Q1When the cornea is not spherical in shape, the defect of vision in this eye is called:
Explanation
Astigmatism occurs when the cornea or lens does not have a uniform spherical curvature, so light is focused unevenly and vision may appear blurred or distorted. Myopia is short-sightedness, where distant objects are not seen clearly. Hypermetropia is long-sightedness, where near objects are difficult to see clearly. Cataract is clouding of the eye's lens, not a defect caused by a non-spherical cornea. Since the stem specifically mentions the cornea not being spherical, astigmatism is the correct answer.
