Old(ish) clothes so if they get splashed it doesn't really matter, and although I wear glasses I don't in the darkroom - they get in the way and I am short sighted anyway. Plus with 50 years working in a darkroom I have never splashed my eyes with any chemical. I have never used acetone in the darkroom at all so that presents no risk.
My workshop is a different matter, Goggles when I am grinding metal or turning wood, Earplugs when I'm doing something noisy and gloves when I am working in the garden or dealing with bricks or cement. Just common sense and what risks I think may be present.
