When i worked in a chemical factory, they convinced us that we WANTED to wear safety glasses. They had a safety video that showed a pair of safety glasses a carpenter had worn.
A nail from his nail gun had missed, bounced off a hard surface, and then STUCK in his safety lens. The lens popped out of the eyeglass frame and gave him a bruise, but it did NOT pass through his eyeball and brain.
We all wore our safety glasses after that video!
