Upside down goggles, also known as "invertoscope" by Russian researchers,[1] are an optical instrument that inverts the image received by the retinas upside down. It is used to study human visual perception, particularly psychological process of building a visual image in the brain. Objects viewed through the device appear upside down and mirrored. They are constructed using sets of optical right-angle prisms, Dove prisms, or a mirror plus right-angle prisms with unequal catetus.
Purpose
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 to use upside down goggles for "nausea adaptation" for space travel.[3]
They can also be used to train spatial abilities and possibly cognitive functions.[Patents of devices 1]

Under normal circumstances, an inverted image is formed on the retina of the eye. With the help of upside down goggles, the image on the retina of the observer's eyes is turned back (straightened) and thus the space around the observer looks upside down.[4]
History
George M. Stratton designed first upside down goggles for psychological experiment. His device used short-focus lenses. Stratton used a one-tubus, monocular device because this also reverses left and right and he wished to set up an experiment without distortion of depth perception.[5]
In 1931 Theodor Erismann and Ivo Kohler conducted a series of experiments using mirror-prismatic upside down goggles employing only one mirror.[6]
After experimenting since 1984, in 1991 Hubert Dolezal procured an US patent for comfortable light weight upside down goggles.[Patents of devices 2]
Modern upside down goggles consist of two prisms fixed onto a comfortable ski mask-like base.
