TV and Computer

To me, I think I've made my DR worse by watching too much TV and being on the computer too much. It seems like everything should be almost 2D since that's the way it is on TV and the computer. It makes me feel sort of funny while being outside because of how "interactive" everything is. Can anyone else relate to this? I think I might try going without either, or at least use them a minimal amount, for a week or so. Maybe that way I can feel more real.
