1800s Model Eyeball
1800 – 1899:Optical Model of the Eye
“René Descartes suggested in 1637 that to understand the properties of the eye, one should study the eyeball of a recently deceased man or a freshly killed large animal. Beginning in the late 17th century, optical models provided an alternative. The lens of the model projects an inverted and reversed image onto a matted screen on the back. Two lenses can be placed in front of the eye to demonstrate the function of corrective lenses for near- and farsightedness.”
