Any eye docs out there? Safety of midriasis agents?

A friend of mine has asked occasionally whether dilating eyedrops,
such as used for ophthalmic exams, could be used to artificially
dilate the pupil and improve night vision. Other than completely
eliminating ability to focus closer than infinity, (almost all the
agents I have seen also paralyze the ciliary muscles, and make it
impossible to focus) I was wondering about the safety of such a
technique. This would also wreak havoc with trying to read star
charts, and possibly using fixed-focus finderscopes, and possibly
telrads. I believe the image we are looking at is located at the focal
plane, usually within the eyepiece, so close focus by the eye is
needed. This may not be a show stopper, since people continue to use
scopes after cataract surgery, so I assume one would simply have to
use the focuser to bring the image into sharp focus. However, I do
know that many agents that dilate the pupil also risk increasing
intraocular pressure, which in fact could be quite dangerous.

Am I missing something else here? Could people with low intraocular
pressure gain a few mm of extra pupil size (better living through
chemistry)? Or would risk (acute glaucomatous change, visual
blurring, or other unmentioned risks) prevent use of these agents?
I'm enough of a coward to not risk it, but I'm sure someone has tried
it, and ophthamologists or optometrists could probably answer this
question quickly and possibly definitively. Since I don't work in
those fields, I don't have the answers up my sleeve, but I'd be
interested in the information.
