High quality color changing lens surface, no scratches, scratches, hairiness, pitting, lens oblique to meet the light observation, high finish. There is no spot, stone, stripe, bubble, crack inside the lens, and the light is bright.
The two lenses of the color-changing lens must be the same color without difference, and the color change should be even, not several colors, no "Yin and Yang color"; A glimpse of sunlight, color change time is fast, no sunlight, fade time is fast. Poor quality lenses change color slowly and fade quickly, or change color quickly and fade slowly. The worst color-changing glasses don't change color at all.
The thickness of the two lenses should be the same, not one thick and one thin, otherwise, it will affect the vision, damage eye health. The thickness of the single piece should also be uniform, if it is a color-changing flat lens, the thickness is about 2mm, the edge is smooth.
Production Introduction
Under the sunlight, the color of the lens becomes darker and the light transmittance decreases when it is irradiated by ultraviolet and short-wave visible light. In the indoor or dark lens light transmittance increases, fade back to bright. The photochromism of lenses is automatic and reversible. Color-changing glasses can adjust the transmittance through the lens color change, so that the human eye can adapt to the changes of environmental light, reduce visual fatigue, and protect the eyes.
