I've been a software developer for years, and even prior, as a kid spent many many man-hours in front of a monitor.<p>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.
I've experienced the same thing, especially after many hours staring into a monitor. My guess it may be a neurological thing of the eyes/brain adjusting to the ever changing pixel flickering through out the day, similar to after-images and retinal fatigue.
