The thing that ****s me about safety glasses, is that I am having trouble finding a pair that goes well over my regular glasses......grrr Bleach is bad, 98% sulfuric acid is worst. I be as careful as I can around the 20% H2SO4 acid bath when soaking my glassware and I still get holes in my pants and shirts, and I'm wearing a bloody lab coat!!! Just be careful with any chemicals in general, I got superglue splashed in my eyes and 6 months later I'm wearing glasses *sigh*
