Thanks...this site is the best!!
Yes, you are correct! The lens, iris, and cornea are three structures in the eye that help to focus light rays. The lens is a transparent, flexible structure located behind the iris and is responsible for fine-tuning the focusing of light onto the retina. The iris is the colored part of the eye and acts as a diaphragm, adjusting the size of the pupil to control the amount of light entering the eye. The cornea is the clear, dome-shaped surface on the front of the eye that helps to focus light by refracting it.
