Or an eye lash. I woke up that way one time, went to a specialist that morning. My eye was glued shut with gunk from some allergy, though he couldn't tell me what the irritant was. I know it wasn't fleas because we didn't have them in WY. Glad yours is getting better. I keep saline eye drops handy to help wash out allergic reaction to weeds, etc. this time of year. No medicine, just pure water drops...can't remember the name of them just now.
