What are Photochromic Lenses?

Photochromic lenses are light adaptive corrective lenses that change their tint when exposed to sunlight. Photochromic lenses are activated by the sun’s UV rays, and because of this, they darken automatically when going outdoors. This provides a convenient eye care solution that reduces the need for an additional pair of corrective sunglasses.

Although photochromic lenses are a little more expensive than regular lenses, to some, their added convenience is well worth it. Whether you wear bifocals or progressive lenses, photochromic lenses are available in many different lens materials and designs. The most popular brand of photochromic lenses is called Transitions Optical. For that reason, photochromic lenses are commonly referred to as “transition lenses,” but there are many brands that provide a great selection of photochromic lenses such as: PhotoFusion, LifeRx, SunSensors, ColorMatic and others.

When exposed to sunlight, photochromic lenses generally reach a mid level tint. For many this tint is fine, but for others that have a higher sensitivity to sunlight, there are additional alternatives that provide a darker tint.

Photochromic lenses are also a great eye care option for children. They block 100 percent of harmful UV rays. Studies have shown that UV radiation is linked to cataracts later in life, so taking good eye care measures at an early age, may prevent problems later on.
