Computer screens, smartphones, tablets, fluorescent bulbs—blue light is all around, and the sun is actually the largest source of it. Some of it is helpful, like Beneficial Blue Light (which is blue turquoise and defined as 465-495 nm on the light spectrum), which helps regulate the sleep cycle, your mood, and cognitive performances.
However, long-term and continuous exposure to Harmful Blue Light (or blue-violet light) can contribute to long-term damage of your eyes. Those at highest risk are people with a family history or exhibiting signs of AMD, and working professionals, children, teens, and gamers.
Crizal Prevencia lenses reduce exposure to Harmful Blue Light while still allowing beneficial blue-turquoise light to pass through. Plus, they provide all the benefits of no-glare lenses. Help protect your eyes from blue-violet light with Crizal Prevencia lenses.
