Blue Light

What is blue light?
Blue light is part of the visible light spectrum and has a short wavelength, which means it is a higher-energy wavelength. It falls in the range of 380nm-500nm on the visible light spectrum. Although blue light occurs naturally in sunlight, digital devices with illuminated screens also produce high levels.
 
What percentage of blue light do your Peepers Blue Light Focus™ Eyewear lenses filter?
Peepers blue light lenses filter more than 40% of high-energy visible (HEV) blue light in the 400-450 nanometer range.
 
What are the other benefits of blue light filtering lenses?
According to the Vision Council, approximately 80% of American adults report using digital devices for more than two hours every day. In addition to filtering more than 40% of the HEV blue light emitted from digital screens, Peepers Focus™ Eyewear also features a 7-layer anti-reflective coating to reduce glare while improving screen contrast. The lenses also provide UV400 protection, which protects you from more than 99% of UVA/UVB rays—the same level you'll find in our sunglasses.
