Sunglasses, also called sunshade mirrors, are used to shade from the sun. People in the sun usually need to adjust the size of the pupil to adjust the light flux, when the light intensity exceeds the ability of human eyes to adjust, it will cause damage to human eyes.
Therefore, in outdoor places, especially in summer, sunshade mirrors need to be used to block the sun, in order to reduce the fatigue caused by eye regulation or damage caused by strong light stimulation.
