Sunglasses

In the sun, people usually 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, in outdoor activities, especially in the summer, sunshades are needed to block the sunlight to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. Sunglasses can block unpleasant glare and protect your eyes from UV rays. Damaged by ultraviolet rays. All of this is due to the metal powder filter, which "selects" the light as it enters. Colored glasses selectively absorb some of the bands that make up the sun's rays because they rely on very fine metal powders. In fact, when light hits the lens, the light is diminished based on the so-called "destructive interference" process.
