I don't have glasses too and I don't have any problems with any of monitors (CTR Or LCDs). Few months back I went to an eye specialist for complete checkup and after test I got the Report "NO Problem with your eyes" Lol
I have the same problem except my right eye is the blurry one. Doctors told me i have an astigmatism so you should get it checked out.
I have a computer since 1981 and it's only recently that I begin to have some light problem...Beginning of the end I guess....
