What role does the retina play in vision?

The retina plays a crucial role in vision by converting light into neural signals. It is located at the back of the eye and contains photoreceptor cells called rods and cones. These cells detect light and color, allowing us to see. When light enters the eye, it forms an image on the retina, and the photoreceptors then generate electrical signals in response to the light they absorb. These signals are transmitted to the brain through the optic nerve, where they are interpreted as visual images. This function of converting light into signals is essential for the entire visual process, making it the correct choice in this context.

Other options address different functions of the eye but are not the specific role of the retina. Regulating light entry refers more to the function of the iris and pupil. Forming images generally describes the overall process influenced by the lens and the retina but does not capture the unique role of the retina itself. Directing light towards the pupil pertains to the cornea and lens, which help focus light before it reaches the retina.
