The top and bottom images produce a dent or projection depending on whether viewed with cross- () or wall- () eyed vergence. 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.
Creative visualization is the cognitive process of purposefully generating visual mental imagery, with eyes open or closed, [1] [2] simulating or recreating visual perception, [3] [4] in order to maintain, inspect, and transform those images, [5] consequently modifying their associated emotions or feelings, [6] [7] [8] with intent to experience a subsequent beneficial physiological ...
Optical illusion is also used in film by the technique of forced perspective . Op art is a style of art that uses optical illusions to create an impression of movement, or hidden images and patterns. Trompe-l'œil uses realistic imagery to create the optical illusion that depicted objects exist in three dimensions.
The health effects of 3D are the aspects in which the human body is altered after the exposure of three-dimensional (3D) graphics. These health effects typically only occur when viewing stereoscopic, autostereoscopic, and multiscopic displays. Newer types of 3D displays like light field or holographic displays do not cause the same health ...

Enter: cognitive shuffling, a method that's going viral as a "hack" for dozing off quicker. It's perfect for when you have a million racing thoughts—like how you're going to get the kids to ...
Aphantasia. A representation of how people with differing visualization abilities might picture an apple in their mind. The first image is bright and photographic, levels 2 through 4 show increasingly simpler and more faded images, and the last—representing complete aphantasia—shows no image at all. Aphantasia ( / ˌeɪfænˈteɪʒə / AY ...
Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality. Because entoptic images are caused by phenomena within the observer's own eye, they share one ...
