Some people who have dry eye, don’t have thyroid eye disease. I have dry eye, but not thyroid eye disease. Getting a diagnosis is helpful. Were you diagnosed with thyroid eye disease? How long since your last exam? Whenever someone get sudden vision issue, I suggest they test their blood sugar. That was one sign I had type 1 diabetes. It left once I got my sugar level down

Chronic dry eye often requires multiple treatment measures. There are probably some threads about it here. Many of us do daily warm compresses, eye gel drops, moisturizing drops, nighttime ointment, etc. Some use prescription medications. I’ve tried 2 that didn’t help. Planning to try another one.

I hope you can figure out what’s going in and fix it,
