Poor lens conditions
In addition to helping you live a normal life, glasses also protect you from sunlight, rain, water vapor, oil, smoke... No matter how good the lens is, it will still turn yellow due to aging, scratches, and coating peeling off, longer transition time in photochromic lens, etc. These bad lens conditions will affect vision, causing eye fatigue, dry eyes, eye astringency and other symptoms.
1. Lens yellowing / Aging
All transparent lens will turn yellow under the influence of ultraviolet rays or oxidation. If you have used a transparent phone case, you must have felt the yellowing effect. Basically all brands of lenses will turn yellow due to aging or oxidation, but the yellowing speed will be different among different brands. Yellowing of the lens will affect the original optical performance and vision. (Attention! The lens will not have the anti-blue light function due to yellowing.)
2. Coating peeling off
The coating of the eyeglass lens will expand and fall off due to exposure to high temperature or chemicals. Exposing the glasses to the sun, or contacting the lens with high-concentration detergent, styling spray, hair wax when repairing the hairstyle, etc., will directly damage the coating. Some friends often need to work in places full of corrosive chemicals (for example: decoration sites), and the coating of their glasses will quickly be corroded and peeled off. Optical lenses and sunglasses will also have coating peeling off.
3. Coating oxidation
In addition to the effect of oxidation, the lens will turn yellow, and it will also react with the lens coating. A tart of "smudges" that cannot be erased will appear on the lens, which affects the optical performance of the lens and affects vision.
4. Scratches
In daily life, collisions are inevitable, leaving scratches on the lenses. The longer you use a pair of glasses, the more scratches you will get, which will eventually affect your eyesight.
What should I do when these conditions occurs?
Some people teach to use soda powder or toothpaste to scrub the scratched spectacle lenses, saying that the scratches can be repaired. In fact, these methods will brush away the entire coating on the lens, and the scratches will disappear, but the original optical performance of the lens will also be destroyed.
If your glasses have the above conditions, replacing them with new lenses is the most direct and effective solution. We provide different kinds of high-quality eyeglass lens options to meet your different needs.
