Sunglasses for shading. People usually need to adjust the pupil size to adjust the luminous flux in the sunlight. When the light intensity exceeds the eye adjustment ability, it will cause harm to the eye.

Therefore, in outdoor activities, especially in summer, it is necessary to use sunshade glasses to block the sun, so as to reduce the fatigue caused by eye adjustment or damage caused by strong light stimulation.
