Thanks to the advanced technology of lens substrates and coating, PRIVO BRF with Armor blue cut coating blocks up to 98% HEV blue light in the 415nm – 435nm range, up to 3x more than a standard clear lens.


Tired, dry eyes, eye strain, insufficient visual contrast, and headaches, all might be symptoms of long exposure to blue light. It increases the risk of macular degeneration and retinal disease. Children are also more exposed than adults to light. Because their eyes are more transparent and not fully developed, they are less protected from the dangerous effect of UV and Blue-violet light.

Decreases in melatonin cause a disruption of the sleep cycle.


Eye strain, tired eyes, dry eyes, and might be symptoms of long exposure to blue-violet light.


Part of the blue light was recently identified as harmful to our retina. It can accelerate the appearance of AMD (Age-related Macular Degeneration).


UV light is dangerous to our eyes as they are to our eyes as well. Its effect accumulates over our lifetime, accelerating eye aging and the appearance of the eye’s lens Cataract.

TRANSMATIC lenses contain photochromic dyes which cause the lens to darken when exposed to ultraviolet (UV) rays from sunlight. When the UV light diminishes, the lenses fade back to clear. As outdoor light conditions change, the level of darkness adjusts, creating just the right level of tint and allowing just the right amount of light to enter the eyes at any time. The higher the UV, the darker the lenses get. The lower the UV, the lighter the lenses get.
