What Blue Cut Lenses Do to Protect Our Eyes?
The blue cut filter coating in Blue Lenses cut down the harmful UV rays completely along with a major portion of HEV blue light, protecting our eyes and the body from potential danger. These lenses offer sharper vision and reduce the symptoms of eyestrain that are caused by a prolonged computer exposure. Also, the contrast is improved when this special blue coating reduces screen brightness so that our eyes face minimum stress when exposed to blue light.
