The colored part of the eye is the

• A. Cornea
• B. Lens
• C. Choroid coat
• D. Iris

Answer: (D)

The iris is the colored part of the eye that surrounds the pupil. It contains pigment that gives the eye its color and muscles that adjust the pupil size to control how much light enters the eye. When it's bright, the sphincter pupillae contracts to make the pupil smaller; in dim light, the dilator pupillae relaxes to widen the pupil. The cornea is the clear front surface that helps focus light, the lens sits behind the iris to focus, and the choroid coat is the dark vascular layer that nourishes the retina and absorbs excess light.
