Fashion Black Men's Travel Metal Sunglasses UV400 Protection

In the sun, people usually have to adjust the pupil size to adjust the luminous flux. When the light intensity exceeds the ability of the human eye to adjust, it will cause harm to the human eye.
Therefore, outdoor activities, especially in summer, need to use sunshades to block sunlight to reduce fatigue caused by eye adjustment or damage caused by strong light stimulation.
