High-energy visible light

From Wikipedia, the free encyclopedia

In ophthalmology, high-energy visible light (HEV light) is high-frequency light in the violet/blue band from 380 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]
