Crizal® Prevencia®

Crizal® Prevencia®

Crizal Prevencia enhances lens solution by selectively filtering harmful UV and Blue-Violet light while letting essential light pass through.

  • Filters blue-violet light(1)
  • Repels dust particles for clearer vision and easy to clean lenses
  • Repels bothersome smudges for visual clarity and easy to clean lenses
  • Scratch resistant : ensuring clear vision, guaranteed for 2 years*
  • Lenses will reflect UVA and UVB light
  • Repels water droplets so lenses stay clear
  • Glare reduction : less reflections for clarity of vision and improved aesthetics

Harmful light protection

Most of the visible light spectrum is essential for our vision and overall well-being. However, the part of the light spectrum made up of UV and blue-violet light can be the cause of premature eye ageing. Crizal Prevencia provides protection against harmful light whilst preserving your patients overall well-being.

E-SPF 35

Crizal Prevencia is rated E-SPF 35, which is the optimal UV protection on a clear lens(2).

Embedded lens protection with Eye Protect System

Crizal Prevencia powered by Eye Protect System protects wearers eyes by absorbing selected blue-violet light waves into the material of the lens. Eye Protect System and Lightscan offers a maximized protection, filtering on average 30% of blue-violet light (1.59 index lens).

Lens protection

Water Repellency
Water Repellency

Water Repellency

Microscopic gaps in the coating are filled with Hydrophobic (water repellent) molecules. Therefore, smoothing the surface of the lens, which allows water droplets to roll from the lens surface without leaving a trace.

Dust Repellency
Dust Repellency

Dust Repellency

An anti-static layer prevents positive dust particles sitting on the lens

Scratch Resistance
Scratch Resistance

Scratch Resistance

Lenses are protected by a scratch resistant booster, a nano millimetre layer located behind the AR layer. The scratch resistant booster layer is designed to gradually increases in hardness.

Smudge Repellency
Smudge Repellency

Smudge Repellency

Smudges appear on lenses due to uneven nano molecules found on the surface of coatings. By smoothing fluorinated molecules into a consistent pattern Crizal Sapphire UV coatings offer a superior smudge repellence.

Glare resistance
Glare resistance

Glare resistance

A micro-layer found on both the front and back surface of the lens minimises reflections and allows more light to pass through the lens, removing unwanted reflection for wearers.

(1) Crizal Prevencia blocks 20% of the harmful Blue-Violet light, reducing retinal cell death by 25%. The Blue-Violet light cut may slightly differ depending on lens material. In vitro experiments conducted by Essilor and Paris Vision Institute,Retinal Pigment Epithelium cells were exposed to Blue-Violet light, reproducing the physiological exposure to sunlight of the 40-year-old human eye.

(2) The E-SPF® index depends on the lens material itself and the coating. E-SPF® is a global index rating the overall UV protection of a lens. E-SPF® was developed by Essilor International and endorsed by 3rd party experts. Lens performance only. The E-SPF® index excludes direct eye exposure that depends on external factors (wearer’s morphology, frame shape, position of wear). E-SPF®=10 for Crizal® Prevencia lenses with Essilor Orma 1.5®.
