1. The lenses of sunglasses need to be replaced regularly. Exposure to sunlight for a long time will reduce the anti-ultraviolet ability, degrade the lens function of your sunglasses, and the lenses may become lighter, discolored, and brittle. If it is not replaced for a long time, it is easy to cause corneal damage and vision problems.

2. How often do people change their sunglasses?
The longer sunglasses are worn, the older the lens will be, and the film of the lens will also be oxidized. The"shelf life"of a pair of sunglasses is about 2 years. After"expiration", sunglasses are likely to lose their role of eye protection.

3. Is the darker the color of the solar lens, the better the effect of blocking ultraviolet rays?
No. The function of the lens to block ultraviolet rays is that during the manufacturing process, the lens can absorb harmful rays below 400nm, such as ultraviolet rays, which has nothing to do with the color depth of the film.
