According to Wikipedia, Magic Eye is a series of books published by N.E. Thing Enterprises (renamed in 1996 to Magic Eye Inc.). The books feature autostereograms (precisely, random dot autostereogram), which allow people to see 3D images by focusing on 2D patterns. The viewer must diverge his or her eyes in order to see a hidden three-dimensional image within the pattern.
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.
Magic Eye stereograms have been used by orthoptists and vision therapists in the treatment of some binocular vision and accommodative disorders.
Personally, I have always loved the Magic Eye series. For some reason, my eyes almost automatically focus on seeing the images. I know other people who can’t see them for the life of them.
What about you? Do you see them? Or find them fascinating? Or is it just me?
