The light-sensitive cells found in the retina of the eye are cones and rods. Cones are responsible for color vision and function best in bright light, allowing us to perceive fine detail and a range of colors. Conversely, rods are more sensitive to light and enable vision in low-light conditions, but they do not contribute to color perception. Together, these cells play a crucial role in our ability to see across different lighting conditions and perceive a spectrum of colors.

The other options do not represent light-sensitive cells. Pupils and lenses are anatomical structures that help control the amount of light that enters the eye and focus light on the retina, but they are not photoreceptive. Corneas and scleras are parts of the eye that help protect it and maintain its shape, while retinal ganglion cells are not light-sensitive cells themselves but rather transmit visual information from the photoreceptors (cones and rods) to the brain. Thus, the correct answer highlights the essential types of photoreceptors in the retina that facilitate vision.
