Expert Solution
Step 1
The eyes are visual system organs. They provide animals vision, as well as the capacity to receive and interpret visual information, and they enable numerous photo response tasks that are not dependent on vision. Light is detected by the eyes and converted into electrochemical impulses in neurons. The eye in higher organisms is a complex optical system that collects light from its surroundings, regulates its intensity with a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain via complex neural pathways that connect the eye to the visual cortex via the optic nerve.
