Optical Illusions

Move your head back and forth while staring at the center black dot,
you will notice the outside rings moving, but are they?

        

       Optical illusions have always caught my curiosity. The way they capture you in an out of mind experience is quite interesting. Optical illusions are visually perceived images that differ from objective reality. In other words, the image may question what you may or may not be seeing.

       The three types pf illusions are literal, psychological, and cognitive. These all affect the eyes, brain, and conscious. These illusions all can be delt with things such as movement, color, tilt, position, brightness, and many other factors. As the one showed below if you stare closely at the yellow dot, you will see the outer blue dots start to disappear and come back at different intervals. This is just one example of how a picture can altar what you think your seeing but actually the blue dots remain always, as the picture above does also.
