For a few weeks I have noticed that sometimes my vision in my right eye gets foggy when i blink and it goes away when I blink. I visited the doctor and they could not find anything, but I mentioned I was having sinus/allergy problems so they thought that maybe it was just my allergies acting up. Though just yesterday when my eye got foggy I looked into the mirror and noticed a thin layer of film that moved when I blinked and it made my vision clear again and when i kept blinking it went over my pupil again and made it foggy. When I put in drops I have relief for some time before it comes again. So now that I know what was the cause, what is this called? is this just dry eyes or allergies? thanks!
