Summary: Infrared Laser Safety

<WHAT line ea

   In the reference article excellent points are made about safety with
Lasers in general.  Without minimizing that, I'd like to mention that
I was under the distinct impression that Infrared light does not penetrate
the cornea (very well) and thus an Infrared Laser is much less likely
than a visible one to damage the retina.  (Maybe it will still damage the
cornea, however....)  Or is it because we are here discussing Near Infrared
light, that this point becomes moot?
