An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a perception that does not tally with a physical measurement of the stimulus source.
There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, color, size, position, tilt, movement), and cognitive illusions, the result of unconscious inferences.

These optical illusions for kids help them in increasing concentration power and sharpen their focus. Though these optical illusions are for kids, but adults will enjoy them too. As this collection is taken from all those chain mails, I have been getting, I don’t have the actual source of these illusions. But nevertheless, these illusions will blow away your lack of focus.
Pink Dots
If your eyes follow the movement of the rotating pink dot, the dots will remain only one color, pink. However if you stare at the black ” +” in the center, the moving dots turns to green. Now, concentrate on the black ” + ” in the center of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating. It’s amazing how our brain works. There really is no green dot, and the pink ones really don’t disappear. This should be proof enough, we don’t always see what we think we see.
