K: Lens coating
With the popularization of electronic products, modern people's vision is getting worse, myopia is getting younger and younger, presbyopia is getting younger and younger, not to mention all kinds of eye diseases, people who wear glasses have multiples. Soaring upwards.
Generally, lens coatings include green film, gold film, magenta film, blue film, yellow-green film and so on.
The blue film has better radiation resistance and abrasion resistance. However, the light transmittance is not as good as the green film. The light transmittance of the green film is better. But the wear resistance is not as good as the blue film.
Since the surface of the anti-radiation lens is plated with a layer of blue anti-radiation film, pick up the glasses and shake the lens left and right, there will be some blue color on the surface.
1. Add hard film. It uses silicon oxide hardening technology on the surface of the lens to make its wear resistance close to that of glass. 1. Add hard film. It uses silicon oxide hardening technology on the surface of the lens to make its wear resistance close to that of glass.
2. Anti-fouling film. The anti-fouling film is mainly made of fluoride, which can cover the porous anti-reflection film, and can reduce the contact area of water and oil with the lens, so that oil and water droplets are not easy to adhere to the surface of the lens, so it is also called waterproof film .
3. Anti-radiation film. Anti-radiation substance is a metal compound that forms a barrier on the surface of the lens. According to the principle of electromagnetic interference shielding, a special coating process is used to coat the surface of the lens with a conductive film, which can reflect and absorb low-frequency radiation and microwave radiation, avoid potential eye heating caused by low-frequency radiation, and prevent visual fatigue.
4. Anti-UV film. Can block harmful ultraviolet rays in the sun.
