Fading Dot
If you stare at this dot, for few moments it disappears. 
To do and notice
- Step back a few feet and stare at the dot far awhile without moving your eyes or
your head. The dot will gradually fade into the field of green. Some people find that the
dot fades more rapidly if they stare blankly at the edge of the square. As soon as you
move your head or eyes, notice that the blue reappears.
What's going on?
- Even though your not aware of it, your eye is always making tiny jittery
movements. Each time your eye moves it receives new information and sends it to your
brain. You need this constant new information to see images.
You may have noticed that although the dot fades just about everything else in your field
of vision remains clear. That's because everything else you see has distinct edges.
