Solution
The correct option is C Astigmatism
We can use cylindrical lens in Astigmatism as here → either the front surface of your eye (cornea) or the lens, inside your eye, has mismatched curves. Instead of having one curve like a round ball, the surface is egg shaped, thus here we use cylindrical lens Hence option 'C' is correct.
