    The human eye is a complex organ responsible for vision and consists of several key parts:<div>
    </div><div>1. Cornea: The transparent outer layer that covers the front of the eye and helps to focus light onto the retina.</div><div>
    </div><div>2. Iris: The colored part of the eye that regulates the amount of light entering the eye by adjusting the size of the pupil.</div><div>
    </div><div>3. Pupil: The black circular opening in the center of the iris through which light enters the eye.</div><div>
    </div><div>4. Lens: A clear, flexible structure located behind the iris that helps to further focus light onto the retina.</div><div>
    </div><div>5. Retina: The innermost layer of the eye that contains photoreceptor cells (rods and cones) responsible for detecting light and transmitting visual information to the brain via the optic nerve.</div><div>
    </div><div>6. Optic nerve: The bundle of nerve fibers that carries visual information from the retina to the brain for processing.</div><div>
    </div><div>7. Vitreous humor: A clear gel-like substance that fills the space between the lens and the retina, helping to maintain the shape of the eye and transmit light to the retina.</div><div>
    </div><div>These parts work together to capture, focus, and transmit light signals to the brain, allowing us to perceive the world around us visually.</div>
