The Eye

The pupil is the black part of your eye right in the middle; the Iris is the colored part of your eye (e.g. green, blue, brown) that surrounds the pupil. The Sclera is the white of your eye that surrounds the Iris. Plica semilunaris is the crescent-shaped fold located in the medial corner of the eye. The Lacrimal caruncle is the small, pink, globular nodule that sits on top of the Plica semilunaris. It is made of skin covering sebaceous and sweat glands.
