Problems With Determining
Safe Limits
Since you have likely only received the standard single
(1) pair of eyeballs and replacement isn't yet feasible
(or covered by major health insurance plans!), trying
to figure out if your laser is a hazard to vision by
staring into its beam is a really really bad idea. Many
factors can result in it being way to late before you
discover that your vision has been harmed.
Note that even a wavelength considered eye-safe like
1,500 nm (1.5 um) is only safe in the sense that this
light won't penetrate to the back of the eye and be
focused on the retina. A high enough power density can
still obliterate the cornea and/or lens!
There are a variety of problems with doing experiments
to determine safe levels of optical radiation incident
on the eye. Here are some:
- Subjects are generally not aware of any retinal
damage until they notice that parts of the visual
field of one eye are blind. The visual system does
a good job of providing us with the illusion of perfect
vision, in spite of deficits. There is little or no
pain in most instances.
- There are individual differences in tolerance.
- Absorption of energy varies with wavelength.
- The blink reflex comes into play for visible sources.
