Comment Not how the eye works? (Score 1) 152
I guess it would work ok if the display were constantly changing, but static images on the retina fade pretty quickly. You might not notice it, but your eye is constantly moving (this is called saccadic movement) so that you keep being able to see things. Otherwise, you're not going to be able to see the stuff on these displays, because it will fade from vision like the blood vessels between your retina and your cornea.
