I once told a tale about how safety glasses saved my eye sight. I have always been and will always be a safety glasses extremist. No one works in my labs without safety glasses.
Even when I am at home, I use safety glasses when I'm doing things like using power tools (saws, trimmers, drills etc..) or mixing a really strong drink (OK, maybe not that one, but you get the point).
I am slowly (sloooooooowly) building a bar in my basement. Tonight, I finally found some time to make some progress. I went to my shed to cut some lumber to the requisite size. I was wearing safety glasses as usual. During the course of events, I measured and marked a piece of plywood without glasses on as tape measures and pencils are not commonly known to cause eye injuries.
I didn't put the safety glasses back on.
As I started to saw through the wood, I hit a knot and a small chunk of celluose, hemicellulose and lignin (i.e. wood) flew through the air and nailed me in the eye. It specifically hit my sclera (the white of my eye). It didn't hurt much, but I knew something had happened.
I had my photographer-wife take a picture so I could put it on my blog and gross some of you out:
From my perspective, it looks a lot worse. At this point, I'm not going to seek medical attention since 'tis mearly a flesh wound.
The bottom line: WEAR YOUR FREAKIN' SAFETY GLASSES, DUMBASS!!!!!!!!!!
I am the dumbass for not wearing them like I preach.
Wear your safety glasses, people.
