If things go on like this, we will find that our lenses have obvious scratches. After most people find scratches on their glasses, they choose to ignore them and continue to wear them. In fact, this is the wrong approach! The rough surface of the lens will not only affect the appearance, but also be directly related to the health of vision.

Many people just wipe their glasses with paper towels or lens cloth as soon as they get dirty. Even if they are not wiped clean, the lenses will be scratched and scratched in the long run. As the number of scratches increases, the lenses will become easier and easier to clean. flowers, optical performance is reduced.
- Lens quality
Whether the lens is prone to scratching has a lot to do with the quality of the lens, that is, the coating of the lens. Today’s lenses are all coated. The better the quality of the coating, the less likely the lens is to stain.

Take off your glasses and put them on the table. Be sure to avoid the lenses coming into contact with the table, which may cause scratches due to contact between the lenses and the table.
What impact does scratches on spectacle lenses have on glasses?

2. After the lens is scratched, it is particularly easy to cause the lens to peel off, which will lead to inaccurate prescription; and the peeled off lens will affect the protective function of the lens, such as anti-blue light and ultraviolet protection functions, which cannot block harmful light from entering the eyes.

Lens care methods and suggestions
Rinse with clean water
Turn on the faucet and rinse the lenses with running water. If the lenses are dirty, you can use lens washing water or apply diluted dish soap to clean the lenses. After cleaning, take out the glasses and use a lens cloth to absorb the water. Be careful, you must blot them dry!
Use mirror boxes more often

When storing, please avoid contact with corrosive items such as insect repellent, toilet cleaning products, cosmetics, hair spray, medicines, etc. Otherwise, the lenses and frames will cause deterioration, deterioration, and discoloration.
Proper placement of glasses
When you temporarily place your glasses, it is best to place them with the convex side facing up. If you put the convex side down, it is likely to scratch and grind the lens. Do not place them in places exposed to direct sunlight or high temperatures such as the front window of the cab. High temperatures can easily cause the overall distortion and deformation of the glasses or cracks in the surface film.
According to some research data, the service life of consumers’ glasses is relatively concentrated between 6 months and 1.5 years. Therefore, we recommend that everyone replace their glasses in time to ensure the use experience and avoid affecting eye health.
