Mechanism of Eye
When light beams from outer objects enter the eye, they first land on the cornea. The cornea makes the beams converge and focuses them on the pupil. The light then travels through the aqueous humor to reach the pupil. Some of the light gets absorbed by the iris, but the rest enters the eyeball. The lens then tries to make a convergent light beam, which focuses on a specific point on the retina depending on the nature of the light beam. After being convergent by the lens, the light beam travels through the vitreous humor and lands on a special region of the retina that can make a clear picture. The picture developed on the retina is reversed from the actual object. The image is then converted to a message and received by the optic nerves, which transfer the messages to the optic lobe of the brain. The brain reads the message and develops the actual image of the object. The eye works similarly to a camera, where the iris functions as the aperture, and the retina works like the film of the camera.
Anatomy and Physiology of Human Eye
The human eye’s anatomy and physiology refer to its design, components, and function. The eye is a vital sense organ and is one of the five major sense organs in the human body, including the ear, nose, tongue, and skin. These organs aid in developing, learning, and adapting to our surroundings to ensure survival. The human eye can be called the living camera that transfers information about our surrounding to the brain so our brain can process this information and allow us to see the surrounding
