The inside layer of the eyeball that contains rods or cones and focuses an image for recording is the?

• A. Cornea
• B. Lens
• C. Retina
• D. Sclera

Answer: (C)

Photoreceptors reside in the retina, the light-sensitive layer at the back of the eye. Rods detect light intensity and motion, cones detect color, and together they convert incoming light into electrical signals that the brain interprets as an image. Light is focused onto the retina by the cornea and lens, but the retina itself is where the image is recorded. The cornea and lens do the focusing, while the retina handles detection and recording. Sclera is the protective outer layer. That combination makes the retina the correct inside layer containing rods or cones and responsible for recording the image.
