What Are Photochromic Lenses?

More commonly, photochromic lenses from clear to tinted when exposed to sunlight, effectively allowing a single pair of eyewear to function as both your sunglasses and eyeglasses! Not only do these types of lenses help to reduce glare from the sun, they also provide 100 % UV-protection for your eyes regardless of tint whether their tinted or not.

How Do Photochromic Lenses Work?

Well for starters, since they adapt their tint based on how bright it is outside, glasses with variable tint lenses are ideal for
people who wear both glasses and sunglasses, and frequently go inside and outside. One of the main advantages of combining the two into one saves you from having to carry around two sets of glasses everywhere. That means no more trying to fit bulky glasses cases in your pocket or trying to remember the last place you stored your shades.

• INDOOR AND OUTDOOR SCENE CUT

Imported monomer makes coating photochromic lens highly sensitive. It is colorless transparent indoor and changes according to UV strength outdoor. The stronger UV color is, the darker lens color is. Light transmittance will increase quickly when coming back indoorside from outdoor activities. Free scene shift provides customers with comfortable experience.

What is blue light?

Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).
So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light.

Blue Cut Lenses

Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.
