I always have glasses on in the shop. Have to mainly cause I have 40 something eyes. A month ago, my brother-in-law was camping. Used an ax to chop some stakes. A little piece flew off and hit him in an eye. He said it hurt, but went to sleep anyways. Next morning, woke up and could not see out of that eye. When we got there to rescue him to hospital, it looked like someone had punched him hard in the eye. Blood red, black and blue. All from a small wood chip, blunt trauma to the surface of the eye. He used to be 20:15. Hunter. I called him eagle eyes. The damage is permanent. He is effectively blind on one eye.
If you dont wear shop glasses, start wearing them. The other lesson is if u get an eye injury, go to doc immediately. His doc told him that it was the long time between injury and treatment that ended his vision.
