Dailies or hards? Hards you shouldn't. Dailies I'd trash tomorrow just because. And they're cheap.

Don’t wear contacts but suffer from chronic corneal erosion which is caused by an injury to the eye that doesn’t properly heal and can rip back open if your eyes dry out during sleep. I assure you that you want to take care of your eyes when you are sleeping. Searing pain upon waking is not as cool as it sounds.

Yeah if you dusted off in dailies you should irrigate in the morn and maybe take a few hours off.
