Which of the following is not a reason for blindness?

Which of the following is not a reason for blindness? Correct Answer Low blood supply to the cornea

Cornea does not receive blood supply at all thus it cannot be a reason for blindness. The cornea simply a covering of the lens and protects it. The focal length of the lens is changed by the ciliary muscles and these muscles receive blood supply. Even if the ciliary muscles stop receiving blood, it will result in conditions like myopia, hpyermetropia etc.
