Having had this on my right eye a few months ago, I can confirm, the pain is excruciating, and my body was in panic mode. I rushed to the ophtalmologist, who confirmed I had a large abrasion. She says some people sleep with their eyes half open, and because you don't blink while sleeping, that exposed part of your eye completely dries out, and when you blink in the morning, you can rip away a chunk of the cornea.

After that, I've been doing Systane ointment or gel, right before going to bed, and eye drops in the morning, as soon as I wake up. Every single day. The doctor said it doesn't happen overnight, it's usually a drying out over multiple days, but I'm not taking any chances.

Do yourself a favor and have a doctor check it out.
