Through his dissection of the eye, he discovered its different sections and layers: the "skin" of the eyeball comprising the cornea (the clear part at the front of the eye through which light begins to be focussed into the eye) and sclera (the white of the eye), the iris (the colored part of the eye surrounding the pupil), the retina (containing the cells converting light into neural activity), and the choroid (a layer between the retina and the sclera comprising connective tissue and blood vessels nourishing the retina). .
