Spectrally-weighted photochemical radiance L
A
and L
B
give
a measure of the potential hazard that exists for a beam of
light to cause photochemical damage to the retina. L
A
gives
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has been removed (aphakes) and has not been replaced by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
B
gi-
ves the measure for eyes in which a crystalline lens is in
place. Values of L
A
and L
B
over 80 mW / (cm
2
sr) are consi-
dered high for beams which completely fill a dilated pupil. *)
