I occasionally get involved in projects involving wood saws and drills, or even sometimes usage of metal cutting. I work in a chemistry building, although I rarely play with chemicals. My schooling has required safety glasses at times for compression/tension experiments, or other rapidly moving parts. I may have an opportunity soon to go to a gun range.
I still rarely wear my contacts, and even when I do, I go from 20/70 (uncorrected) to about 20/40, with glasses, it's 20/20. That is sufficient for point A to point B driving, but no speeding, because I can't see far enough to locate traps. It is certainly insufficient for iron sights.
I was told at one point work might pay for Rx safety glasses. I don't know if that offer still stands, but I should look into it, because of their usefulness.
