The iris is the smooth, colored, and circular muscle surrounding the papillary opening, which is the central opening of the iris through which light enters the eye. The cochlea is a part of the inner ear that is involved in hearing, the fovea is a small depression in the retina that is responsible for sharp vision, and the blind spot is the area on the retina where the optic nerve leaves the eye, which is not sensitive to light.
