Optical illusions are usually two dimensional images that “trick” our eyes into seeing something that isn’t really there. This is because our eyes have evolved to function in the three dimensional world we live in. We are constantly making subconscious judgements of distance and space and shadows and light, in order to understand and navigate our world. An optical illusion image can present some of the same cues in a two dimensional plane, causing the eye and brain to interpret the visual information incorrectly. Take a look at some of the fun optical illusions below and see if your eye can be fooled too!
Cool optical illusions videos
1. Eye Waves
Whoa, totally trippy man!
This optical illusion is called motion aftereffect (MAE). As you watch the video, keep you eye at the center and read the letters as they form a sentence. After a short while you will be instructed to look away. This is when the magic happens! If you look at words on your screen, for example, they will seem to move in waves. Look around the room and you’ll see the same visual distortion. The effect lasts for only a few seconds but it is truly a unique experience. Motion aftereffect occurs when neurons adapt to constant movement and have to slowly adjust when the movement stops.
2. Rotating Snakes
The snakes start to move as you look at the image.
This optical illusion works best if you keep your eyes moving around the visual of the circle patterns. As you look about the image, the discs—or snakes—appear to rotate and move. The illusion works because of microscopic eye movement called “saccades.” Interestlngly, when color is removed from the visual, less movement—and sometimes no movement—is detected. This indicates that color patterns and contrast has a lot to do in creating this illusion.
3. Catch the Snakes, Kitty!
Watch this cat fall for the illusion.
For cat lovers we present this cute feline staring at the same rotating snake illusion. She takes a good long look and starts to see the “snakes” start to move. Like any good hunter, it’s game on. Time to attack. But the snakes keep moving, and changing places. Hilarious!

Did you know?
Speaking of mesmerized cats… The word mesmerized is derived from the name of German physician Franz Mesmer, who discovered what he called “animal magnetism”—the natural transference of energy between animated and inanimate objects. The phenomenon was known as mesmerism in the late 1700s. The term hypnosis is more commonly used today, but has the same meaning.

A great idea for halloween or a zombie party.

By painting a hole with the correct perspective, your hand will look like there is a hole right in the middle of it!
6. Face Morph
Watch as celebrities become ugly!
This is a really bizarre optical illusion! It’s called the flashed face distortion effect. Just watch the video and fix your eyes on the cross in the middle of the screen. You’ll see a series of famous celebrities appear to the left and right of the screen. Try not to look away from the cross, but use your peripheral vision to see the faces. Since the faces are familiar, you should recognize most of them. As the video progresses you should see the faces begin to distort and features exaggerate. Go ahead and watch the video without looking at the cross to prove to yourself that the distortions are just an illusion!
