According to research conducted by the North American Eye Care Union, the best colors for sunglasses are smoky gray and green. These colors of sunglasses can minimize the sensitivity of color. Wearing pink, yellow, orange, red, and violet sunglasses can cause eye fatigue, and under strong sunlight, the line of sight will be blurred due to fatigue. As a result of this claim, many aircraft and car drivers have switched to smoked grey and green sunglasses.

1, the color of the lens and their respective characteristics
(1) Gray film: The gray lens can absorb evenly in any chromatogram, so the viewing scene will only darken, but there will be no obvious color difference, showing a true natural feeling. It belongs to the neutral color system.
(2) The brown lens filters out a large amount of blue light, which can improve the visual contrast and sharpness, and is better in the case of severe air pollution or foggy.
(3) The green lens absorbs the light while maximizing the green light reaching the eyes, so it has a cool and comfortable feeling and is suitable for people who are prone to fatigue.
(4) The blue-gray lens is similar to the gray lens, and belongs to the neutral lens, but the color is deeper and the visible light absorption rate is higher.
(5) The surface of the mercury lens is made of a high-density mirror coating. Such lenses are more absorbed into the visible light and are suitable for outdoor sports.
(6) Yellow lenses Strictly speaking, such lenses are not sunglass lenses because they hardly reduce visible light, but in foggy and dusk moments, yellow lenses can improve contrast and provide more accurate video, so it is also called night. glass. Some young people wear yellow lenses "sunglasses" as a decoration.
(7) Light blue, light pink and other lenses are also more decorative than practical lenses.
2, the color of the lens
The color depth of the lens only affects the visible light absorption performance, and has nothing to do with the UV resistance. Because the ultraviolet light is invisible light, the UV resistance is determined by the lens material, not the color depth. Some resin sheets are colorless and transparent, but still 100% UV resistant.
Some of the sunglasses are progressive resin lenses, which are shallow and shallow, until they are close to colorless. These sunglasses are worn outdoors and can block the sunlight from the upper front. They can still be seen indoors or in the car. If the light color progressive color is worn for middle-aged women, it will have a good decorative effect.
