Has blood vessels which nourish surrounding tissues. Has melanocytes (cells that produce melanin). Melanin absorbs the excess light which helps to keep the inside of the eye dark.

Allows us to see objects near and far. Adjusts shape to facilitate focusing (accomodation)

Colored part of the eye that is a smooth muscle. This controls the amount of light entering the eye. In dim light, the muscles of this part causes the pupil to dilate. In bright light, the muscles of this part cause the pupil to constrict

Fluid between the cornea and the lens that nourishes both the cornea and the lens. This fluid leaves through the veins of the eye and maintains the shape of the front of the eye.

Inner wall of the eye that contains photoreceptors (convert images into impulses). This part of the eye contains both cones (light sensitive structures; allows for color discrimination, functions under bright lighting, and gives you sharp/detailed vision) as well as rods (light sensitive structures; functions under dim lighting, and gives you peripheral vision)

Exits the back of your eye and sends impulses from your retina to your brain

Transparent, jelly like fluid in the posterior (back) cavity. Supports the internal parts of the eye & helps it to maintain its shape
