I have contacts that correct my vision to just about 20/20. Maybe I just have higher than average DPI screens, but most sites (hn included especially) are simply too small for me to sit at a comfortable distance and read comfortably. I don't know where the rest of you eagles come from.

Agreed. Eyesight doesn't get better as you get older, it only gets worse. Why strain your eyes trying not to "look old"? Your eyes should be relaxed when you read.
