In ophthalmology, high-energy visible light (HEV light) is high-frequency light in the violet/blue band from 380 to 500 nm in the visible spectrum. HEV light has been implicated as a cause of age-related macular degeneration.
Some sunglasses are now designed specifically to block HEV.

Famous quotes containing the words visible and/or light:
“Make visible what, without you, might perhaps never have been seen.”
—Robert Bresson (b. 1907)
“Her mane falls wild on her forehead,
And the light breeze moves me to caress her long ear
That is delicate as the skin over a girls wrist.
Suddenly I realize
That if I stepped out of my body I would break
Into blossom.”
—James Wright (19271980)
