In the human eye, the defect of vision where the eyeball is too long or the cornea is too curved, causing light to focus in front of the retina, is called:
A. Astigmatism
B. Myopia (Nearsightedness)
C. Presbyopia
D. Hypermetropia (Farsightedness)
Answer: Option B
Solution (By JKExamLibrary)
Myopia, or nearsightedness, is a refractive error where distant objects appear blurry, but near objects are clear. It occurs when the eyeball is elongated (axial myopia) or the cornea/lens is too curved (refractive myopia), causing light rays from distant objects to focus in front of the retina instead of directly on it. It is corrected using a concave (diverging) lens. Hypermetropia is the opposite, corrected with a convex lens.
