The most scary thing just happened to me today!!!
It started out like a normal scenario, not uncommon to me. I was rubbing my eyes while wearing contacts coz they felt dry. Suddenly my right eye vision, always the right eye having problem, turned blur. A light poke in the eye confirmed that the contact lens was not there anymore. So I went to the restroom to double check, and experience also told me to check whether the tricky bastard went to the lower lid. It wasn't there either, thus I surmised that it must've fallen out. So dizzy with only one eye having corrected vision, I made it back to hall to take out the left contact lens, checking again to see whether the right one was lodged somewhere as it was rare that a contact lens can fall out without touching my face. Furthermore my right eye felt a slight pokey feeling. No sign of it. Halfway during dinner, I started blinking continuously, and OUT OF NOWHERE MY RIGHT LENS FELL OUT TO JUST OUTSIDE OF MY PUNCTA!

OK, not exactly out of nowhere, it was like the upper left corner of my eye. BUT IT CONFIRMED MY WORST FEAR~ THAT THE LENS CAN GO BEHIND THE EYEBALL... ZOMGGG
