In 1851 the German physicist and physiologist Herman von Helmholtz revolutionalized the field of ophthalmology with his version of the ophthalmoscope. (Unbeknownst to Helmholzt, Charles Babbage invented the first ophthalmoscope 4 years earlier and gave it to a physician for testing, but it was soon misplaced and forgotten. Modern ophthalmoscopes are used during every eye examination by optometrists and ophthalmologists and are used to examine the retina and structures at the back of the eye.) But Helmholtz's endeavors were increasingly focused (pun intended) on the physiology of the senses and culminated in theories on color vision, depth perception and motion perception.
