Crizal Prevencia

Block the bad light, let in the good!

Crizal Prevencia selectively filters blue-violet light for long-term eye health, improved overall well-being and enduring clarity of vision.


Good blue light VS harmful blue light

Light is fundamental for vision. It is needed for perception of the surrounding world: shapes, details and colours.

Good blue light (blue-turquoise): essential for overall well-being. It is necessary for regulation of the sleep/wake cycles, mood and cognitive performances.

Harmful blue light (blue-violet) damages retinal cells. Causing long-term damage to our eyes, it can accelerate the onset of age related Macular Degeneration (AMD).
