Work with Light
- Wrote that every point on a body in the field of vision emits a ray of light in all directions
- The only ray that can enter the eye are those that impact the pupil, which functions as a diaphragm
- Reversed the traditional visual cone
- All the rays are then refracted within the normal eye to meet again at a single point on the retina.
