Dysmetropsia in one eye, a case of aniseikonia, can present with symptoms such as headaches, asthenopia, reading difficulties, depth perception problems, or double vision. [3] The visual distortion can cause uncorrelated images to stimulate corresponding retinal regions simultaneously impairing fusion of the images.
Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception. It is a major factor in perceiving the world in three dimensions . Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known ...
Even with good visibility, misleading visual inputs such as sloping cloud decks, unfamiliar runway grades, or false horizons can also form optical illusions, resulting in the pilot misjudging the vertical orientation, aircraft speed or altitude, and/or distance and depth perception; these could even combine with nonvisual illusions from the ...
Visuospatial skills are needed for movement, depth and distance perception, and spatial navigation. [1] Impaired visuospatial skills can result in, for example, poor driving ability because distances are not judged correctly or difficulty navigating in space such as bumping into things. [1]
Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes. Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not exist.
The perception of depth in such cases is also referred to as "stereoscopic depth". [1] The perception of depth and three-dimensional structure is, however, possible with information visible from one eye alone, such as differences in object size and motion parallax (differences in the image of an object over time with observer movement), [2 ...

The vergence-accommodation conflict can have permanent effects on eyesight. Children under the age of six are recommended to avoid 3D displays that cause VAC. [12] Meta Half Dome prototypes addressed the problem with variable focus lenses that matched focal depth to vergence stereoscopic depth. [15]
