Binocular rivalry is a phenomenon of visual perception in which perception alternates between different images presented to each eye. When one image is presented to one eye and a very different image is presented to the other, instead of the two images being seen superimposed, one image is seen for a few moments, then the other, then the first, and so on, randomly for as long as one cares to look. For example if a set of vertical lines is presented to one eye, and a set of horizontal lines to the same region of the retina of the other ... Including:

An optical illusion is a type of illusion characterized by visually perceived images that are deceptive or misleading [1]. Information gathered by the eye is interpreted by the brain to give the perception that something is present when it is not. There are physiological illusions, that occur naturally, and cognitive illusions, that can be demonstrated by specific visual tricks that show particular assumptions in the human perceptual system [2]. Optical illusion - Physiological illusions. Physiological i ... Including:

Anaglyph images are produced using color filters or computer image processing techniques to combine images from two slightly different viewpoints into a single image. These images may then be viewed with "anaglyph glasses", which use color filters to moderate the light reaching each eye to create the illusion of a three dimensional image. This is an example of stereoscopy. Anaglyph images have seen a recent resurgence due to the presentation of images on the internet, coupled with the availability of low cost paper frames that hold ac ... Including:

In 1838, Charles Wheatstone, a British inventor, discovered stereo vision (binocular vision) which led him to construct a stereoscope based on a combination of prisms and mirrors to allow a person to see 3D images from two 2D pictures (stereograms). Around 1849-1850, David Brewster, a Scottish scientist, improved the Wheatstone stereoscope by using lenses instead of mirrors, thus reducing the size of the contraption. Brewster also noticed that staring at repeated patterns in wallpapers could trick the brain into matching pairs of them and thus causing the brain to perceive a virtual plane behind the walls. This is the ba ...
