Question

Quizplus · Accepted Answer

The lens is primarily responsible for focusing light onto the back of the eye. It does this by changing shape to adjust the amount of refraction (bending) of the incoming light. The cornea also plays a role in focusing light, but to a lesser extent than the lens. The fovea is a small, central area of the retina responsible for high acuity vision, and the retina itself contains the light-sensitive cells that convert light into electrical signals that are sent to the brain for processing.
