Introduction: Eye is the sensory organ that is responsible for vision. It is a spherical structure and is filled with a thick liquid. Sclera, cornea, iris, retina, pupil, and lens are some of the important parts of the eye.

Expert Solution & Answer

Explanation of Solution

The amount of light that enters the eye is controlled by a circular muscle called iris. The iris contracts and relaxes during bright and dim light, respectively. A hole in the iris is the pupil through which the light enters. The light passes through pupil and falls on the lens. The lens refracts the light and focusses on the retina. The retina present at the rear end has two types of photosensitive photoreceptor cells called rods and cones. Since these photoreceptors are present at the rear end of the eye, the light passes through neural cells before reaching the photoreceptors. The path of light through the photoreceptor cells occurs in the following way:

Photoreceptors→bipolar cells→Ganglion cells→Axons (of the optic nerve).
