Thanks for all the suggestions guys. I actually did make a appointment with my regular MD before I go to the eye specialist. My regular eye doctor can't find anything wrong with my eyes so I thought I might try my regular MD just to rule some things out.
Just to answer a few of your questions.
We haven't changed anything in the room. Same lighting we've always had. I bought a plamsa set mainly because I wanted to avoid some of the LCD drawbacks (motion blur and brightness) and liked the overall look of them better.
I thought about the distance I am from the set and FOV. I really wanted a 58" set when I bought last April but they were not out yet and I had a CC return credit from a broken TV I had to use by a certain date so I thought I could live with a 50" set.
Just a side note I bought the Plamsa set in April and didn't really start having these symptons till the first part of July. It would almost seem if the TV was causing issues I would have seen them sooner.
I know (or think I do) something else is causing the actual problem but I wondered if the actual type of TV was making the issue worse.
I do wear corrective lenses. Just got new ones because my prescription had changed but it didn't make any difference with the problem I'm having. I wear progressive bifocals for near and far correction and I have a real bad astigmatism and I have prism added to correct my eyes wanting to see double images. Doc says I have a pretty healthy prescription going on
I think they are just going to give me coke bottles next time I go in
I'll keep searching and if I have to try a different TV it would be worth it to me. I might try watching some racing on the Toshiba 40" LCD this weekend from different distances and see how it feels. I tried moving a little closer to the Panasonic plasma the other day but it still seemed way too bright to my eyes and this is with the settings turned way down. Very frustrating
Anyway thanks again for the responses. I really do appreciate the input.
Any other questions or suggestions please keep them coming.
