Answer 1

Answer: (A)

Astigmatism

Astigmatism is a refractive error, meaning it is not an eye disease or eye health problem; it's simply a problem with how the eye focuses light. In an eye with astigmatism, light fails to come to a single focus on the retina to produce clear vision. Instead, multiple focus points occur, either in front of the retina or behind it (or both). Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape. Astigmatism usually causes vision to be blurred or distorted to some degree at all distances. Symptoms of uncorrected astigmatism are eye strain and headaches, especially after reading or other prolonged visual tasks.

So the correct option is 'astigmatism'.
