blue light hazard

potential for a photochemically induced retinal injury resulting from optical radiation exposure at wavelengths primarily between 400 nm and 500 nm

NOTE 1 This damage mechanism dominates over the thermal damage mechanism for exposure durations exceeding 10 s.

NOTE 2 The action spectrum extends into the UV-A for persons without a normal UV-A absorbing lens.
