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 eye glasses having blue light filter while working on digital devices is a must as it may help in reducing the risk of developing eye related problems. Blue light filter glasses by Optical Superstore feature a special coating that reflects harmful blue light and restricts it from passing through the lenses of your eyeglasses.
