Many eye health experts recommend sunglasses to protect your eyes from harmful UV radiation. Lenses with UV protection may offer greater protection because they allow the eyes to be exposed to more light. This lead to greater constriction of the pupil which lets less light enter the eyes. It is also beneficial to wear anti-glare lenses while working on computer screens for long periods of time. These lenses will restrict the blue light from entering the eye and thus protecting the retina from getting damaged.
