Eyeglasses are some of the most important articles for people with vision errors. However, as more and more achievements are scored in the industry, many people have gradually ignored some necessary maintenance for eye wear. For example, yellow eyeglasses are some of the most popular and best articles in the market, but only few people have cared about how to keep them. Theoretically speaking, no matter how advanced the products are, no matter how fine the technique is; less maintenance and care will shorten the longevity of eyewear. Here is a simple introduction about how to prolong the longevity of yellow glasses.
Do not often bend or twist the frames. It is true that the frames 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.
Glasses cases are essential in maintaining eye wear. Many people have nurtured such habits that they seldom put glasses into cases, but in pockets or purses- they think nowadays glasses are made from durable frames and scratch-resistant lenses. These habits are really bad and wearers should try to avoid. If the glasses are used, put them into the cases.
Ultimately, eyeglasses maintenance is very important, no matter how advanced or perfect the glasses are, though like yellow glasses.
