Danger of really bright flash lighting on people

[8x10 user]

In addition to UV we should all watch infrared exposure. That stuff causes cataracts.

8x10,

Yes, but actually, lots of forms of radiation are known to be a cause:

Basically, keep exposure of all wavelengths to a minimum when reasonable to do so!

I rarely go outside without sunglasses, even on cloudy days. No harm to do so, might help in the long run.

Have models wear really dark sunglasses, with eyes closed.... Or use (faster) film.
Don't forget to compensate for all that bellows extension.

I'm doing the same thing, f32, but using HP5. I test on myself.

I have video LED lights that are painful at those distances. NG.

I use 2 Einsteins.

Actually I find a 19" lens way too short and use 25 or 30" lenses for 1/1.

When I find an affordable 35 or 40" lens I will go to that.

If you are asking the question and are a "bit worried" I think you already know the answer.

You have absolutely no right to assault your models/subjects.

Given that you're aware of the hazard, your actions could be considered criminal negligence.

I'm serious as a heart attack.

I'm missing some information here.

Why is it necessary to use so much light and/or why is it necessary to use such slow materials?

I'm currently working with 3 asa direct positive Paper negatives on 8x10 doing head shots at 1:1 I need as much light as I can get I can get a good exposure with flash of F32 with a 10,000 Joule strobe "fish fryer" just above the lens about 2' from the sitter but I'm a bit worried that this may have some long term effect on people

I understand your problem, but I absolutely don't understand why you need to position your light at that point. That's a "mugshot" position. When you need that much power, place the lights at an angle from the eyes. There's lots of good lighting that doesn't use a dead-on beam in the face.

What can happen? Permanent eye damage. And that opens you up to criminal charges or a law suit.

What is that song by Smash Mouth?

"You might as well be walkin' on the Sun".

I'm just glad the OP at least asked for other opinions, surely he is getting an idea of how incredibly unproductive and flat out dangerous this is...10k right smack in the eyes of innocent victims....wow....
