Optical Illusion….How Many Black Dots Do You See??

Here is an interesting Optical Illusion for you!!  How many black dots do you see??  There are NONE!!

Keep staring at one of the white dots….you will see that it is white and never black…only the ones that you are not directly staring at seem to be “blinking” black or gray.  Cool huh??

It is your Retina playing tricks with you….creating an AFTER-IMAGE.
