I've been a software developer for years, and even prior, as a kid spent many many man-hours in front of a monitor.
I'm wondering from the HN crowd if others experience this self-dubbed "pixel vision", where when you look at a distance or don't focus your eyes on anything particular it seems like there are still RGB pixels twinkling at you. It's hard to describe sometimes because it's not an in-your-face, immediately-obvious-all-the-time thing. It's like a "soft filter" put over the world.
