Question

Quizplus · Accepted Answer

The clear membrane just in front of the iris through which light first passes is the cornea. The cornea is responsible for the majority of the eye's focusing power and acts as a protective barrier for the eye. The retina is located at the back of the eye and contains photoreceptor cells that detect light. The lens is located directly behind the iris and helps to focus incoming light onto the retina. Rods are one type of photoreceptor cell found in the retina that are responsible for detecting light in low levels of illumination.
