WHAT IS BLUE LIGHT?
Blue light is part of visible and close to UV on the light spectrum

Following a research program conducted in partnership with the Vision Institute in France, Crizal® Prevencia® is a category of preventive lenses offering a complete protection against harmful effects of blue-violet light.

UV and blue-violet light are present everywhere: outdoors due to the sun and indoors due to artificial light and electronic devices such as cell phones, tablets, and laptop computers. As most people are at risk of overexposure to harmful light in their day-to-day activities, Crizal® Prevencia® aims to offer a solution to improve eye protection.

Crizal® Prevencia® is the first preventive lens offering selective protection from blue-violet light and UV rays. It aims at protecting wearer's eyes from harmful light everyday.

Crizal® Prevencia® lenses are the result of several years of research in collaboration with the Vision Institute in Paris, France. By gathering knowledge in the areas of cellular biology, physics and photometry, this research led to the identification of a precise spectrum of light wavelengths toxic to retinal cells. Based on this discovery, we developed the first clear lenses that selectively filter blue-violet light and contribute to preventing its harmful effects on the eye.

Crizal® Prevencia® lenses selectively filter out harmful blue-violet light, up to 25% of the identified blue-violet light. They also preserve the eye's overall well-being by letting essential blue-turquoise light pass through.
