Photochromic Sunglasses
These photochromic glasses are slightly colored, they are light gray. While keeping the transmittance, the color of the lens darkens correspondingly when it meets the sunshine, and changes obviously in the strong light. FEISEDY Photochromic lens is irradiated with ultraviolet light and short-wave visible light in sunlight, and the color becomes darker, the light transmittance is lowered; in the indoor or dark, the light transmittance of the lens is improved, and the color fading is recovered. The photochromism of the lens is automatic and reversible. The color-changing glasses can adjust the transmittance through the discoloration of the lens, so that eye can adapt to changes in the ambient light, reduce visual fatigue, and protect the eyes, keep the eyes always the most comfortable state.
