Magic Eye is a series of books published by N.E. Thing Enterprises (Renamed in 1996 to Magic Eye Inc.). The books feature autostereograms, which allow people to see 3D images by focusing on 2D patterns. The viewer must diverge his eyes in order to see a hidden 3-dimensional image within the pattern.

It was soon followed by sequels which were also extremely popular, and the three books spent a total of 34 weeks on the New York Times Bestseller List. Several other books and videos have been released since then, and Magic Eye stereograms have been featured on postcards, mousepads, lunch boxes, and even neckties. Magic Eye stereograms are also featured in a comic syndicated by Universal Press Syndicate which appears weekly in many newspapers around the world and features a stereogram with a hidden image for readers to discover. In 1979, Dr. Christopher Tyler, a student of Bela Julesz and a visual psychophysicist, combined the theories behind single-image wallpaper stereograms and random-dot stereograms to create the first random-dot autostereogram (also known as single-image random-dot stereogram) which allowed the brain to see 3D shapes from...

The Magic Eye images have a horizontally repeating pattern which differs slightly with each repetition, therefore giving the illusion of depth when each eye focuses on a different part of the pattern. The stereograms were created using a patented process that allows colorful patterns to be used in creating the final images. An illusion is a distortion of a sensory perception. ...


Magic Eye images have also been used by children and adults for science and other purposes. Magic Eye stereograms are frequently used by orthoptists and vision therapists in the treatment of many binocular vision and accommodative disorders [1]. Orthoptics (from the Greek words ortho meaning straight, and optikas meaning vision [1]) is the discipline dealing with the diagnosis and treatment of defective eye coordination, binocular vision, and functional amblyopia by non-medical and non-surgical methods, e. ...
