Help Protect Your Eyes
From Harmful Blue Light1
with Crizal® Prevencia®
No-Glare Lenses.

Blue Light is Everywhere

From the moment we are born, our eyes are exposed to blue light from both outdoor and indoor environments. The sources of blue light are becoming more important in our day-to-day lives, and as we spend more time staring at devices in close proximity to our eyes, our exposure continues to increase.2

Use the slider to learn more about Blue Light.


What is sometimes referred to as "Beneficial Blue Light" is the Blue-Turquoise Light located on the light spectrum at the 465 to 495 nm range. It is believed to have positive effects on the body, like regulating our sleep/wake cycle, contributing to memory and cognitive performance, and enhancing mood. Blue-Turquoise Light is also essential for color perception and visual acuity.1 Crizal® Prevencia® No-Glare lenses have been designed to allow beneficial light, including Blue-Turquoise Light, to pass through.

1.Blue Light Roundtable, NYC. A report on Blue Light Hazard: New Knowledge, New Approaches to Maintaining Ocular Health, March 16, 2013.

Emerging research points to a possible link between exposure to blue light (400-500nm) and long term vision issues such as age-related macular degeneration.1 Blue-Violet Light, also known as Harmful Blue Light, is located at the 415 to 455 nm range on the light spectrum.2 Crizal® Prevencia® No-Glare lenses selectively filter up to 20% of Blue-Violet Light.
