Photochromic lens with blue block function

Are photochromic lenses good for computer use? Absolutely!

Although photochromic lenses were designed for a different purpose, they do have blue light blocking capabilities.

While UV light and blue light are not the same thing, blue light can still be harmful to your eyes, especially through prolonged exposure to digital screens and direct sunlight. All invisible and partially visible light can have negative side effects to your eye health.

Photochromic lenses protect against the highest energy level on the light spectrum, which means they also protect against blue light and are great for computer use.

Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight.

The molecules responsible for causing photochromic lenses to darken are activated by the sun's ultraviolet radiation. Because UV rays penetrate clouds, photochromic lenses will darken on overcast days as well as sunny days.

Photochromic eyeglass lenses are available in nearly all lens materials and designs, including high-index lenses, bifocals and progressive lenses. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays.

A Blue cut photochromic lens can protecting your eyes from glare outdoors, photochromic lenses offer an additional important benefit — they help protect your eyes from harmful blue light.

Blue light lens can transform your day – they help to block harmful blue light from natural and artificial sources, such as your phone, laptop, tablet, and the sun. Sometimes called computer glasses, blue light glasses can reduce digital eye strain and headaches – not to mention, take you up a notch in the style stakes. With a huge selection of sophisticated and classy styles, wear Christopher Cloos blue light glasses all day, inside and out.

Product Feature

Photochromic lenses are available in nearly all lens materials and designs, including high indexes , bifocal and progressive. An added benefit of photochromic lenses is that they shield your eyes from 100 percent of the sun's harmful UVA and UVB rays.

Because a person's lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life, it's a good idea to consider photochromic lenses for children's eyewear as well as for eyeglasses for adults.

Modern photochromic lenses tend to be plastic and instead of silver chemicals they contain organic (carbon-based) molecules called naphthopyrans that react to light in a slightly different way: they subtly change their molecular structure when ultraviolet light strikes them.
