    Study Notes

    Eye Anatomy

    • Pupil: The black circular opening in the center of the eye that regulates light intake, essential for focusing on objects.
    • Iris: The colored part of the eye that controls the diameter of the pupil, adjusting it in response to light intensity to manage light entry.
    • Sclera: The tough, white outer layer of the eye providing structural support and protection, facilitating eye movement.
    • Cornea: The transparent front layer covering the eye, crucial for protection and light refraction, preventing foreign substances from entering.
    • Lens: A flexible transparent structure located behind the pupil that adjusts its shape, allowing focus on objects at varying distances, similar to a camera lens.
    • Retina: A light-sensitive layer at the back of the eye containing photoreceptor cells (rods and cones), responsible for converting light into neural signals, enabling vision in color and black-and-white.
    • Optic Nerve: A bundle of nerve fibers transmitting visual information from the retina to the brain for interpretation and processing.
