The document summarizes the key parts and functions of the eye and ear as sense organs. It describes the three layers that make up the eyeball - the sclera, choroid, and retina. The retina contains rods and cones which are responsible for vision and color detection. It also outlines the role of the iris, pupil, lens and muscles in focusing light and allowing vision. For hearing, it notes sound waves enter the external ear and vibrate the middle ear bones to transmit signals to the inner ear and brain. Maintaining eye and ear health through regular checkups is important for these vital senses.
