I don't quite understand what is intended by this statement in the news
"It is noteworthy that industry presently characterizes as "eye-safe"
lasers that emit at wavelengths
longer than 1300 nm. But it is such wavelengths that are proficient at
inducing damage to DNA: how safe is "eye-safe" when DNA in the eye can be
Laser radiation in the IR region of the spectrum is a potential cataract
hazard, depending on the intensity of the beam and exposure duration.
"Eye-safe" has no technical meaning as far as ANSI or IEC standards are
concerned. Classification of laser hazards depends upon more than just
Are the researchers saying that the hazard of laser induced cancer of the
cornea has to be controlled for in addition to cataracts?
