  1. Question 1

    Q1. A convex (converging) lens is used to correct which vision defect?

    • A) Astigmatism
    • B) Myopia (short-sightedness)
    • C) Hypermetropia (long-sightedness)
    • D) Colour blindness

    Answer: Hypermetropia (long-sightedness)

    Explanation: Hypermetropia (long-sightedness) occurs when the eyeball is too short or the lens too flat, causing parallel light rays from distant objects to converge at a focal point behind the retina; a convex (converging) lens placed in front of the eye adds refractive power, shifting the focal point forward.
