      Question

      Persons suffering from myopia are advised to use –

      A convex lens Correct Answer Incorrect Answer
      B concave lens Correct Answer Incorrect Answer
      C piano-convex lens Correct Answer Incorrect Answer
      D plano-concave lens Correct Answer Incorrect Answer

      Solution

      A concave lens is used to correct short-sightedness (myopia). In myopia, images are formed in front of the retina, resulting in a blurred image. This occurs when the eye is relatively too long or the refractive powers of the cornea and lens of the eye are relatively too strong.
