Question

Quizplus · Accepted Answer

The lens in the eye is responsible for refining and changing the focus of the light rays as they enter the eye. It does this by changing shape to bring objects into focus on the retina. The pupil is the opening in the center of the iris that regulates the amount of light entering the eye. The vitreous humor is a gel-like substance that fills the eyeball and helps maintain its shape, while the retina is the layer of cells at the back of the eye that contains the photoreceptor cells responsible for converting light into electrical signals that the brain can interpret as vision.
