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:

  1. Selectively filter out harmful light (Blue-Violet & UV)
  2. Allow beneficial light to pass through (visible light, including Blue-Turquoise)
  3. Maintain excellent transparency (clear No-Glare lens) for optimal vision at all times

Crizal provides superior clarity of vision with the most complete protection.
