Question

Quizplus · Accepted Answer

The correct sequence of structures involved in vision is from the cornea to the lens to the retina. The cornea and lens both refract and focus incoming light onto the retina, which contains the photoreceptor cells (rods and cones) that convert the light into electrical signals that are sent to the brain for processing. The sclera is the white outer layer of the eye that provides support and protection but is not directly involved in vision.
