Do not often bend or twist the frames. It is true that the frames iGenics of many yellow glasses are made from twistable or bendable materials, like titanium, memory plastic and so on. Theses materials can ensure the frames will rebound to their original shapes after bending. However, no matter how excellent the materials are, over-bending will doubtless lead to some problems on the joining part, or namely the knuckles of the frames. Doing so will make the frame loose on and on and ultimately shorten the longevity of the glasses.
Keep eyeglasses from heat or extreme temperature. Though glass is still one of the most important materials employed to make yellow eye wear, more high-tech plastic lenses are used. Glass lenses will not react though under heat, but plastic lenses will melt when the temperature around is too high. Therefore, wearers are suggested to pick off the glasses when they are playing or sitting around bonfire. In so doing, wearers can not only have their eyes protected, but also prolong the life of the glasses.
While cleaning, do not rub the lenses with paper. Most of the yellow glasses are scratch-resistant by adding a special coating on the lenses. And some people may easily come to such recognition that the lenses will never be scratched. This is not completely true. Scratch-resistance mainly refers to prevent occasional, not frequent scratch on the lenses. Therefore, paper is not allowed to clean the lenses, mainly because the fiber in the paper will cause great damage onto the lenses.
