In my case my eyes just kept getting drier and drier, and that eventually caused conjuctivitis (inflammation of the eyelid and the covering of the eye). It was mistaken for an eye infection originally. Conjuctivitis + contacts led to an injury of the epithilium, either caused by the contacts literally bonding to and ripping off the epithilium, or by debris being caught and scratching, unable to be washed away due to lack of moisture. The symptoms were cloudy, blurry vision, itchiness, sensitivity to light, and pain. Cloudy vision and pain are f'in scary.

In my case I ended up with lesions that had to be treated with antibiotics, lubricating gel, and a kind of "bandage" contact lens, since the inflammation of the eyelids can cause further damage of the eye.

Please do be careful with your eyes. Don't sleep in your contacts, use lubricating drops, and if you feel debris or other discomfort, take them out!

I was lucky thanks to antibiotics warding off any potential infection. An infection coupled with an injury can threaten your sight. The prognosis is generally pretty good for minor epithilium and corneal damage, usually. For me, it was mind-alteringly painful, but after healing my vision is pretty much perfect with the glasses I had before. Despite being annoyed by my glasses, I am truly thankful that I can see! It is hard to communicate what 2 weeks in a dark room with the question of blindness stirring in your head can make you face.
