How Do Our Eyes Help Us?

Every human has two eyes. Each eyeball rests in a skull socket, or aperture. The back and sides of the eye are shielded by the skull bone. The front of the eye is shielded by the eyelid. Eyelids move tears around the eye via blinking. Eyes are kept moist by tears. Dust and other debris that can enter the eye are caught by the eyelashes. The eyeball is held in position and moved up, down, and laterally by six muscles.

The Parts of the Eye

How interesting it is to think about this unique organ of our body.There are numerous questions which come to mind like what makes us see? How does it function? And many more, so let's have a quick look at the various parts of “The Eye”.


Eye being the sensitive organ needs its protection for its healthy functioning so it is protected naturally as a transparent fluid is present inside the eyeball. This jelly is surrounded by three coats or layers. The cornea and sclera, or the white component of the eye, make up the outer coat. The cornea serves as the window through which light enters the eye.The front portion of this coat is made up of the iris, or  the colored part of the eye.


The pupil, located in the iris's middle, is where light enters the eye. To admit more or less light through the pupil, the iris opens and closes. The retina is the term for the eye's inside layer. The retina is made up of rods and cones of different cell types. They are photoreceptor cells. Electrical impulses are sent as a result of the cells collecting light. The optic nerve is responsible for carrying these messages to the brain.
