Sunglasses, also known as sun lenses, are used only for shading sun. In life, too many light sources can generate harmful light, especially sunlight; the light rays emitted from the inside of the sunlight comprise: visible light, infrared, ultraviolet, and the like. In the sunlight, the light flux is usually adjusted by adjusting the pupil size, and when the light intensity exceeds the adjusting capacity of the human eyes, the human eyes are damaged. The sunglasses can effectively filter partial light, prevent eyes of people from being burnt by strong light, and can also prevent ultraviolet rays from damaging cornea and sight line membrane, and the high-quality sunglasses can filter up to 97 percent of light entering eyes to avoid damage.
