I know Im probably gonna get hammered for this, as Im sure EVERYONE reading this wears em all the time while cleaning, but i got a painful introduction into why Safety glasses should be worn during cleaning. I had taken my bolt carrier group into my station for cleaning while on a callback. I had broken down the extractor and was spraying it with gun scrubber, when it squirted full force back in my right eye. I think that a red hot poker would have hurt less the instant this stuff hit me. Thank god that our shop has a eyewash station at the door. After a solid 5 minutes of flushing, I could still barely open my eye. After 15, it was ok, but I have a little chemical burn on my tearduct. Certainly not life ending injuries or debilitating but just the same... take a minute and think twice before you clean your guns with any solvents without eye protection on .... I will next time for sure!
