All of these effects can be produced at light intensities way, way below
the level that produces any permanent damage to the retina. Though I'm
no expert on this subject, I have also been told that sustained exposure
to this kind of illumination in a situation where you can't just "turn
it off" and where the light levels, although below permanent damage, are
well above what leads to you to blink, and especially if they occur in
stressful situations with demanding performance requirements, can
rapidly lead to various kinds of psychological distress.

Did an "expert" tell you this?

My final (and excessively lengthy) sentence above is a summary of what I
recall hearing as a participant in a meeting where a group of civilian
laser experts and U.S. Air Force personnel discussed the military uses
of laser dazzling techniques against pilots in hostile situations
(including mention of some real-world examples where this technique had
been employed).

This was some time back, and the discussion of the "psychological
distress" aspects was, as I best recall, brief with no detailed examples
being presented, which is why I started this particular sentence with a
disclaimer.

If you in turn have evidence to contradict this, or to demonstrate that
I've made errors in this particular sentence, I'd be glad to hear it,
and I suspect others on this NG might be interested also.
