Frederick Brock made many contributions to vision therapy, and his work focussed mainly on the application of vision training to the diagnosis and therapy of binocular dysfunction. [1] Brock trained his patients with rich stereo images which closely resembled the natural environment, and favored these over the use of (simplified) stereographs. [2]
The cheiroscope is used for diagnostic purposes to test binocular vision, to assess certain conditions of strabism in particular related to binocular stability and alignment, [2] cyclotropia, [3] and the presence and extent of suppression. [2] It can also be used in vision therapy to train amblyopic subjects in desuppression and eye–hand ...
Note also: Without optic nerves, the disembodied eyes in the figure would not perceive an image 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.
The card image is magnified, offering a wider field of view and the ability to examine the detail of the photograph. The viewer provides a partition between the images, avoiding a potential distraction to the user. A stereo transparency viewer is a type of stereoscope that offers similar advantages, e.g. the View-Master.
The Van Hare Effect is a 3D stereoscopic viewing technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision using psychophysical percepts. The Van Hare Effect creates the illusion of dimensionality, rather than actual dimensionality in the subject being viewed.
Individuals with disordered binocular vision and who cannot perceive depth may require a wiggle stereogram to achieve a similar effect. The simplest type of autostereogram consists of a horizontally repeating pattern, with small changes throughout, that looks like wallpaper.
In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and shares no field of view between them, like in some ...
In contrast to an eye patch that occludes the whole visual field of one eye, binocular occlusion allows some degree of binocular vision; more particularly, it emphasizes the role of binocular functioning in peripheral vision: objects that are located to the right can only be fixated by the right eye, and those located to the left only by the ...
