The Human Eye Model is enlarged by three to five times that of the size of the human eye. This allows patients, doctors, and future optometrists an opportunity to examine one of the smallest organs of the human anatomy in clear detail. The human eye is a sense organ that reacts to light and allows vision. Rod and cone cells in the retina are photoreceptive cells which are able to detect visible light and convey this information to brain. Human Eye Model helps people study it.
