Upside down goggles can be used to demonstrate human adaptation to inverted vision, and as a method of preventing motion sickness. [2] Hubert Dolezal recommended using upside down goggles for "nausea adaptation" for space travel. [3] They can also be used to train spatial abilities and possibly cognitive functions.

Prism adaptation can be used to rehabilitate the visuo-spatial deficits of neurological disorders such as unilateral neglect.It has become clear that with respect to being used as a long-term rehabilitative tool, prism adaptation is only effective when it is repeated over many sessions and with sufficiently strong prism goggles (Newport and Schenk, 2012).
Prism lenses (here unusually thick) are used for pre-operative prism adaptation. Eye care professionals use prism correction as a component of some eyeglass prescriptions.A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions.
The AN/PVS-7 is a single tube biocular night vision device. Third-generation image intensifiers are able to be installed and are standard for military night vision. Most newer PVS-7 intensifier tubes are auto-gated to prevent image intensifier damage if exposed to intense light. The goggles have a built-in infrared Illuminator for low-light ...
Visual adaptation is the temporary change in sensitivity or perception when exposed to a new or intense stimulus, and the lingering afterimage that may result when the stimulus is removed.
George Malcolm Stratton (September 26, 1865 – October 8, 1957) was an American psychologist who pioneered the study of perception in vision by wearing special glasses which inverted images up and down and left and right.
Basically, pseudoscopic vision is three-dimensional vision in reverse. For example, in aerial photography, swimming pools appear to look like buildings and buildings appear to look like swimming pools. In red and green plotters like the Kelsh and Multiplex this is achieved by reversing the lenses on the 3D glasses. The images will be reverse order.
The patient wears goggles containing a camera that tracks the pupils using infrared imaging; the video eye-tracking system records and sends pupil movement tracings to a computer typically with VNG analysis software. [1] [2] [3] The goggles may also have a cover in order to deny vision for some tests while still recording eye movement. There ...
