Among them, ultraviolet rays will cause serious damage to human skin, eyes, etc.; IR infrared rays in the light released by the sun will cause damage to the body if exposed to the sun for a long time. UVB has serious effects on vision and can burn the skin. Most of the corners of your eyes absorb this UVB light, so be sure to block this light source.
