Which structure of the eye is correctly matched with its function? a. cornea – regulates the amount of light entering the eye b. lens – protects the eye c. iris – controls the pupil d. pupil – focuses light on the retina?

Answer;

C. iris – controls the pupil

Explanation;

-Iris  is the diaphragm consisting of thin overlapping plates that can be adjusted to change the diameter of a central opening(pupil) .

-Cornea  is the clear/transparent, anterior part of the eyeball covering the iris, pupil, and anterior chamber that functions to refract (bend) light to focus a visual image(admits light into the eye).

-Lens  is a biconvex, transparent, flexible, a vascular structure that allows precise focusing of light onto the retina, composed of epithelium and lens fibers( lens epithelium, lens fibers)(Cloudy-Cataract;changes shape to help focus images on the retina). Pupil  is black adjustable circular opening in the center of the iris through which light passes as it enters the eye.
