I bought a new ViewSonic VT3200LED TV, and it seems to hurt my eyes. I sit about 10 Feet away. Do I need to return it? If so, I am looking at the Sony 22" LCD HDTV (KDL22BX320). Is that a good one?

This really isn't a vision question. <Moved to Electronics>

Turn the brightness down on it. There should be a backlight adjustment... that will be the one you will want to adjust first. Also make sure that when you set it up that you choose home mode and not store mode. Most TVs will be very bright by default.
