Question

Quizplus · Accepted Answer

The retina is the light-sensitive innermost layer of tissue at the back of the eyeball. It contains photoreceptor cells that convert light into neural signals that are transmitted to the brain for visual processing. The iris is a ring of muscle tissue that controls the size of the pupil and regulates the amount of light that enters the eye. The cornea is a clear, dome-shaped structure that covers the front of the eye and helps to focus light. The ciliary body is a ring of muscle that adjusts the shape of the lens to focus on objects at different distances.
