Brain Stirring Optical Illusions
If you’ve ever felt like you go a little cross-eyed after taking a peek at an optical illusion, then you know they can be a pretty intense phenomenon. What your eyes perceive when looking at one of these images is actually a visual illusion; you see the image as something different than what it is because the different cells and receptors in your eyes distinguish images and colors at dissimilar speeds. The eye can only receive a limited amount of visual stimuli, but as your brain constantly processes the visual information, it gives you the illusion of continuous sight. Whether it’s an optical, physiological or cognitive illusion, the design plays a trick on your eyes (and mind). Check out some of the interesting illusions below—but beware, you may not be able to absorb them all in one sitting.

Kaleidoscopes

Wormhole

Bull’s-Eye
If you stare at the center of the image, it looks as if the outer rings are rotating in alternating directions—an effect meant to mesmerize the viewer. Photo courtesy of Todd A. Carpenter
Starbursts
These bright purple and green star-like shapes appear to be moving, which can be a little nauseating if you stare at it for too long. Photo courtesy of Angie Armstrong
