not nearly as bad as that - but when i used to have the lenses that you clean and reuse - (I used to sterilize the lenses with some germ destroying stuff overnight - but with a little tablet that would slowly neutralize the the liquid so it was safe to use the lenses the next day) - i once (drunk i expect) didn’t put the neutralizing tablet into the cleaning box, popped a lens in the next day and FUCKING HELL - proper proper awful burning sensation - really nasty!
i’m amazed i didn’t completely fuck my eyes over actually given the amount of times i’d come home when i was about 17 or so, steaming drunk and having to struggle with the cleaning routine - christ knows how i managed it effectively all but one time.
