The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Astigmatism occurs due to irregular or uneven curvature of lens. It is an optical defect in which vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. People with undetected astigmatism often have blurred vision which can be associated with fatigue and eyestrain. It is treated with cylindrical lenses.Thus, the correct answer is option B.
