It is probably dry eye. It is common in autoimmune diseases. I was diagnosed with it and had those symptoms you listed. I take systane eye drops for it. An optomologist can test you for it. They will give you a list of drops they recommend. Visine is not recommended.

I was told I have dry eyes and to put warm moist compresses on them. ??

What he said...

Dry eyes is also also caused by AS and it could lead to iritis . Over the counter eye drops twice a day has worked for me.

Yep me too
