Explanation

The iris is the colored part of the eye containing pigments (melanin) that determine eye color - brown, blue, green, etc. The amount and type of melanin in the iris create these variations. The cornea (A) is the transparent outer layer, choroid (B) is the vascular layer behind the retina, and vitreous body (D) is the jelly-like substance filling the eye.
