I had dry eye when I use to work at a store. I can feel my eyes get scratchy and dry many times just walking through stores. I also had dry eye when the air blew in our other house from ceiling vents. I would wake up with my eyes glued shut and bright red. Now that we have air from the floor vents it doesn’t ever happen.
I use to put a thick drop in my eyes that made it impossible to see once I put them in. So it was the last thing I did at night. They helped a lot.
It may have been seasonally worse too.
