It could be there is more going on indeed. “Just” dry eyes (which is horrible on its own) is easy to diagnose for an eye specialist. Dry cornea is easy to see. You might want to be checked for Thygeson. (I was diagnosed with Thygeson recently (besides other issues) and I had burning eyes too. Thygeson is rare and difficult to diagnose. The eyes are not red and the dots can be so small that they are hard to detect. Now on steroids which seems to help somewhat).
