The difference between CB coated lens and non-coated lens:

1, abrasion resistance

CB coated lenses are electrostatically charged, easy to attract dust, easy to scratch the lens, not strong abrasion resistance, but non-CB coated lenses have strong abrasion resistance.

2, radiation protection

CB coated lenses have better radiation protection than non-coated lenses.

3. Technology

CB coated spectacle lens is a new technology that uses optical thin film and vacuum to coat a layer of substance on the surface of the lens to improve the ability of the lens to reflect light and to enhance or reduce light transmission.

The advantages of CB coating:

CB coated glasses can reduce the reflected light on the lens surface, see clearly, reduce the specular reflection light, increase the light transmittance, also solve the problem of wearing glasses under strong light, and increase the beauty.

CB coated glasses can prevent damage to eyesight caused by ultraviolet, infrared and X-rays. Wearing coated glasses is not easy to fatigue. The eyesight of the staff in front of the screen can be protected.

If ordinary lenses can be seen clearly, there is no need to add film. If you want to add, the resin lens can be added with anti-reflective film or hard film. Glass lenses generally only add anti-reflective film.
