The refraction of light. Concept introduction: The sense of vision within the eyes uses photoreceptors to detect light, color, and movement to observe the visual images of the environment. The physiology of vision is expressed as the light enters into the eye and is transformed into electrical signals. Then, the electrical signals are transmitted to the brain for interpretation and integration. The physiology of vision primarily starts with the refraction of light. Then, this process continues with focusing of light on the retina, phototransduction, and the relaying of sensory input along visual pathways.
