Which transparent part of the eye covers the lens, iris, and pupil and helps focus light into an image?

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

Answer: (B)

The cornea is the transparent front surface of the eye that covers the iris, pupil, and the lens behind it. Its clear, curved shape lets light enter and provides most of the eye’s focusing power by bending incoming light toward the lens, helping to form a sharp image on the retina. The lens then fine-tunes that focus, especially for objects at different distances. The iris controls how much light enters by adjusting the pupil size, and the retina sits at the back of the eye to receive the focused image and send signals to the brain.
