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. |
