In detail: do-it-yourself glasses frame repair from a real master for the site my.housecope.com.
If one or both nose pads accidentally fall off on the frame of your glasses, it doesn't matter, you can easily stick them with your own hands, without wearing them to the workshop.
To do this, you will need spring clips (mini-clamp), the other day I just bought a set of such clips at a sale for 39 rubles, and glue, I used Moment crystal, but you can also use super glue, for example.
The procedure for gluing the nose pad to the frame of the glasses is quite simple:
- Degrease the surface.
After the glue has dried, simply remove the spring clip and use the glasses as usual.
Information
Now just a huge number of people use a variety of glasses. Sometimes with glasses, there can be problems with a loose screw before the frame completely breaks. If you are experiencing similar problems, then you may need to repair your spectacle frame.
Self-repair glasses
A broken frame is a tricky breakdown and may require skill and tools to fix it. In this article, you will learn how to fix eyeglass frames with your own hands. We have tried to describe all the processes in detail. Before you start repairing an eyeglass frame, you first need to find out the reasons for its breakdown:
Simple wear of parts. Most often, the problem occurs due to wear of the parts.
Breakage due to physical strength.

Before starting repairs, examine all the elements of your glasses.
Anyone can fix most breakdowns. Depending on the problem, you may need the following tools:
Clock screwdriver;
pliers or miniature vices;
electric drill;
universal glue;
fishing line.
Study your frame before proceeding with the repair. It can be made of plastic or metal.
With prolonged use of glasses, the holes in the hinge may loosen, where the frame is attached. Sometimes you can come across a problem when the screw is lost. If you have lost a cog, then you can find it in a calculator. Most often, the cogs in it will be similar. If the thread is knocked down and a screw of the same size pops out, then a larger diameter screw should be taken to solve the problem.
To ensure greater reliability, you can simply rivet the screw. Thanks to this, it will never become loose again and will be firmly fixed. Now you know how to repair your spectacle frame if the hinges are loose. If an old frame cannot be repaired, then learn how to choose a new frame for your glasses.
This problem is most common with plastic products. The best solution to this situation is gluing. It is best to glue the arc not only in the place where the breakage occurred, but over the entire area of the arc. This will reduce the load. To make the gluing better, you can fix the arc with a fishing line while the glue dries. The glue contains elements that can damage the lens. Therefore, immediately after gluing, the lens must be cleaned of glue.
Now you know how to glue the frames of your glasses. If, after you repair the frame of the glasses with your own hands, scratches remain, then they can be repaired with the help of colorless nail polish. However, remember that it will be almost impossible to give them a presentation.
This problem most often occurs in glasses with thin metal frames. The problem can be solved in two ways. The screw that connects the two lens windows is loose. To repair the spectacle frame in this case, simply take a screwdriver and tighten the screw. In the second case, the frame could simply bend and therefore now the lens does not stand still. To align the frame, you should completely remove the lenses, take the pliers and try to align the frame. Be careful when leveling. If you overdo it, then the frame may just burst.
It's important to know! After disassembling the frame, it must be cleaned around the entire perimeter, as dirt will accumulate here.
Before you start repairing the metal frame of your glasses, you first need to prepare the tools. First you need to make a wooden jig. To avoid scratching the lenses, simply wrap them with a soft cloth. During the work, a drill may also be required. Before starting work, the place of the break on the lenses should be degreased. Some report that sandpaper can be used to sand the fracture site, but this is not recommended.
One half of the frame must be fixed on the jig with a rubber band. The second should be pressed against the first and fixed in a similar way.
Glasses must be securely fastened before drilling
Before starting drilling, make sure that all elements are securely fastened. Glue should also be applied to the fracture site. Now you need to find the optimal distance from the place in both halves of the frame and drill two through holes. Use a needle to insert a thread into one of them. Then the thread should be touched into the second hole. This procedure should be repeated several times. This will not work anymore, since the hole diameter will not allow you to push the thread through many times. The ends of the thread that remain should be parted to the sides and secured with tape.
The threads that will act as a bandage must be fastened with glue. Now you can take the remaining turns of thread that were secured with tape and attach to the main threads. Subsequently, they should also be covered with a thin layer of glue. Thanks to this winding, you can make the connection more durable. Remember to cover each layer with glue as you thread new threads. Now you know how to glue the frame of your plastic sunglasses. If you are interested, then you can read about how to wipe glasses of glasses.
Before gluing the frame of plastic glasses, it is necessary to remove the remnants of the hinge melted into the frame. If necessary, you can warm up the frame with a soldering iron and use tweezers to get the rest of the elements. Now, using copper or steel wire, you can bend the loop with an inner diameter equal to the screw fastening the hinge. After you select the desired diameter of the pliers, you can give the workpiece the shape of the letter omega.
VIDEO The next step is to put the hinge in place. You can grab your workpiece with tweezers. Now put it back in place and heat it up with a soldering iron. During the heating process, the loop will gradually deepen into the frame to the required depth. When the required depth is reached, the soldering iron can be removed. When all the installation steps are completed, you can start finishing work. All irregularities that have formed on the surface can be removed with a soldering iron.
The reasons for the discrepancy between the temples in the glasses can be quite varied. The main reason is that the holes in the hinges are simply loose. You already know how to repair glasses side dishes. We discussed this in the first paragraph. During the use of the plastic glasses, the edges may have been erased. As a result, the divergence angle can increase significantly.
VIDEO
To get rid of this problem, it is necessary to reduce the divergence angle by fusing. We have already described how to solder the metal frame of the glasses. The situation is the same with plastic frames. If necessary, you can also stick on special plastic inserts. Then they can be simply sanded. Of course, when using inserts, remember to cut them correctly. In metal glasses, the mounts could simply bend in the other direction. Take the pliers and set the fasteners in the correct position.
The temples most often break if a metal rod was used as an attachment. As a rule, such temples can be made of durable plastic. Therefore, the connection can be made using threads.
Otherwise, it will be necessary to drill a hole in each wreck, into which you later put a new metal pin. After all parts of the temples are docked, you can provide them with additional fastening using glue. As you can see, it is not difficult to repair the spectacle frame in this case.
The plastic frame may buckle. This usually occurs when exposed to high temperatures. To give them their previous shape, you should also take advantage of the increase in temperature. You can heat the glasses to the desired softness in hot water. Then, using the pliers, you can give the desired shape.
VIDEO
After the desired shape has been achieved, the product can be removed from the water and placed on a flat surface. If necessary, they can be pressed down with something heavy and left to cool completely. All deformations of metal frames can be corrected by mechanical action.
If you are using glasses with flexes, then remember that you can also repair them yourself. Repair of the flex frame of glasses with flexes can also be done using glue. If you see that the flexa is badly damaged, then you should purchase it and replace the old one. Now you know all the ways to help you repair your glasses. We hope you find this information useful and interesting.
Anyone who regularly uses glasses has come across some kind of trouble with them. From a loose screw securing the ear clip to the frame to a broken frame. And if even a child can cope with the first one, then in all other cases you will need the advice of experienced people, certain equipment and tools, as well as skills in working with this tool. What tools and equipment are required for repair, tips for repairing one or another part of the spectacle frame will be described below.
First, I would like to dwell on the causes of certain breakdowns. As a rule, there are two such reasons:
The first is the natural wear and tear of spectacle frame parts due to their long-term use.
The second is the impact on the frame of brute physical force. Dropped, and even came. Didn't notice and sat down on them. I put it in an inner pocket without a case and they pinned you in the crowd, among the passengers of public transport.
It is quite possible for a home craftsman to fix most of the breakdowns of the frame itself.
The following tools and materials may be required to repair frames:
watch screwdriver, pocket knife;
small pliers, miniature vice;
electric drill, electric soldering iron;
universal glue;
fishing line 0.3 mm.
The frame of the glasses can be made of metal or plastic. The similarities in their repair end in the restoration of the hinge's functionality. So let's start with him.
Most often, holes are loosened in the hinge, where a screw is inserted that secures the eyelet to the frame. It even happens that such a screw is lost. Such a trifle in stock can hardly be found.Although a thrifty owner can hide either its analogue from glasses that cannot be restored, or see where such cogs can be found. For example, in a broken calculator. If it turns out that the thread is knocked down, it can be restored by screwing in a screw of a slightly larger diameter. When made of a harder metal, it will repair broken threads and the hinge will hold tight.
VIDEO
For greater reliability, the end of this screw can be riveted. If it was not possible to find a suitable screw, then there is only one way out. Pick up a piece of copper or steel wire, insert it into the lugs, cut off at both ends, leaving a margin of 0.3-0.5mm and rivet both ends with a small hammer. A brass pin with a head at one end d = 0.3-0.5mm works well. Ripping the opposite end will flatten it and give that part of the hinge a neat look.
This is found in plastic frames. The problem can be solved by going the most obvious way at first glance - gluing the frame bow at the split. But! Finding super glue is hard enough. It should also be remembered that there is a large load at the point of rupture. Therefore, experts advise to reduce the load by gluing the lens around the entire perimeter of the window, before gluing the fracture site.
VIDEO
For more reliable adhesion of the frame itself and the lens with it, for a while, pull this place tightly with a harsh thread or fishing line. This method works very well if the frame is broken in two places. Before applying glue to its ends, cover the plastic lens with tape on both sides. This adhesive contains a solvent that can damage the lens. After the glue has dried, clean and grind the junction of the broken parts.
If you notice any scratches, you can cover the area with a thin coat of colorless nail polish. The joint will be reliable if the broken parts of the frame are welded by hot welding. The characteristics of the plastic make it possible to do this. But the melted joint will look sloppy. It will be very difficult to give them a presentation.
This is typical for glasses with thin metal frames. There can be two reasons for this.
Or the fastening of the screw connecting the two parts of the lens window is loose. In this case, it will be enough to tighten the screw all the way with a clock screwdriver, and flare the opposite end. Or the frame, made of thin metal, is bent and in this form is not able to hold the lens in place. Here you really need to disassemble the frame and use the lens as a blank to straighten the frame along its contour. This work must be done as carefully as possible. Metal, as a rule, is very thin, its frequent and sharp bends can lead to irreversible consequences. After that, since the lens has been removed from the frame, you can put it on glue for reliability, tighten with screws and quickly remove excess glue.
VIDEO
ATTENTION! Expert advice. After disassembling the frames, clean the inner perimeter of the lens windows from the dirt accumulated there during the use of the glasses.
Immediately before work, you need to prepare some accessories. First of all, make the so-called conductor. It is a thin wooden plate with a length slightly less than the width of the glasses and a width equal to the height of the frame. To avoid scratching the lenses, wrap a thin soft cloth around this plate. You can use a wooden ruler for this.
In the course of work, you will need a drill with a drill of the smallest possible diameter. You need to think about how to fix it still. In this case, hands will be free to perform other work. Before starting work, thoroughly degrease the place of the break on both halves of the frame.
One half of the frame is fixed to the jig with a regular rubber band. The second half is tightly pressed against the first and is fixed in exactly the same way.
Before proceeding with gluing, you need to make sure that all parts are securely fixed and will not move during operation. After that, apply glue to the fracture site, making sure that no air bubbles form. Then remove excess glue and leave the glasses alone for a while to allow the glue to dry.
The next step is to select the optimal distance in both halves of the frame near the break, drill two through holes from the upper ends of the frame. In one of them, using a needle, a regular thread 120 cm long folded in half is inserted. Then this thread is threaded into the second hole, then it is pulled back into the first. This procedure is repeated two to three times. The diameter of the drilled hole will no longer allow. The thread is pulled as tightly as possible with each turn. The remaining ends are parted in different directions and fixed with tape on the temples of the glasses. The threads that act as a bandage are coated with glue.
ATTENTION! Expert advice. Some people advise to clean up the fracture with sandpaper. This is hardly worth doing. After all, a break, not a smooth cut. The coincidence of the teeth and troughs of the fracture will contribute to a stronger connection of both parts of the frame.
Following this, one of the ends of the thread is removed from the bow of the glasses and carefully, tightly, turn to turn is wound obliquely over the gluing site. Fixing this thread at the opposite end of the bandage, fasten its turns together by filling them with glue. Next, the same operation is performed with the second end of the thread. In this case, the bevel goes in the opposite direction.
This cruciform winding makes the connection more durable. In both cases, you need to make two or three such layers of winding, not forgetting to impregnate each layer with glue.
First of all, with the help of side cutters and a file, you should get rid of the remnants of the hinge element melted into the frame. Or thoroughly warming up this piece with tweezers with a powerful soldering iron, remove it from the frame and grind the vacant place.
VIDEO
Then, from a copper or steel wire with a diameter corresponding to the size of the eyelet remaining in the temple to the hinge element, bend a loop with an inner diameter equal to the screw fastening the hinge elements. After the desired diameter of the resulting loop has been selected, use miniature pliers with round jaws to give the workpiece the look of the Greek letter omega.
The next step is to install the resulting hinge element in place. Taking the resulting workpiece with miniature tweezers, press it in place of installation and heat it with a powerful soldering iron. During the heating process, the loop will gradually deepen into the frame to the desired depth. When the desired depth is reached, the soldering iron is removed, the plastic hardens, and the loop is firmly fixed in the frame.
Finishing work remains. Irregularities formed in the process of attaching the lugs can be removed using the same soldering iron. Sand the place with fine-grained sandpaper. Shine lost after sanding can be restored with colorless nail polish.
The reasons for the discrepancy between the temples for metal and plastic eyeglass frames are different. There is only one common thing - the holes in the hinge joints are loosened after long-term operation. The elimination of these shortcomings was discussed in the first paragraph. When using glasses in a plastic frame, one of the reasons for the divergence of the temples is that the edges are erased in places of their contact with the frame. As a result, the angle of divergence of the temples exceeds the set 100 degrees.
Here you can solve the problem if you restore the erased part of one of the surfaces by fusing or gluing a thin layer of plastic on it. You can use glue, which, after drying, will acquire a certain hardness. Then carefully grind these inserts, adjusting them to the desired size in thickness.
VIDEO
Of course, when applying these inserts, you should not cut them exactly in the area.They can be adjusted at the end of the insertion work. Metal frames have different ways of attaching temples to the frame. There are those when the temple is attached to a bracket that is integral with the frame.
It so happens that, under the influence of brute force, these brackets can be bent in any direction. In this case, they can be returned to their original position using miniature pliers.
The temples break only if a metal rod is not used as a base. As a rule, such temples are made of rather thick plastic. Therefore, the broken parts can be connected using a thread band according to the method described above.
Considering the width and thickness of the temple, part of it can be grinded off with a file in order to put a bandage in the resulting groove. In this case, it will not stand out much on the surface of the temple.
Another way is to drill holes in the center of both fragments into which a metal pin 15-20 mm long can be inserted. After using this pin, both parts of the temple are docked, lubricate their junction with superglue.
The plastic frame and temples can only be bent when exposed to high temperatures. They are resilient enough to bend when subjected to force. This means that you can give them their previous shape in the same way - heat them up and bend them to their original position. You can heat to the desired softness in hot water - boiling water using a pair of pliers. The plastic from which the glasses are made lends itself well to heating and this operation is usually successful.
After the part to be repaired has warmed up enough, remove it from the water. Place the ear hook on a flat surface and press down with something heavy until it cools completely. Give the frame the desired bend and hold it in this position with your hands, too, until it is completely cooled. It can bend only at the place of the jumper between the lens windows. This is where the main effort should be made.
Deformations of metal frames and temples can be corrected by mechanical action with pliers or simply by hand.
However, in order to achieve a secure attachment, an effective adhesive mixture must be selected.
Gluing plastic glasses on your own is not as difficult as it might seem at first glance.
All the tools that are needed for repair work are likely to be easily found in the house:
Mini drill with a thin drill (0.3-0.5 mm.);
Needle;
Thread;
Degreasing agents (alcohol or nail polish remover);
Stationery rubber bands;
Textile;
Cotton swabs;
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:
Often, glasses break in half in the place where the nose bridge is located. When all the inventory is ready and you buy the necessary glue, proceed to glue the frame.
Here is an example of repairing spectacle frames using Bison Plastic glue:
Sand and sand the broken surfaces to be glued;
Degrease the surfaces to be glued with nail polish remover or alcohol;
Cut a piece of a wooden ruler so that its length is the same as the distance between the side parts of the glasses - this will fix the glasses in one position, which will increase the quality and convenience of repair;
Cover the lenses with paper to avoid scratching them;
Attach a 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 a snug fit of the two broken-off parts of the frame;
Slowly squeeze the adhesive into the seam at the fracture;
Fill the joint completely so that there are no gaps and voids;
Use a cotton swab to wipe off the remaining glue before it dries;
Leave the glasses in this position for 2 hours until the glue is completely dry;
On the nose, on both sides of the joint, make one hole with a drill;
Pull the thread around the seam through the drilled holes. To do this, use a needle. The color of the thread should be matched to the color of the frame;
Pass the thread through both holes until they are tightly filled;
Cover the holes with a lot of glue to soak the thread;
Remove the remnants of the glue mixture with a cotton swab, and cut off the excess thread;
Set your glasses aside for 24 hours to allow the glue to dry completely.

Often, problems arise due to breakage of the temple (temples).
If they broke in half, there is an effective way glue the shackle of glasses tightly :
In the middle of the ends of both broken off parts of the bow, drill one longitudinal hole;
In each broken off part of the bow, near 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;
Use a chisel to cut small grooves between the pairs of upper and lower through holes, into which you will later need to lay the wire;
Pour epoxy or acetone-containing glue into both longitudinal holes drilled in the ends of the shackle;
Insert a steel wire rod into one of the longitudinal holes so that it protrudes slightly outward;
Apply a thin layer of glue to both split ends of the temples;
Connect both broken pieces by placing one half of the bow on the rod protruding from the other half;
The joint must be tight, do not allow voids;
Wipe off excess glue with a cotton swab;
Wrap the seam with nichrome wire, pulling it through the through holes;
Pull the split parts with it to increase the adhesion strength;
Hide the protruding wire in the previously cut grooves;
Twist the ends of the wire, making a turn;
Cut off the rest of the wire with wire cutters;
Let the glasses dry for another day, after which you can continue wearing them.
It should be noted that the glue will only help with minor breakdowns. In some cases, you need to resort to more sophisticated repair methods or buy new glasses.
Glasses, which are constantly worn, most often end up in extreme conditions, and therefore sooner or later get damaged. In this case, it is customary to contact a repair shop, paying considerable sums for the restoration of the frame. But it turns out that you can repair glasses with your own hands, if you first deal with their device and study the basic methods of restoration. In some cases, you will need to solder the glasses, but often you can do even without it.
In one of them, the bow is attached by means of a conventional screw connection. A more complex design is the version in which a special spring-loaded mechanism called a flex is used for fastening.
In the simplest case, when the malfunction is associated with unscrewing the screw from the attachment point, it is enough to simply return it to its place using a clockwise screwdriver or a well-sharpened knife. No soldering is needed here.
In the presence of flexes, the repair of glasses is significantly complicated, since the fixing screw in this case passes through the movable bar, and when it falls out, it is pulled into the ear cavity.
In this case, two fastening holes, which coincide in the normal state, after this breakdown, due to the action of the spring, lose their coaxiality, so that the screw cannot be returned to its place. The only possible way out of this position is to slide the bar back into place and screw the fastening screw into the hole.
To return the bar, the easiest way is to use an awl or needle that allows you to catch on a small protrusion that extends beyond the temple of the glasses.For this operation, two hands are usually not enough, so either outside help or a small vise (clamp) will be required.
VIDEO
In the second case, the body of the temple is first clamped, after which you can try to screw the screw into place. In the case when the material behind the ears is very soft, it is advisable to lay them with a piece of leather.
If the screw is damaged or lost, it can be replaced with any suitable size and thread. If the diameter does not match, it is screwed into the fastening hole with effort, thereby cutting a new thread. You can also use a piece of copper wire of a suitable cross-section, which, after installation in the hole, is riveted from both sides.
For some glasses, the earhook (bow) breaks at the point where the hinge is attached to the flex itself, which forces you to choose one of two solutions: complete replacement or repair. Since this part can only be changed with glasses, we will consider the device of the node and the procedure for restoring it in more detail.
A possible option for its restoration is a connection in a fractured place by means of a rivet.
As such a part, a brass sewing pin with a head about a millimeter in diameter can be used, for which you need to drill holes in the parts to be joined. When marking, one of them is outlined in the center of the earhook (bow) so that it coincides with the center line of the strip fixed in the hinge. Only after attaching this part it will be possible to clearly mark, and then drill holes in both halves to be joined.
In some models of glasses, the lenses are rigidly mounted in half of the rim, and their open part is held in the frame by means of a fishing line recessed in a special groove. This way of fixing the lenses makes glasses more elegant in appearance and comfortable to wear by reducing the weight of the frame.
But all these advantages come at the cost of the inconvenience that they easily break in the event of a negligent relationship. Here, as well as when repairing a flex, the following two options are possible:
if the lens jumped out of the mount, and the fishing line remained in its place - due to its elasticity, the optical element of the glasses is easily installed in its previous position;
in a situation where the line has completely fallen off the frame, it will need to be completely replaced.
In the latter case, you should not get upset and immediately contact the workshop, since such a malfunction can be easily eliminated with your own hands. This problem can be solved with the help of a durable fishing line with a cross section of 0.8 mm, from the skein of which a piece of about ten centimeters is cut off.
After removing the old scaffold, make sure that the ends of the new workpiece easily pass into the fixing holes, and if not, then sharpen them a little (cut along the oblique line). If, in this case, the fishing line does not pass through the holes, it is necessary to expand them in some way (sometimes you even have to drill out this part of the mount).
VIDEO
After the ends are inserted into the holes, and the size is measured strictly along the length of the lens arc, you should warm up their ends with a soldering iron, then securely fix the optics in the frame. This is a case of using soldering to repair glasses.
If the frame is metal, and the metal of the lens holder has burst, then soldering can be used for repair. The holder is soldered using rosin as a flux (zinc chloride is better for stainless steel and steel), and the solder is chosen either tin-lead or in accordance with the characteristics of the metal of the frame.
It is not uncommon for glasses to break into two parts one of the arms, and the breakage occurs in the area of the joint between the metal and the plastic tip, fixed to the pin by means of a screw.In this case, of course, you can use the method of laser soldering of metals, but at home this option is difficult to implement.
It is much easier to use for this a brass plate of the corresponding shape and thickness of 1 mm, connecting both halves, ground at the point of contact.
There are two holes drilled in the cover, and there are fixing folds on each side. The size of one of the holes coincides with the relief notches in the openwork pattern of the metal part, while the second is made arbitrary. After assembling the bow into a single whole, it takes on a completely wearable look.

The arch skeleton can be repaired using the same methods as for earhooks. However, in this case, it would be wiser to purchase a new, not very expensive frame that matches the color and structure of the metal. Rearranging it instead of the old broken part will not be difficult.
The simplest solution is to glue the metal rim directly to the lenses of the glasses. In this case, the bonding area is significantly increased, which provides the necessary strength of the joint formed.
For these purposes, the well-known brand of universal glue "Contact" is optimal, the strength of which only increases over time. To prevent glue from getting on the plastic lenses, glue a strip of adhesive tape on both sides of the joint seam. If the lenses are glass, then you can do without this, since the glue from the glass is wiped off quite simply.
Soldering eyeglass frames or thermoplastic bezels requires a soldering iron or similar heating device. They are necessary to heat up the plastic in the bonding area of broken parts joined in a molten state. This is not soldering in the full sense of the word, since solder is not used here.
VIDEO
You can do without soldering devices if you use dichloroethane or benzene, which melts the plastic to the desired state at normal temperatures.
Regardless of the selected heating method, the parts of the frame softened to the required state are tightly pressed against one another and kept for some time, sufficient to obtain a reliable diffusion connection.
The restoration of parts by a laser method is carried out using a special microscope, which affects the cost of all repair operations.
This method can be soldered both in a vacuum and in the open air; Moreover, the use of fluxes in this case is not at all necessary. When soldering glasses, it is preferable to use an impulsive mode of operation of the laser device, using solders corresponding to the steel grade of the temples or rim.
VIDEO
Professionals carry out the soldering of titanium, composite and steel frames, they know how to choose the right solder. Soldering with a low-power laser can lead to the fact that parts of the glasses fall apart after a while, so the choice of the power of the device plays an important role.
In order to protect glasses from breakage, you need to adhere to the following recommendations:
it is best to wear them with a special safety cord, which prevents falling and damage to the product;
before removing clothes, do not forget to take off glasses in order to avoid their breakage;
it is better to store them in a specially designed case.

Note also that when not in use, it is advisable to fold the earhooks without leaving the glasses in a dangerous and unstable position.
