Hi,
I assume you saw at least one ophthalmologist. Obviously all we can do is say we hope you are better and suggest things to check out. I have extremely dry eyes (that water because they are trying to help the dryness) and sometimes get scales on them, etc. My vision is worse in the mornings, kind of feel like I am in the tunnel sometimes. Light hurts them and I have trouble seeing at night. I have Fuchs dystrophy which is a type of cornea dystrophy. Having said all of that, when they get itchy and even painful, my ophthalmologist orders specific antibiotic drops for eyes. Don't rule out an infection.

The other suggestions about plenty of water, good moisturing eye drops if the ophthalmologist says okay, etc. can help if you don't have an infection.
