DALLAS—Essilor of America is now offering Crizal Prevencia No-Glare lenses nationwide.

“Our daily lifestyles depend more and more on computers and hand-held digital devices, so it’s no surprise that we’re seeing consumer interest in vision protection against the most dangerous wavelengths in the blue light spectrum,” said Howard Purcell, OD, FAAO, and senior VP of customer development, Essilor of America. “Patients are becoming more aware of the damage to eyes from UV light, making it important to also communicate the impact blue light emissions have on our eyes—including potential damage to retinal cells that could lead to age-related macular degeneration.”

Through a four-year partnership, Essilor and the Paris Vision Institute discovered the band [415-455 nm] within the blue-violet spectrum that is most harmful to retinal cells. This research led to the development of Crizal Prevencia lenses with Light Scan, featuring a patented technology allowing the beneficial blue light to pass through the lens while filtering out much of the harmful blue-violet and UV light.

Crizal Prevencia lenses have an E-SPF (eye sun protection factor) of 25, plus superior clarity of vision and protection against glare, scratches, smudges, dust and water, Essilor said. ■
