Hello,
I have also had issues with dry eyes in the last 6-8 months. I've had RSD for 4 years now.
I was told that I could not wear contacts anymore and probably can't ever again. I bought a humidifier that I keep at my desk while I'm at work. That has helped a lot with the dry eyes. The drops do help, but I've found that it only helps for a few minutes. There are also gel drops that you can put in your eyes at night that is a little thicker and lasts longer. You can get them over the counter too...
I have an appt this week to see if I can wear contacts - even for a few days a week... We'll see.
