Stratton, 1896

LITThe eye's lens projects an inverted image onto the retina; the brain never "sees" the retinal image as a picture, so nothing needs flipping back. George M. Stratton wore lenses that inverted his visual field: first for a few days (1896), then about eight days in 1897 (durations cited from memory, unverified in detail). He reported that, over days, acting in the inverted world became easier and at times felt normal. Later replications (e.g., Kohler’s Innsbruck goggle studies) found similar adaptation.

MODELA toy adaptation curve: reaching for targets in an inverted view, error falls exponentially with "days" (time constant my choice). Tap the targets.
