Explanation:
Detailed explanation-1: -The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
Detailed explanation-2: -What is the iris? The iris is a thin, round, highly pigmented circular membrane between the cornea and the lens. It divides the eye’s anterior chamber into an anterior and posterior chamber. It has a center opening, called the pupil.
