Eyestrain brought on by too many hours of looking at low-res, poorly tuned, or glare-ridden monitors, esp. graphics monitors.
I'm getting mad raster burn by looking at this screen
A slang term used by hackers to describe Computer Vision Syndrome (CVS).
Irritation of the eyes that occurs after hours of staring into a LCD or CRT computer monitor, where the millions of phosphor dots start to "burn" your eyes. This happens especially after looking at plain text for hours, such as when writing code.
Using the green-over-black color scheme while coding reduces raster-burn, as does wearing lightly tinted sunglasses, especially if they are polarized.
"The mirrored sunglasses the teenager worn were round and black, John Lennon numbers. Worn to prevent "raster burn" from the phosphor dot symbols displayed on his screen." -Hackers, David Bischoff
