Between sunlight, fluorescent bulbs, and the many screens we look at throughout the day, blue light is all around. While Beneficial Blue Light (or blue-turquoise light) can help regulate sleep cycles and aid in cognitive performance, Harmful Blue Light (or blue-violet light) can contribute to long-term damage of the eyes.
Enter Crizal® Prevencia®, the first preventive lens to offer selective filtering of blue-violet light, reducing exposure to Harmful Blue Light while still allowing Beneficial Blue Light to pass through.
Crizal Prevencia lenses are the result of years of research in collaboration with the Vision Institute in Paris.
By gathering expertise in the areas of cellular biology, physics, and photometry, this research led to the identification of a precise spectrum of light wavelengths that are potentially toxic to retinal cells.
Based on this discovery, we developed the first clear no-glare lenses to selectively filter blue-violet light and contribute to reducing its potentially harmful effects on the eye.
