High energy visible light

In ophthalmology, high energy visible light (HEV light) is high frequency light in the violet/blue band from 380 nm to 530 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.[1]
