Autostereoscopy is any method of displaying stereoscopic images (adding binocular perception of 3D depth) without the use of special headgear, glasses, something that affects vision, or anything for eyes on the part of the viewer. Because headgear is not required, it is also called "glasses-free 3D" or "glassesless 3D".
An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two. The 3D scene in an autostereogram is often unrecognizable until it is viewed properly, unlike typical stereograms.

A variation on the anaglyph technique from the early 2000s is called "Anachrome method". This approach is an attempt to provide images that look nearly normal, without glasses, for small images, either 2D or 3D, with most of the negative qualities being masked innately by the small display.
The images presented to each eye are slightly different, and are constructed such that the brain can combine them to create the illusion of depth via stereopsis. This allows viewing of 3D images without the need for specialized glasses, making it a practical and convenient solution for a wide range of applications.
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
Back in 2007, scientists at MIT developed an optical illusion to determine if you need corrective lenses. It does the same thing as the trusty big 'E' -- but way more fun. It does the same thing ...
Lenticular arrays have also been used for 3D autostereoscopic television, which produces the illusion of 3D vision without the use of special glasses. At least as early as 1954 patents for lenticular television were filed, [62] but it lasted until 2010 before a range of 3D televisions became available. Some of these systems used cylindrical ...
