Yep, had a friend recently collapse his LH eyeball.That sucks but luckily it's not worse. One thing that could've happen is you unknowingly rubbed your eye thus introducing a foreign object where it doesn't belong or just scratching yourself. Happened to me with a tiny shard of glass off the cracked back of an iPhone. The lady assistant from the eye dr said "you'd never rub your eye if you saw what I see on a daily basis."
Was at work cleaning a bench and something flipped up and smacked him in the lens. A day later they’re rushing him into surgery to rebuild the lens and stop the eyeball from further “leakage”. He never felt a thing other than something like dust in his eye. He has less than a 50% chance of regaining sight in that eye now.
So yup, coukd have been worse and I’m grateful it wasn’t.
still sucks though…
