Inverted glasses

Reversible glasses wide field of view (147 ° x 68 °)

Homemade inverted glasses

Invertoscope with right-angled prisms

The reversal glasses used for experiments with the visual perception of humans. When wearing the glasses , the visible image is turned upside down by prisms . The experiments deal with how learning processes in the brain adapt to the reversed image so that the ability to act is restored. Corresponding glasses are also called invertoscopes.

It has been shown that after a certain period of time (approx. Eight days) when the glasses are worn continuously, people get used to it, so that they are fully able to act again. The image is still perceived as “upside down”.
