Blue Light Control
Blue light is part of the visible light spectrum and is emitted by the sun. Some portions of blue light can be beneficial and help regulate our bodies’ internal biological clocks. However, blue light can have a harmful impact on the eyes. Recent studies cited by the American Macular Degeneration Foundation suggest that “the blue end of the light spectrum may also contribute to retinal damage and possibly lead to age-related macular degeneration.”
Since some forms of blue light are necessary, NASTEK™ ZAIO lens coatings selectively block only the harmful portions of blue light, while allowing beneficial blue light to pass through, making the good rays enhance your vision by letting you see through the reflected colors that occur when light moves through air.
NASTEK™ ZAIO lenses block 98.9% of harmful blue light while safely enhancing your vision and visual clarity.
