Introduction
Overview
Overview
In ophthalmology, high energy visible light (HEV light) is high frequency light from 380Â nm to 530Â nm in the visible spectrum.[1] HEV light has been implicated as a cause of age-related macular degeneration.[2][3]
Some sunglasses are now designed specifically to block HEV.
