Goggles coating classification
The blue coating can filter out electromagnetic waves to a certain extent. However, studies have shown that blue light in visible light can cause retinal damage, which is a major factor in macular degeneration. Blue coated lenses are powerless against blue light with the most energetic wavelength of 380nm-450nm in the visible light spectrum. Long-term exposure to blue light will cause degenerative changes in the retina.
The green coating also has a certain effect of filtering out electromagnetic waves, at the same time it can reduce reflection, resist glare, and increase clarity.
Yellow coating is one of the better coatings for anti-radiation lenses. Most of the yellow coatings contain rare and precious metal components, which can effectively block electromagnetic waves.
Yellow-green two-color coating is a patented technology for safe, healthy and anti-radiation coating. It refers to the patented technology in which the outer layer of yellow rare precious metal coating and the inner layer of green anti-reflective coating are applied to the same lens. The outer layer of golden yellow film is waterproof, anti-fouling, anti-static, and anti-electromagnetic radiation; the inner layer of green film blocks strong light and reflected light stimulation, nourishes the eyes and cares for the skin around the eyes.
