I've always used wrap around safety glasses when running the cutoff wheel. Tonight while trimming the longerons, I found that glasses aren't adequate eye protection for the task. Evidently the glasses had slid down my nose slightly and either a piece of abrasive or aluminum dust found its way into my left eye. I was hoping the massive amount of tearing would flush out what ever it was and relieve the irritation, but it was not to be.
Another half hour of flushing with saline and direct spray in the shower with no improvement convinced me it was time to head for what passes for an emergency room here. Two hours later I was diagnosed with a corneal abrasion. The good news is that the doctor saw no remaining foreign objects in my eye, and it should heal in a day or so.
The anesthetic only lasted an hour, and the doctor warned me not to use it more often than I absolutely have to, so I currently am not a happy camper...
Bottom line: FROM NOW ON I WILL ALWAYS WEAR A FACE SHIELD WHEN RUNNING A CUTOFF OR ABRASIVE WHEEL!!
