The sclera is the white part of the eye that encircles the cornea. In fact, the sclera makes more than 80percent of the surface area of the eyeball, reaching from the cornea all the way to the optic nerve, which exits the back of the eye. Only a small portion of the anterior sclera is visible.

The cornea is the clear front part of the eye that includes the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea estimating for approximately two-thirds of the eye's total optical power.

The optic nerve attaches the eye to the brain. The optic nerve transmits the impulses formed by the retina, the nerve layer that lines the back of the eye and senses light and generates impulses. These impulses are transmitted through the optic nerve to the brain, which interprets them as pictures.

There are a number of eye fatigue tips., but utmost is to take rests when you can and blink often.
