Lenses that change color depending on conditions are broadly termed as photochromic lenses. They are clear in normal circumstances but when exposed to UV light they automatically become tinted and double as sunglasses. These lenses have come as a blessing for people who wear normal eye glass lenses because until this creation they were not able to protect themselves from the harmful radiations of the sun. These lenses help correct vision and protect your eyes at the same time.

About Photochromic Lenses

In terms of construction, these lenses are normally crafted from stiffmaterials such as polycarbonate, glass and other kinds of plastic. These materials are then embedded with millions of silver halides, which is responsible for the shading or tinting effect.Out of all the silver halides, silver chloride is the most used chemical.

When these particles are exposed to visible light, they develop a transparent shade. When brought under the sun, on the other hand, these chemicals go through a process where they change in shape and take some of the visible light from the environment.As a result, the lenses change into darker color. By eliminating strong sun exposure, the process is reversed and hence, all kinds of artificial lights can once again pass through.
