In sunlight, people usually have to adjust the light flux by adjusting the size of the pupil, and when the intensity of light exceeds the ability of the human eye to adjust, it will cause damage to the human eye. Therefore, outdoor activities, especially in the summer, need to use the sunshade to block the sunlight, in order to reduce the fatigue caused by eye regulation or the damage caused by bright light stimulation.
