Vision

Light is composed of photons that make up electromagnetic waves, which are characterized by wavelength, frequency, and amplitude.

Many structures in the human eye, such as the cornea and fovea, process light so it can be deciphered by rods and cones in the retina.

Light is tranduced in rods and cones; visual information is processed in the retina before entering the brain.

Visual signals are processed in the brain through several different pathways.
