What is Blue Light?

Contrary to UV light, blue light is emitted all around us, every day — both outdoors with the sun as the biggest source and even indoors through windows, and by some screens on our digital devices. Our blue light filtering glasses and computer screen glasses filter blue-violet light and preserve visual comfort. Learn how to choose the best lenses for blue light prescription glasses.

What Are Blue Light Glasses Good For?

Our blue light filtering glasses are designed to protect your eyes from UV and preserve visual comfort by filtering blue-violet light*. Our various optical solutions filter blue-violet light* while allowing blue turquoise light, which is essential to your health, to pass through.

Disclaimer: *Blue-violet light is between 400-455nm as stated by ISO TR20772-2018.

Protect Your Eyes with Blue Light Glasses for You

As you can see, the ideal choice is to choose lenses that filter out some blue-violet light and allow turquoise blue light to pass through, while having the most neutral tint possible. Your lenses can be treated to be resistant to scratches and dirt. It is important to take all these criteria into account when choosing your blue-violet light filtering glasses. All our non-prescription and prescription blue light glasses are designed to filter blue-violet light to protect your eyes.

HEV Light

So, what are we looking at? To start, the wavelength of visible light is between 380-780nm. High energy visible light (HEV) is between 380-500nm and may cause damage to your eyes. HEV light includes blue-violet light (between 400-455nm as stated by ISO TR20772-2018), which can be potentially harmful to your eyes over a cumultive period of time, and blue-turquoise light between 460-500nm, a major synchronizer of biorhythms. The most powerful source of blue-violet light is the sun, by far, even indoors through windows. Blue light filtering glasses help to preserve visual comfort.
