Crizal® Prevencia™ No-Glare lenses - Revolutionary protection for your eyes.
Light can be beneficial in your everyday life1
- Light is fundamental for vision
- Color perception, shapes and details
- Blue-Turquoise Light aids in your overall well-being
- Sleep/wake cycles, memory and basic mental functioning
But light can also be harmful to your vision and health2,3
- UV Light is not only a major risk factor for many skin diseases, but is also a risk factor for eye diseases, including cataract
- Blue-Violet Light is harmful to retinal cells and is one of the risk factors for the onset of age-related macular degeneration (AMD)
- AMD is the number one cause of severe vision loss and legal blindness in adults over 60—having a family history can increase your chances of developing AMD
- Be sure to let your eye doctor know if you have a history of AMD in your family
Blue Blocking Glasses
Crizal Prevencia is designed to selectively filter out harmful light while letting beneficial light pass through
- Crizal Prevencia is proven to deflect harmful Blue-Violet Light by 20%*4
- Crizal Prevencia has an Eye-Sun Protection Factor (E-SPF®) of 25, which means 25x times more UV protection for your eyes compared to wearing no lens at all†
Crizal Prevencia No-Glare blue light lenses work in 3 ways:
- Selectively filter out harmful light (Blue-Violet & UV)
- Allow beneficial light to pass through (visible light, including Blue-Turquoise)
- Maintain excellent transparency (clear No-Glare lens) for optimal vision at all times
Crizal provides superior clarity of vision with the most complete protection.

* 25% less light-induced retinal cell death rate versus a naked eye, with a 20% cut of Blue-Violet Light. 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 eye.
† E-SPF of 25 means the wearer is 25 times more protected than without any lens. E-SPF of 25 when Crizal is made with any lens material other than 1.5 clear plastic.
