Dude - it was due to one moment of carelessness. A broken tree branch was suspended above my ex-wife’s walkway. I saw it and told her I’d get it down. She told me to do it later, but I insisted - saying, “you know how I hate chores - take advantage of my motivation”. I yanked it and something (seed pod, acorn, piece of branch) hit me square in the eye. Annoyed me at first (like pinkeye) and then just got worse. Tried things like contacts for weeks/months to help cornea heal, but it just kept retearing - like a scab. Often it would retear at night, early morning because that’s when your eyes are very dry - eyelid would just rub up against cornea. Wearing safety glasses (like a dork) and I save myself 18 months of sporadic agony. If this happened more than about 40 years ago, I might have been incapacitated forever. I finally bit the bullet and got a procedure done (superficial keratectomy) - 5-10 minutes and it was magic. Had to have a contact in for about a month to shield cornea from eyelid while it healed, but it’s back to normal though some days I might need to use eye drops for minor irritation.
Anyway, sounds like those guys stared a bit too long at the laser light and learned a short-term but valuable lesson.
