What is blue light?
Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).So approximately one-third of all visible light is considered high-energy visible (HEV) or "blue" light.
Blue Cut Lenses
Blue cut lenses feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses. Blue light is emitted from computer and mobile screens and long term exposure to this type of light increases the chances of retinal damage. Hence, wearing eyeglasses having blue cut lenses while working on digital devices is a must as it may help in reducing the risk of developing eye related problems.
