The Sunglasses: an invention created specifically to protect the eyes from ultraviolet rays, and overexposure to sunlight.
However, the sunglasses in recent times, and their purpose was passed, making the use of these a matter of fashion. In fact, especially among young people, you are literally competing to see who has the model most innovative frame and processed. In frequent, especially in summer time, it happens that the delicate frames go to break and repair (in addition to cost a lot) is very difficult in an independent manner, without the help of an expert. On the other hand, there are techniques that allow the repair of the frame, in a simple and much cheaper. In this guide I’m going to list a few, and the most common of repair sunglasses.The cyanoacrylate adhesives are a useful solution for the rapid repair of the frame. Their transparency also allows not notice even the use of such product, but still having the necessary resistance to the fixing of the part damaged, or even detached (as rod or the output of a lens). Check for cleanliness before spreading the adhesive the lens, so that it fits perfectly, and then apply the liquid and immediately after the lens, or the bar. Press in a very lightweight, and do not use too much pressure since the taking of these adhesives is almost immediate.
The major drawback of the hinges is the easing of small screws Frame. This is not unusual and happen in all frames, regardless of the thickness (although obviously it will be thicker and more durable). This phenomenon can become a nuisance, even if it is caused by the simple act of closing and opening the rods. See internetdict.com for how sunglasses are made.
When this phenomenon starts to take place and to cause the continuous loosening of the screws, which act as a pivot, the only final solution is to apply a bead of sealant locking agent. (you can easily find at auto supply stores or motorcycle, accessories and boating.)
If the closure is rather too harsh, it means that in the hinges has accumulated too much dirt, so just put a little lubricant upon them. Here you’ll find some very effective, which you can buy directly online.
Another drawback is the fact that the lens runs off from the frame, common phenomenon especially in metal frames, rather than in those in acetate and plastic. The screw on the metal is bound by the arms that often close the frame, so if this is loosened, the stranding widens and allows to escape the lens. In this case, just tighten the screws, as written above.
Another possible cause that can make the lens escape is the changed climate. The expansion between the frame (more frequent in metallic lenses) and exchange radical climate, means that the lens will magnify and then shrink, making then escape. In this case you just put a wire silicon (possibly transparent, and thin) in the throat that engages the lens, carefully spreading it with a finger, and finally apply the lens. (The help of a cutter could be of help). At this point, the resilient nature of the silicone will be able to compensate for the different expansions, even at very low temperatures.
In plastic frames instead of the lens spill can be caused by an inaccurate cut by the latter, with respect to the wearer’s shape. To solve the problem simply heat the frame with a hair dryer, until it becomes soft. Once this is done, it locks the lens in place and if necessary, further heats up with the hair dryer, modeling the plastic until it returns to its normal state of solidity, making sure to give the correct form, so that the lens does not escape again.
I hope this guide on How to Repair Sunglasses both came in handy, although the first suggestion that usually I like to give is to have a good care of the glasses. These repair methods are simple and still not quite too expensive, and there are many others that show the links that let in description in the bottom of the page.
