The so-called sun visor, as the name implies, is used to block light. People usually adjust the luminous flux by adjusting the size of the pupil under the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, many people use sun-shading glasses to block the sun to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation.
The effect of light-colored sunglasses is not as good as sun-shading mirrors, but they are rich in colors, suitable for use with various clothing, and have a strong decorative effect. Light-colored sunglasses are favored by young people because of their rich colors and diverse styles, and fashionable women love them even more. Special sunglasses have a strong function of blocking sunlight, and are often used in areas with strong sunlight such as beaches, skiing, mountaineering, golf, etc., and their anti-ultraviolet performance and other indicators are required to be high.
