Parts of The Eye

The eye is like a fluid filled ball, containing:

  • The Conjunctiva and Sclera

    The outer white part of the eyeball.

  • The Cornea

    The clear front opening which lets the light in.

  • The Iris

    The colored ring that determines the color of our eyes and how much light gets in.

  • The Lens

    The lens inside the eye (just behind the cornea and iris) which allows us to focus.

    A cataract is when the lens gets cloudy.

  • The Retina

    The nerve layer in the back of the eyeball, which captures the images we see and sends them to the brain via the optic nerve.

  • The Macula

    A special area of the retina used for reading and fine detail.

  • Vitreous Humor

    The clear, gelatinous substance filling the central cavity of the eye.

    This is like the eyes' circulatory system to bring in nutrients and wash out toxins.
