Using a camera seems to exacerbate a lot of eye problems. Though the D70 viewfinder is not particularly good, I have found that my eyes have just as hard a problem with excellent viewfinders. I have an astigmatism; and, even 20 years before I had to wear glasses for sight correction, using a camera (even with great viewfinders) would cause the double vision to increase. Like others here, I now have no line bifocals; but, I hate wearing them when I use the camera. I find it difficult to consistently line up the same section of the glasses with the viewfinder. So, I find that, yes, using the camera does cause my eye strain; but, that the D70's "poor" viewfinder seems to have nothing to do with it.
