For thirty years, Magic Eye has fascinated children and adults alike worldwide with its amazing 3D images. The first new book in five years from this New York Times bestselling property! Single image stereogram (SIS). SIS differs from earlier stereograms in its use of a single 2D image instead of a stereo pair and is viewed without a device. Thus, the term is often used as a synonym of autostereogram. When the single 2D image is viewed with proper eye convergence, it causes the brain to fuse different patterns perceived by the two eyes into a virtual 3D image without, hidden within the 2D image, the aid of any optical equipment. SIS images are created using a repeating pattern. [18] [30] Programs for their creation include Mathematica. [31] [32]

Another way is to stare at an object behind the picture in an attempt to establish proper divergence, while keeping part of the eyesight fixed on the picture to convince the brain to focus on the picture. A modified method has the viewer focus on their reflection on a reflective surface of the picture, which the brain perceives as being located twice as far away as the picture itself. This may help persuade the brain to adopt the required divergence while focusing on the nearby picture. [28] Mapped Textured Stereogram (MTS) where a textural image is mapped onto a depth-map rather than mapping a random pattern. It is generally thought that amblyopia is a permanent condition, but NPR reports a case where a patient with amblyopia regains stereo vision ( Susan R. Barry). [24] Julesz, Bela (1960).

For Smith, Magic Eye is still very much alive, even if the initial fervor has died down. She and her small team have turned Magic Eye into a creative agency of sorts, where they make custom work for companies who want advertisements, posters, and products emblazoned with Magic Eye’s distinct brand of visual chaos. They’re currently working on a 25th anniversary edition of a Magic Eye book, and recently made a poster for Steven Spielberg’s Ready Player One. Stork, David G. and Rocca, Chris (1989).
