Spectrally-weighted photochemical radiance L
a measure of the potential hazard that exists for a beam of
light to cause photochemical damage to the retina. L
the measure either for eyes in which the crystalline lens has
been removed (aphakes) and has not been replaced by a
UV-blocking lens or for eyes of very young children. L
the measure for eyes in which a crystalline lens is in place.
