MODEL : S221216 Dark blue square lens black frame optical sunglasses

Sunglasses, also known as sunshade mirrors, are used for sunshade. People usually rely on adjusting the pupil size to adjust the luminous flux in the sun. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use sunshade mirrors to block the sun, so as to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation.
