Dark adaptor goggles are goggles made with red-tinted plastic lenses. Dark adaptor goggles were invented by Wilhelm Trendelenburg in 1916. [1] The concept is based on the work by Antoine Béclère on dark adaptation of the eye, where it is noted that fluoroscopy relies on the use of the retinal rods of the eye.
His device used short-focus lenses. Stratton used a one-tube, 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]
