Classification of computer goggles coatings

Blue coating can filter electromagnetic waves to some extent. However, studies have shown that blue light in visible light can cause retinal damage and is the main factor of macular degeneration. Blue coated lenses are powerless to the blue light with the most energy wavelength of 380nm-450nm in the visible spectrum, and long-term exposure to blue light will cause degenerative changes in the retina.

Green coating can also filter electromagnetic waves, reduce reflection, resist strong light and increase clarity.

The yellow coating is a good coating for anti-radiation lenses. Most of the yellow coatings contain rare and precious metals, which can effectively block electromagnetic waves.

Yellow-green two-color coating is a patented technology of safe and healthy radiation protection coating. It refers to the patented technology that the outer yellow precious metal coating and the inner green anti-reflective coating are applied to the same lens. The outer golden yellow film is waterproof, antifouling, antistatic and electromagnetic radiation-proof; The inner green film blocks the stimulation of strong light and reflected light, protects the eyes and protects the skin around the eyes. Yellow-green double-color coating improves the transmittance and refractive index, and has the characteristics of anti-ultraviolet and anti-radiation. More importantly, it can filter out the ultraviolet and blue light that cause macular degeneration, and get rid of the problem that ordinary blue coatings are powerless.
