Cornea | MCQs

Explanation

Eduard Zirm performed the world's first successful human cornea transplant in 1905.

The operation restored vision to a man who had been blinded by a chemical burn.

Explanation

• The lens is responsible for refracting (bending) light to focus it onto the retina.
• It changes shape to adjust the focal length, allowing the eye to focus on objects at varying distances.
• This enables all light rays entering the eye to meet at a single point on the retina, creating a clear image.

Explanation

• The cornea is the transparent, dome-shaped surface at the front of the eye.
• It helps focus light by bending (refracting) it towards the lens.
