Although Magic Eye puzzles were all the rage some 25 years ago, the idea for these bizarre pictures has been around for decades to study depth perception. Hidden in this picture is a scorpion. This idea dates back to the s, where it was first described by the English inventor Charles Wheatstone. He created a device that could display a slightly different image to each eye, in order to understand how our eyes take in images of 3D objects.
You should 'diverge' your eyes to see the puppy in this picture. To create a Magic Eye image, programmers first start with the hidden image as a grayscale, smooth gradient depth map where dark points that should be furthest away are darker and closer points are in lighter shades, reports Mental Floss. Then, the 2D pattern is placed over the hidden images as a camouflage. The computer uses a Magic Eye algorithm that takes the image model and the pattern and arranges the repeating patterns to the necessary depth of the hidden image.
When someone looks at a Magic Eye, the repeating pattern feeds the brain the depth information encoded into it, and the brain perceives the hidden picture. Using flat images, this was the first time scientists were able to trick the brain into perceiving depth - creating in the first stereoscope. The next big breakthrough happened in , when Dr.
Bela Julesz was able to eliminate the depth cues of a photo, reports the Magic Eye website. Julesz also discovered the first random dot stereogram while experimenting with stereopsis when he created one uniformed image that consisted of randomly distributed dots. In the image, Julesz selected a circular area of dots within the image and slightly shifted the area in a second image, reports Mental Floss.
The random dots contained a hidden shape that could only be seen when you arranged your eyes at a certain point.
Anyone staring at the two images would see a floating circle, even though the random dots had no depth cues. These findings supported Julesz's hypothesis that depth perception occurred in the brain and not in the eyes.
To create a Magic Eye, programmers first start with the hidden image as a grayscale, smooth gradient depth map where dark points that should be furthest away are darker and closer points are in lighter shades. Pictured is a kite. Then, the 2D pattern is placed over the hidden image, which is a duck in this picture, as a camouflage. When you let your eyes diverge, instead of looking directly, for example, an icon, each eye is seeing its own icon.
Because your brain is trained to transform two similar pictures into one, it automatically assumes you are seeing one icon that is further back and larger — not two that are closer. This happens across the entire image and every icon is being interpreted as one.

After that , lo and behold, just in time for us '90s kids to freak out over them, engineer Tom Baccei, 3D artist Cheri Smith, and programmer Bob Salitsky created Magic Eye in , building on the research that came before them.
Our eyes have the ability to understand something 2D as being 3D due to the depth in the image — which, in the case of Magic Eye, is provided by the two different images overlayed on each other that make up the whole. When we see a "3D" image, it isn't actually jumping out in front of us; however, our eyes "understand" that it is leaping out of the dimension because the two images laid on top of each other allow our eyes to find the difference in depth between them.
It's worth noting that our eyes technically see things from different angles ; as such, they're used to making up the difference between those angles based on our depth perception. This is why people who have an astigmatism or worse vision in one eye than the other may struggle to see the image in Magic Eye pictures — their eyes have a harder time making up the difference between the angles.
A lot of people can pick up on these images pretty quickly, but for me, it's a real struggle. Luckily, the team over at MagicEye. It should be blurry.
