Blue light, part of the visible light spectrum with wavelengths between 380-500 nanometers (nm), is emitted not only by the sun but also by artificial light sources such as LEDs, computers, some smart phones, and tablets. While a particular range of this light [465-495 nm] is beneficial and aids in the function of the sleep/wake cycle, memory, and cognitive performance, there is a specific band of blue light that is found to have a harmful effect on the retina and is a risk factor for the onset of age-related macular degeneration (AMD).

“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, O.D., F.A.A.O., and senior vice president 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 precise band [415-455 nm] within the Blue-Violet spectrum that is most harmful to retinal cells. This innovative research led to the development of Crizal Prevencia lenses with Light Scan™, featuring a breakthrough, patented technology allowing the beneficial blue light to pass through the lens while filtering out much of the harmful Blue-Violet light.

“Blue light is part of the visible spectrum of light, and it’s everywhere – outdoors in any weather and indoors through digital devices and compact fluorescent light bulbs,” said Dr. Gabriel Keita, associate director technical marketing, Essilor of America. “Our studies show that a certain band of blue light increases the rate of retinal cell death, so a new lens technology was needed to selectively filter the bad light out while allowing beneficial light through the lens.” Crizal Prevencia lenses deflect 20 percent of harmful Blue-Violet light and these lenses are shown to lead to a 25 percent decline in porcine retinal cell death.

Crizal Prevencia lenses also offer an E-SPF® of 25. The eye sun protection factor of 25 means the wearers’ eyes are 25 times more protected against UV rays than wearing no lenses at all, and offer superior clarity of vision with the most complete protection against glare, scratches, smudges, dust
