Sunglasses Manufacturers
Sunglasses, also called sun-shading mirrors, are used for shading. People usually adjust the luminous flux by adjusting the pupil size in the sun. When the light intensity exceeds the adjustment ability of the human eyes, it will cause damage to the human eyes. Therefore, in outdoor activities, especially in summer, it is necessary to use sunglasses to block sunlight to reduce fatigue caused by eye adjustment or damage caused by strong light stimulation.
