Thus, a topographically ordered point-to-point representation of the visual world entered the crystalline humor. We must wait until Kepler and Newton in the 17th and 18th centuries for further fundamental understanding of the nature of light and until at least Helmholtz in the 19th century for further advances in understanding visual optids.
