Some times the cross eyed 3d images are too large for my old eyes. I found a way to get around this. I keep stepping up the image INCREMENTALLY with the magnifier in my browser. Now I can look at images I could never look at before. I know I look like a cross eyed fool, but if I do it in small increments, and just keep adjusting, it really works. It beats starting 6 feet back from my monitor and moving forward a few inches at a time.
