Thanks for the replies!! Jessica, I also had a lot of problems with dry eyes while wearing contacts. I tried wearing glasses but still had problems. I think this definutely relates to POTS. Thanks guys. I feel better knowing that I am not alone in this. I also have bloodshot eyes. The thing that scared me the most happened a couple of weeks ago. I was out at a restaurant with my boyfriend, and out of no where, I saw a patch of wavy lines. It my vision darkened over the course of about ten minutes to the point where I could barely see. I was getting all kinds of halos off of everything around me. Anyways, it went away in about twenty minutes. I was scared to death!! I then woke up later that night with the worst headache of my life. I called my cardiologist and he said it sounded like migraines. A couple of days later, I had the same vision problem, but it only lasted for about five minutes. This time, there was no headache. This is a new thing for me and very scary- does anyone have any experience with this? Sorry if my writing is kind of choppy. I just got back from an eight hour day of work, and as you all know, that is no easy feat. Well, if anyone has any info for me, please let me know. Take care all -Stacey
