I've tried wearing safety goggles which I find impair my ability to detect nuances of color so critical to the perfect roast I don't know if it's the glare or the steam from my sweaty head or what, I just don't like 'em. I think I just learned to like 'em.
Protect your eyes...just ask they guy who has one.
3M has some great safety items...want some samples?
