Product Description
The color lenses
Color changing lens, also known as "photosensitive lens". The glass lens is added with silver halide, but at present the mainstream is resin discoloration lens, in the acrylic resin lens with the addition of Pyrex ring and other chemicals, so that the original transparent and colorless lens, in the event of strong light irradiation, will become colored lens, to do protection, so it is suitable for indoor and outdoor use at the same time.
Color changing lens is made of optical glass containing silver halide microcrystal. According to the principle of reversible reaction of light color tautomery, it can quickly darken under sunlight and ultraviolet radiation, completely absorb ultraviolet light, and show neutral absorption to visible light. Back to the dark, can quickly restore colorless transparent.
Bifocal lens can be used to correct both far and near vision, mainly for presbyopia. The general distribution of bifocal lens is: the upper part of the lens is to see the distance, the lower part of the lens is used to watch the use of the near point, as for the size of the near norm, the nature of the near work to set.

What Is Blue Light?
Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.
Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy.
