WAT DO U MEAN BY EYE BALL?

The globe-shaped portion of the eye surrounded by the socket and covered externally by the eyelids.The human eye is roughly spherical in shape. It is bounded by three distinct layers of tissue. The outer layer, the sclerotic coat, is extremely tough. It is white in color (the ?white" of the eye) except in the front. Here it forms the transparent cornea, which admits light into the interior of the eye and bends the light rays so that they can be brought to a focus. The surface of the cornea is kept moist and dust-free by the secretion from the tear glands..
