Blue light is part of the visible light spectrum. It comes primarily from the sun, as well as artificial light sources like digital screens and florescent lights. This type of light gets absorbed deep in the eye, making it potentially damaging to long term vision.
Research has shown that long-term, cumulative exposure to blue-violet light can be harmful to retinal cells. This kind of exposure is one of many risk factors, such as age, genetics, diet, lifestyle, and occupation, that may contribute to age-related macular degeneration.
There are lenses that help block blue-violet light. Our lenses selectively filter at least 20% of Harmful Blue Light. Harmful Blue Light is the blue-violet wavelengths between 415-455 nm on the light spectrum believed most toxic to retinal cells*
Crizal Prevencia lenses help protect your eyes from harmful blue-violet light in everyday surroundings including sunlight, indoor lighting, and most digital screens.Learn more at crizalusa.com
