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.

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.
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).
Moreover, studies have found that stimuli can rival each other, which explains why higher numbers of simultaneous stimuli lead to lower stimulus adaptation. Studies have also found that visual adaptation can have a reversing effect; if the stimulus is absent long enough, the aftereffects of visual adaptation will subside.
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 ...
Night vision is of lower quality than day vision because it is limited in resolution and colors cannot be discerned; only shades of gray are seen. [1] In order for humans to transition from day to night vision they must undergo a dark adaptation period of up to two hours [ 2 ] in which each eye adjusts from a high to a low luminescence "setting ...
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.
In vision therapy of amblyopia and of intermittent central suppression, liquid crystal devices have been used for purposes of enhanced occlusion therapy. In this scenario, the amblyopic patient wears electronically programmable liquid crystal glasses or goggles continuously for several hours during regular everyday activities.
