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. Blue-light-blocking glasses reduce how much blue light from electronic devices reaches your eyes. But it's unclear how beneficial this actually is. You're probably doing it right now — looking at a computer, phone, or tablet that emits blue light.
