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 Light¹ (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.²
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.
¹ Harmful Blue Light is the blue-violet wavelengths found between 415–455nm on the light spectrum believed most toxic to retinal cells. Harmful Blue Light protection only available with Crizal Prevencia. Crizal Prevencia lenses block up to 20% of Harmful Blue Light.

Phototoxic Action Spectrum on a Retinal Pigment Epithelium Model of Age-Related Macular Degeneration Exposed to Sunlight Normalized Conditions. PLoS ONE 8(8): e71398. doi:10.1371/journal.pone.0071398 (August 23, 2013). Identified Harmful Blue Light through in vitro experiment on swine retinal cells, where the most toxic wavelengths are high energy visible light falling between 415-455nm on the light spectrum (blue-violet light).
³ Crizal Prevencia offers optimal UV protection, on all lens materials except 1.50 clear plastic. The higher the E-SPF® index, the greater the level of UV protection provided by the lens. E-SPF is an index rating the overall UV protection of a lens. E-SPF was developed by Essilor International and endorsed by third party experts. The E-SPF index relates to lens performance only and excludes direct eye exposure that depends on external factors (wearer’s morphology, frame shape, position of wear.
Features:
- Blue-Light Filtering – Crizal® Prevencia™ Lens doesn’t cut out all blue light like cheap Chinese Lenses. It’s Blue light filter technology, filters out 80% harmful blue light and let 20% essential blue light to pass.
- Repels Dust – Its anti-static properties catch less dust, easy to clean features ensures clean vision
- Smudge resistant – Repels annoying smudges.
- Glare Reduction – Aesthetically please and improved visual clarity.
- Scratch-resistant – Ensures longevity and clear vision.
- Water repellent – Clear lenses in all weathers, repels water droplet faster
- UV protection – Protects eyesight against harmful UV Ray, indoor and outdoor
- Aesthetic Qualities– Lenses look invisible to others
Crizal® Prevencia® is the first preventive lens offering selective protection from blue-violet light and UV rays. It aims at protecting wearers’ 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 expertise 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*. They also preserve the eye’s overall well-being by letting essential blue-turquoise light pass through.
