What part of the eye causes blindness?

There is no one single part of the eye that causes blindness. Blindness can be caused by a variety of conditions that can damage different parts of the eye, including:

- The cornea, which is the clear, dome-shaped outer layer of the eye

- The lens, which is the transparent structure behind the cornea

- The retina, which is the light-sensitive tissue at the back of the eye

- The optic nerve, which carries visual information from the eye to the brain

Damage to any of these structures can interfere with the eye's ability to see, leading to blindness.
