Why do we wear glasses after a period of time will feel less clear and bright when first wearing? In addition to natural aging, lenses will also be worn and scratched in the process of daily use, so how do these scratches come about? Today, let's talk about what scratches the lens? And how to avoid lens damage? In fact, most of the scratches on the lens are caused by improper cleaning. Here we introduce several commonly used methods to clean the lens. We can compare with which one you are?
Method 1: ① take off the glasses ② pull up the bottom of the clothes ③ breathe and wipe the glasses ④ put on the glasses
Method two: ① take off the glasses ② take out a tissue ③ wipe the glasses vigorously ④ put on the glasses
The above two methods are common ways to clean glasses in daily life, but these are not recommended, let us unlock the correct way to clean glasses!
(1) Remove the glasses. (2) Open the faucet and rinse the lenses with running water. If the lenses are dirty, you can also apply diluted detergent to clean the lenses ③ After rinsing, take out the glasses and dry them with a cloth. ④ Put on the glasses
See here you should understand, in fact, most of the lens damage is caused by improper use. Rinsing with water removes tiny particles from the surface of the lens, reducing the abrasion caused by particles rubbing against the lens.
In addition, some people will feel that the lens is too dirty or in order to achieve the purpose of "disinfection", used to wipe the lens with alcohol, in fact, this method is not desirable, it is likely to be in the short term the lens film corrosion, resulting in lens film.
"Delicate" lens is not strong acid strong alkali corrosive liquid stimulation. At present, some glasses cleaning wipes on the market are also more and more common, in order to facilitate the use of many people will choose, but most of these wipes contain alcohol, long time use will have certain damage to the lens film layer. It is recommended to use it properly. If conditions permit, it is recommended to wash the lens with water. If there is too much grease in the lens, you can dilute it with detergent and clean the lens.
Of course, in addition to cleaning the lens should pay attention to, choose a wear resistant lens is also very important, different manufacturers of coating technology, technology, the quality of the film itself will affect the wear resistance of the lens, here is to prompt you to choose the regular manufacturer of qualified lenses, improve the service life of the lens.
So the question is, at what point does lens wear signal the need for lens replacement? For example, if the scratches are single or multiple scratches but only appear on the periphery of the lens, not close to the optical center, then the impact is not great, if you do not have high visual requirements, you do not need to replace.
But if it is visible to the naked eye scratches or scratches just in the optical center, through the lens vision blurred unclear occlusion, it is necessary to replace the lens in time. Another is that much more special number of small scratches, uniform, and even has caused the lens to take off the membrane, membrane layer cracking, the scratches will cause diopter number change, light transmittance, film function is lost, causing poor vision correction, see things not clear like the mist, this kind of situation is also need to be replaced in a timely manner.
