Anti-glare blue cut lenses protect your eyes from the harmful effects of blue light caused by prolonged working hours on a computer, laptop or mobile. A blue light coating is a special coating that works by reflecting high-energy blue light and restricting it from entering into the eyes. This coating, or blue light filter, blocks the harmful portion of blue light and allows the healthy portion of blue light to pass through your eyeglass lenses. The Blue light filter is ideal for people who work on digital devices for prolonged hours. By restricting the blue light from entering into the eyes, it helps reduce the symptoms of eyestrain resulting from the screens of digital devices. Also, lenses with blue cut coating offer a comfortable vision and may improve visual performance in low colour contrast.
