start to remove a piece of clothing over your head, it may well happen that the glass falls out or the fishing line jumps out of the frame, as in the photo. If the lens falls out, but the fishing line remains securely fastened in the half-rim, then due to the elasticity of the fishing line, the lens can be put back in place. If the fishing line is disconnected from the frame, you will need to replace the fishing line with a new one.

But don’t get upset and run to the workshop; such a breakdown of the semi-rimless frame of glasses is not difficult to fix with my own hands. For repairs, ten centimeters of transparent fishing line with a diameter of 0.8 mm is enough. You can ask fishermen you know for fishing line or ask at any fishing tackle store. They cut off half a meter for me as a thank you.

The first step when starting repairs is to remove the old fishing line from the frame. Usually it is enough to move the fishing line back and forth with force and it will move from the place of attachment. If its melted ends interfere, the line can be cut. It won't be needed anymore anyway.

After freeing the holes from the old fishing line, you need to check whether the fishing line purchased for repair fits well. To do this, you need to bite off one of its ends with side cutters or cut off obliquely so that the end of the fishing line becomes sharp. This will make it easier to insert it into the holes of the frame.

If the fishing line cannot be threaded through the mounting hole of the frame, it needs to be cleaned. This is best done using a mini drill with a drill bit with a diameter of 0.8 mm. But if this is not possible, then you can use a needle or a thin awl; an unbent one will also do paper clip.

The holes in the half-rim of the frame have the shape of a cone; on the lens side their diameters are 0.8 mm, and on the side outside 1.5 mm. This is clearly visible in the photograph. Thus, by melting the end of the fishing line, you can securely secure it in the frame.

First, the fishing line is threaded through the hole in the nose pad, without a lens. Next, the end of the fishing line is melted using a soldering iron and quickly, before the end of the fishing line hardens, it is pulled into the hole in the nose pad. You need to retract it slowly so that the line does not jump out of the hole.

If you have a high-power soldering iron at your disposal, you can wind several turns of any wire with a diameter of 1-2 mm, copper, aluminum or steel, around its tip. And with this improvised sting, warm up the fishing line. If you don’t have a soldering iron, you can melt the fishing line with a nail heated on a burner gas stove. To avoid getting burned, you need to hold the nail with pliers. You can use the sharp tip of a heated electric iron or, at worst, even a small flame from a lighter to melt the fishing line.

After fixing one end of the fishing line in the nose pad, the lens is inserted and the fishing line threaded into the hole on the side of the temple is stretched. Next, the fishing line is pressed with your fingers where it passes through the facet of the lens, and is cut so that its end protrudes from the hole by a couple of millimeters. Next, the lens is removed, the second end of the fishing line is melted and after cooling, its lens is installed in the half-rim.

The remains of the melted fishing line protruding from the holes of the frame must be cut off flush with a sharp knife.

The glasses have been repaired and are like new. The repair took less time than it took to read this article, which I hope was useful to you.

Repairing a broken half-rim of a glasses frame

A few years passed, and my favorite half-rim glasses on a fishing line cracked as a result of a collision with the right angle of a kitchen shelf.

As you can see in the photo, the frame broke in the glass installation area at the narrowest point. To repair it, gluing technology was used, followed by reinforcement of the fracture site with a metal bracket.

In the first step, the frame must be glued with Super-Moment glue or similar, intended for gluing plastic products. To do this, you must first apply a thin layer of glue to the inside of the rim of the frame, which is in contact with the glass along its entire length. Next, also apply a thin layer of glue to the end of the glass in contact with the frame.

After gluing, a small gap was discovered between the glass and the nose pad. To ensure reliable gluing, a small amount of soda was poured into this gap and then soaked in glue.

After such gluing, the frame received sufficient strength, but for more high strength connection, a metal bracket made from a paper clip was additionally installed.

The bracket was fused into the glasses frame using an electric soldering iron. For clarity, the photo shows the bracket not yet completely recessed into the plastic.

Ultimately, the bracket was completely recessed into the plastic of the glasses, the area was cleaned with sandpaper and polished with felt. There are practically no traces of repairs left.

In the same way, you can successfully repair the plastic temples and cracked frames where the nose rests with your own hands.

Repairing a broken plastic rim of a glasses frame

I had to repair glasses with plastic frames, in which one of the plastic glasses fell out of the rim.

Upon closer examination, it turned out that the rim at the bottom was cracked in half. This is one of the glasses breakdowns that you can fix yourself in a few minutes.

To do this, just apply Super glue to the crack and inside the rim a couple of centimeters to the sides from the crack. Next, insert the glass into the rim, squeeze it tightly and hold it there for a couple of minutes.

The rim of the glasses at the crack site does not bear any force load, and therefore there is no need for reinforcement with steel wire. Glasses repaired appearance has not changed, and now, if treated with care, they will last a long time.

Repairing metal eyeglass frames with a broken rim

They brought me glasses with metal frames with a broken rim at the bridge of my nose, which the repair shop refused to repair. The breakdown was really serious. Glue, even the strongest one, will not hold in this case, since the area of ​​the end of the rim at the fracture site was no more than a square millimeter.

I, too, immediately thought that this was a hopeless case and it was impossible to repair the glasses, but after a while I suddenly came up with an idea on how to do without welding metal. After all, you can repair the frame by gluing the broken metal frame directly to the lens of the glasses. The area of ​​the gluing surfaces will become large and, thus, sufficient strength of the frame will be ensured after the repair as a whole.

The universal super glue “Contact” is well suited for gluing frames. This adhesive is made on the basis of cyanoacrylate, has great adhesive strength and polymerizes upon contact with water in the air. The higher the air humidity, the faster the glue hardens, so you can glue even damp surfaces. The setting time of the glue, depending on air humidity, ranges from several seconds to several minutes. The glue hardens completely within a day.

By the way, not all home craftsmen know that if you need to quickly repair a crack or chip in hard materials, you can prepare homemade putty by mixing super glue with baking soda.

The lenses of the glasses were plastic, and to protect them from glue getting on the optical surface, strips of tape had to be glued on both sides around the perimeter of the lens. Cover the entire surface of the lens in one piece Scotch tape is undesirable, since after gluing it will be difficult to peel it off without damaging the optical surface of the lens. Excess tape on the ends of the lens can be easily removed using fine sandpaper.

If the lenses are made of glass, then there is no need to glue the tape. Super glue is easily softened with acetone, which is safe for glass. Therefore, to remove residual adhesive after repair from the optical surface of the lenses, it is enough to wipe them with a soft cloth soaked in this solvent.

Before gluing, you need to think through all the movements and practice installing the lens in the frame before applying glue to it. When the movements are practiced, you need to apply glue to the end of the lens, accurately insert it into place in the frame and tighten the frame ring with your fingers for a few minutes. I could not take photographs of applying the glue and installing the lens, since only a few seconds were allotted for this operation.

When the glue sets, remove the tape and tighten the frame with thread, tying it as in the photo. The glasses should be left bandaged for a day until the glue has completely hardened. If there is a gap between the rim of the frame and the lens, it is advisable to additionally fill it with super glue.

Checking the glasses frame after repair with gluing showed that it has a sufficient margin of safety for further use. The appearance of the glasses remained without visible changes.

Repairing a broken eyeglass frame temple

At the request of a friend, I had to repair glasses where one of the temples had broken in half. The breakdown occurred at the junction of its metal part with the plastic extension.

The metal part of the temple was attached to the plastic part by means of a protruding pin, which was tightly inserted into the hole in the plastic part of the temple and secured with a screw. It was not possible to remove the pin from the plastic after unscrewing the screw, since the break occurred along the line of the plastic, and it was impossible for the tool to catch on the pin. I also didn’t want to grind down the plastic to shorten the temple.

The difficulty of repairing the earhook at first glance was aggravated by the fact that metal part It was all covered in openwork holes. But as it turned out, this was a plus. To restore the integrity of the temple, a specially shaped pad was made from a sheet of brass 1 mm thick. I do not give the geometric dimensions of the pad, since all temples are different and the pad for repairing a specific glasses frame will have its own dimensions, depending on the width of the temple at the point of breakage.

As you can see from the photo, two holes were drilled in the cover and three bends were made. The bends are needed to prevent axial swing of the connected parts of the temple. The dimensions of the holes determined the finished holes in the metal and plastic parts of the temple, and were 2.5 mm and 1.5 mm in diameter, respectively.

The metal part of the temple was secured to the pad using a shortened M2.5 screw with a conical head. The screw was used as a rivet.

It was inserted from the outside of the metal part of the temple and riveted from the inside with a small hammer. To ensure that the riveted part of the screw does not protrude into the plate, the hole was pre-countersinked.

The pad was secured to the plastic part of the temple using an M1.5 screw screwed into the previously existing threaded hole in the remaining pin.

The photo shows a view of the pad after installing the screw and rivet on the inside of the temple.

And in this photo is a view from the outside of the temple after connecting its broken parts.

All that remains is to attach the earpiece to the frame of the glasses using a standard screw and the repair can be considered complete.

This is what the glasses looked like after the repair. If you don’t look closely, it’s difficult to notice the restored place on the temple, it’s not noticeable. But the earhook has become much stronger and now it will definitely never break in this place.

Repair of plastic glasses frames
with broken headband and earhook loop

Glasses with frames made of thermoplastic plastic are easier to repair, since it melts easily when heated, adheres well, and is dissolved by certain types of solvents, for example, dichloroethane or benzene.

I was faced with the repair of glasses with plastic frames, which were broken in three places at once. The right ear hook of the frame was broken off.

Also, as can be seen in the photo, part of the rim on the side where the temple was attached to the base was broken off. Apparently, the glasses were accidentally sat on or stepped on.

The repairs had to be carried out in two stages. First, using super-glue “Contact” using the technology described above, used to repair a metal frame of glasses with a broken rim at the bridge, the broken plastic part of the rim was glued to its original place.

In the glasses being repaired, the temples were equipped with flexes, which, during use, would create a large load on the glued part of the rim. Therefore, to ensure sufficient strength of the rim, two steel brackets, bent from a paper clip, were additionally installed at the gluing site, fused into the plastic.

To fuse a paper clip, you need to take it with tweezers and apply it to the place with the crack, as shown in the photo. Next, use a soldering iron tip with a power of 12-40 W to heat the bracket, lightly pressing on it from above. This usually takes a few minutes. There is no need to rush here.

When the bracket has entered the plastic a little, you can remove the tweezers and then, pressing, continue to heat the bracket until it is completely sunk into the base of the glasses.

Next, the soldering iron tip smoothes out the plastic squeezed out by the bracket so that the bracket is completely hidden. After the plastic has hardened, the resulting unevenness is ground off with a file or sandpaper, and the roughness is removed by polishing with felt. After this, you can begin repairing the hinge joint.

First, you need to remove the remaining loop with side cutters and use a file to level the surface of the junction of the temple with the base of the glasses.

You need to bend a rectangular loop from copper or steel wire ∅1-1.5 mm. The photo shows a loop made from electrical wiring wire. Copper, unlike steel, bends easily and has sufficient strength.

Based on the size of the base, the ends of the loop are shortened to the required length and moved apart. This shape of the loop will ensure its reliable fixation in the plastic case of the glasses.

Next, the eyelet is placed on a flat surface covered with a soft cloth and pressed down with a heavy object. The base is placed close to it, as in the photograph. All that remains is to fuse the homemade eyelet into the body of the base of the glasses using the technology described above for the bracket. After cooling, the hinged joint made will hold quite tightly and work well. If the plastic at the melting point loses its shine, then you can cover this place thin layer liquid transparent nail polish. Varnish is usually solvent-based, which softens the thermoplastic plastic.

As you can see in the photo, the repaired hinge joint of the glasses turned out to be quite neat.

From the outside, traces of repair of the plastic frame are practically invisible. The glasses have been repaired and are ready for further wear.

How to repair glasses
with a broken bow at the hinge point

In the Guest Book, Margarita from Rybinsk asked me the following question:
– I have such a problem, the child broke his glasses! The bow broke off at the hinge with the screw, that is, the hinge with the screw remained on the frame, and the bow was without a hole. The frame is plastic. I took my glasses to a repair shop and they said they couldn’t fix them, I had to buy new ones. Maybe you can recommend something.

My advice:
– Everything can be repaired, but the complexity of repairs and the need to purchase special tool often making repairs economically unfeasible. This is exactly your case. But since the main cost of glasses is optical glass and their installation, you can repair glasses at low cost if you buy a cheap frame, from which the arms will match your glasses in color, method of fastening and loop size. It's even better to buy the exact same frame. Switching the temples from one glasses to another is not difficult. The glasses will be like new.

Glasses are often a constant attribute modern man who has to spend a lot of time at the computer, because not everyone has the opportunity and desire to wear contact lenses. However, not only people with poor eyesight wear glasses; it's also quite stylish accessory, and sunglasses, waiting in the wings, lie on almost everyone’s shelf.

Whatever kind of glasses - for vision correction, perforated, sunglasses, decorative without lenses, expensive branded or cheap bought on the market for a hundred rubles - they tend to break. Frames usually break, but broken lenses are not uncommon. How often do we sit down on the sofa and suddenly hear an unpleasant crunch? This crunch indicates that it is time to buy new glasses.

It's a pity! Maybe it's not too late to fix everything? If, for example, you figure out what glasses are made of and how to fix them yourself?

Glasses design

The main element of any glasses is lenses made of glass or plastic. The lenses are inserted into the frame, to which using hinges temples or temples are attached. The hinge has a fixed part, fixed in the frame, and a movable part, welded to the metal core of the earhook and fixed in its plastic part. Some models use a headband or elastic band instead of temples.

The bridge between two lenses is called a "bridge", or nosepiece, and plastic or silicone pads protecting the bridge of the nose from strong pressure from the frame, - nose pads, which, like the temples, are attached to the glasses using hinges. The presence of nose pads is more typical for heavy metal glasses, while plastic glasses are quite light and do not put such pressure on the nose.

Any structural element of glasses can break, but the “bridge” and the junction of the frame with the temples (and nose pads, if any) are especially prone to breakage.

The good news is that even a child can handle this task! It is only necessary find superglue ("Moment" will do) and glossy paper, which is not much different in color from the frame (however, you can play with the contrast).

The paper needs to be cut into thin strips and carefully wrapped around the nose piece to the desired thickness, not forgetting to coat it with glue. Before applying a new layer, you need to wait until the old one dries.

The glasses are ready! Now you can safely wait until you go to a repair specialist.

Pretty too interesting way. You will need a small saucepan or bowl of boiling water and a pin.

First you need to melt the plastic, for which the ends of the “bridges” formed during the split are lowered as close as possible to boiling water. When the ends softened, you need to insert a short pin into one of them (you can “pinch off” part of the pin with wire cutters), and then put the other end on it. The resulting gap should be smoothed out by hand before the plastic hardens. Glasses are like new!

3. Professional repair of the “bridge”

This method is essentially similar to the previous one, but requires more attention, precision and diligence. In addition, you will need various tools:

In the ends formed when the frame splits, it is necessary to drill two holes with a diameter of 1.5 mm and a depth of 5 mm, then drill from above and below them through holes with a diameter of 1 mm. Use a cutter to create grooves between the top two holes as well as the bottom two holes. Pour glue into holes with a diameter of 1.5 mm and insert a steel wire 9 mm long. Grease the ends with glue and connect. Fasten the structure with nichrome wire, passed through the upper and lower holes. Fill the holes and grooves with glue, and after drying, sand them with sandpaper.

How to replace a lost screw?

1. Temporary repair of the hinge

You can make temporary repairs to the hinge, which will allow you to wait for a trip to a specialist, using a toothpick, wire, pin or nylon fishing line.

Frame and temple of glasses aligned with each other so that a hole is formed in the hinge into which a toothpick is inserted (or whatever comes to hand from the list presented). The excess part of the toothpick must be cut off, the wire must be twisted, and the nylon fishing line must be melted in the flame of a lighter or match.

2. Repair of a hinge with a flex mechanism

Flex mechanism is used length of fixation of glasses temples in a certain position - very convenient for those who have custom size heads! Unfortunately, such a wonderful device has a serious drawback: a screw that has fallen out of such a hinge is very difficult to put back in place.

The fact is that between the two parts of the hinge there is a movable bar, which, when the screw falls out, is pulled into the arch. To pull out the bar, you need to fix the bow (for example, using a vice) and, holding the frame and the bar pulled out with a needle or screwdriver with one hand, screw the screw into the hinge. It may not work out the first time, but don't give up! A few tries and you're done.

How to adjust the temples yourself?

Sometimes it happens that after wearing for a long time in a bag or a brief unfortunate contact with something heavy, the glasses do not seem to be broken, but still they are not very comfortable to wear: they put pressure on the ears, the bridge of the nose, or, conversely, they constantly dangle and slide down. The reason may lie in incorrect adjustment of the temples and nose pads.

• To check whether the nose pads are adjusted correctly, you need to place the glasses on a flat surface and compare their positions relative to each other. To change the height of the glasses, the nose pads should be moved (if the glasses need to be raised) or moved apart (if the glasses need to be lowered).
• If your glasses are too tight or loose, you need to hold the temples in place for a while. hot water or heat them with a hairdryer, and then slightly straighten them or, accordingly, bend them more strongly. You must act carefully so as not to melt the arms or break them. This method is suitable for plastic frames. Wire frames are easily bent using small pliers.

With the help of simple devices, you can successfully repair glasses that are broken inappropriately or adjust the frames for maximum comfort.

Glasses are a great thing, but we don't always treat them correctly. As a result, they break, break, or lose screws at the most inopportune moment. If your glass has let you down, show who's boss by fixing it using the following steps.

Steps

Repairing a broken nose bridge with glue and paper

Prevent future scratches. The lenses are thin and must be handled with care to prevent scratches.

• Use a glasses case. A durable, soft case will protect your glasses. Put them in a case, not a pocket, or straight into your purse.
• Wash your lenses. Clean your glasses every day with soapy water and dry them with a clean, soft cloth made for this purpose.
• Do not use inappropriate products. Do not use facial tissues or paper towels for cleaning lenses, and it is not recommended to wash with antibacterial soap. Be careful when using hairspray, perfume or nail polish remover - these products can destroy the coating on your lenses.

It is difficult for people with reduced visual acuity to do without corrective devices: glasses or contact lenses. The latter are not suitable for everyone, which is why many still use glasses. However, glasses are a rather fragile accessory that requires careful handling and proper care. Even with care, breakdowns are not uncommon. The first thought in this case is to contact a specialized workshop, but do not rush, because many of the damages can be repaired yourself. In this article we will tell you how to repair glasses at home and when minimum costs.

Causes and types of breakdowns

The main causes of glasses failure include wear and tear due to long-term use and mechanical stress. Glasses break from falls, squeezing, or rough treatment.

Most common problem is loosening or loss of frame and temple screws. Tightening the screw is usually not difficult, but how can you fix the temple of your glasses if the part is lost? Failure of the hinge mechanism is also not a rare occurrence. It occurs due to careless opening of the temples or if the glasses are accidentally sat on. The cause of breakage in metal frames is most often compression. An accessory without a case should not be carried in a pocket or bag. Plastic frames are quite fragile and often suffer from falls from heights. The reason for glass falling out is mechanical deformation of the frame, and scratches on the surface of the lenses arise from ignoring recommendations for the care and use of glasses.

The answer to the question of how to repair glasses with the above-mentioned breakdowns can be found below.

Required materials and tools

Repairing glasses will require use the following materials and tools:

• A set of watch screwdrivers or a set for repairing glasses. The screws in the glasses are tiny, and you won’t be able to pick them up with a regular screwdriver. If suitable tool If you can’t find one, you can use a thin knife, but you should be careful not to tear off the notches on the cap.
• Nippers and pliers. They will come in handy to make it easier to hold the frame and trim off excess wire.
• Scissors.
• Small hammer. This can be used to unfasten the bottom of the screw to prevent it from loosening in the future.
• Glue. The choice should be made on a fast-hardening glue suitable for gluing the frame material.
• Electric soldering iron.
• Paper clips, wire and head pins. They will be needed to strengthen damaged parts of the frame and to replace lost or broken parts of the hinge mechanism.

• Fine-grit sandpaper. Useful for polishing the restored area of ​​the frame and temple.
• Fishing line 0.3 - 0.8 mm. Needed to repair half-rim frames with broken or weakened fishing line.
• Strong thread.
• Transparent nail polish. The repaired and protected area of ​​the frame may lose its shine; nail polish will return it to its original appearance.
• Scotch. Useful to protect the lens from glue.

Replacing a lost screw

How to fix the temple of glasses if it falls off? The cause of the problem may be a loose screw holding the temple on the frame. Well, if the part was not lost, then it can be easily returned to its place by carefully tightening it with a screwdriver or knife. To prevent the problem from happening again in the future, you can rivet the bottom part of the screw with a small hammer. If you don’t have a miniature tool at hand, you can use a regular hammer and a metal rod.

However, how to fix glasses if the screw is lost? In this case, you can try replacing the screw with a new one. Kits for repairing glasses contain such parts. You can also use a screw from an old calculator or electronic watch. If the new part is slightly wider than the old screw, it doesn’t matter. Using careful force, the new thread can be cut. This method Also suitable for repairing glasses with broken threads or worn out due to long-term use of glasses. The excess length of the new screw is removed with pliers and riveted.

The question often arises: how to repair glasses at home if you don’t have a suitable screw at hand? In this case, you can replace it with a pin with a flat or small round head. The pin is inserted into the hole for fastening, the lower part is cut off and riveted.

Glasses repaired in this way do not lose functionality and will last longer. for a long time.

Replacing the screw in glasses with flex

Flexa is a movable bar that allows the temples of the glasses to open 160 degrees, unlike the conventional mechanism, where the temples open 100 degrees. Glasses with flex do not put pressure on the head, so they are more comfortable to wear. Repairing the temples of glasses with such a mechanism is not much more difficult than regular ones.

When there is no screw in the flex mechanism, the movable bar is pulled into the bow. As a result, the holes do not line up and the screw cannot be tightened. It is easy to return the bar to the required position with a needle, but then it will be inconvenient to screw in the screw. In this case, you can use a thin silk thread, threading it through the open hole. Use a thread to secure the mechanism in the open state and tighten the screw. Next the thread is cut. The remaining piece will not interfere with the functionality of the glasses.

It is even easier to make a similar repair by replacing the screw with a pin. No thread is needed, and the flex can be pushed out with the point of a pin. Next, the pin is cut and riveted. The renovated area becomes neat and inconspicuous.

Hinge mechanism failure

How to fix glasses if the hinge mechanism itself is broken? Repairs begin with careful removal of the damaged part, it is important not to damage the frame. A file is suitable for these purposes. When the surface is leveled, production of the replacement part begins. A copper wire of suitable diameter is passed through the remaining intact loop of the mechanism and bent into the shape of the Greek letter omega. Next, the parts are connected and the wire is heated using a soldering iron, gently pressing it into the softened plastic until completely immersed. Thus it turns out strong connection. When the wire has cooled, the area is sanded and leveled. You can disguise the repair with a matching nail polish.

Unfortunately, this repair method is only suitable for plastic frames.

Plastic frame repair

Many people are faced with the problem: how to repair glasses frames so that the repair is not too noticeable? The easiest way to repair frames is made of plastic. First of all, it is necessary to protect the lenses from glue. This mainly applies to polymer lenses and lenses with anti-glare coatings; glue can be easily removed from glass with solvent or nail polish remover. Scotch tape is suitable for these purposes. They paste the lens around the perimeter. It is advisable not to touch the center of the optical surface so as not to damage its properties.

The next step is to coat the end of the frame and the fracture site with glue, insert the lens and fix it tightly. The glue sets in a couple of minutes. You will need to wait about a day until it dries completely. For a tighter fit, you can wrap the glasses with strong thread. After complete drying, excess glue is removed.

When the glue has completely dried, they begin to strengthen the broken area. To do this you will need a paper clip or staple. The paper clip is bent like a staple, leaving the ends 1-2 mm long. If work is carried out with a bracket, its ends are shortened. Next, using tweezers, hold the bracket over the breakage site, heat it with a soldering iron and carefully press it into the plastic of the frame. After cooling, the area is sanded with fine-grained sandpaper and masked with nail polish.

How to fix glasses with a broken bridge?

The procedure is similar to repairing the frame. First, the fracture site is fixed with glue. To ensure that the connection is tight and does not move during the drying process, use a structure of two wooden planks and stationery erasers. After complete drying, excess glue is removed, and the fracture site is additionally strengthened with a metal bracket. Such repairs are almost invisible and do not spoil the appearance of the glasses.

Broken fishing line in a semi-rim frame

In such a frame, the lens is held on one side by the frame, and on the other by a fishing line. The glasses look sleeker and weigh less. However, this design is less durable than the classic frame version. Most frequent breakdown is a break in the fishing line holding the lens from below. Is it possible to repair glasses with such damage? As easy as pie! To repair, you will need a new fishing line of a suitable diameter and a little patience. Fishing line can be purchased at any fishing tackle store.

First you need to remove the old fishing line. This is usually easy, but if the end of the line is stuck, a needle or thin awl may come in handy. A new fishing line is inserted into the cleaned hole, its end is melted and carefully fixed into the hole. The holes for the fishing line are made cone-shaped; they are narrower on the inside than on the outside, which allows you to fix the fishing line without a protruding edge. Next, insert the lens and secure it tightly with fishing line along the bevel. The edge of the fishing line is passed into the hole, it is cut and melted, tucking the end into the cone of the hole. If the melted ends of the fishing line protrude, they are carefully trimmed with a blade. After repair, the glasses look like new.

How to repair glasses with a broken metal frame is a question that arises often, because it is difficult to do without welding. Metal frames are usually very thin, and no adhesive will hold it strong enough. In this case it will do next way.

The essence of the method is to fix the lens to the frame using glue. The lens is covered with tape around the perimeter to protect it from glue. To clean the ends of the tape, you can use fine-grained sandpaper. Glue is applied to the end of the lens and inserted into the frame, tightly fixing the structure. When the glue has set, the glasses should be wrapped with strong thread and left to dry completely.

After a day, you can remove the fixing and protective materials and clean the glasses from excess glue. If the work is done carefully, the repair will be almost invisible.

Lenses falling out of frames

The reason for lenses falling out of the frame is most often the loosening of the screw that secures the frame, or its deformation. In the first case, it is enough to tighten the screw, and in the second it is necessary to return the frame to its original shape.

WITH metal structure easiest to work with. It is enough to fix it in a vice and slowly bend it in the desired direction. To avoid damaging the frame coating, you should use a piece soft fabric or skin.

Before working with a plastic frame, it should be heated. It is best to heat it in a pan of boiling water. Hot steam will soften the plastic and make it softer and more pliable. Next, the frame is returned to its original appearance.

The reason for lenses falling out of semi-rimless frames is most often the loosening of the securing line. In this case the best solution will be replacing the fishing line with a new one.

• If you are not confident in your abilities and are afraid of irreversibly damaging the accessory, it is better to contact a workshop where you can have your glasses repaired.
• You can remove glue from glass lenses using acetone. However for polymer materials this method is destructive.
• You can cover up chips and cracks in the frame by preparing a mixture of glue and regular baking soda. This “putty” will reliably hide the defect, and after complete drying it can be sanded.
• You can disguise the traces of repairs with nail polish of a matching color. The surface will be smooth and shiny again.

Following simple rules for caring for glasses will allow them to last longer, without breakage or damage.

Glasses are a fragile thing that requires careful handling and care to avoid contamination and breakage. The most common areas that require repair are the hinge mechanism of the temples, falling lenses, and cracks in the frame.
