A person with vision defect ‘Myopia’ can see

Year Asked: 2015

A
nearby objects clearly
B
Distant object clearly
C
Nearby as well as distant objects clearly
D
neither nearby nor disant objects clearly.

Correct Answer

A. nearby objects clearly

Detailed Explanation

The correct answer is A) nearby objects clearly. In myopia, or short-sightedness, the eyeball is too long or the cornea/lens is too strongly curved, so the image of a distant object forms in front of the retina. Near objects bring the image back onto the retina, so they look sharp, while distant objects look blurred.

  • B is wrong: Seeing distant objects clearly is the normal eye's ability. The myopic eye loses exactly this.
  • C is wrong: A myope cannot focus on both at once without correction. Seeing both clearly is the normal (emmetropic) state.
  • D is wrong: Near vision remains intact in myopia, so nearby objects are seen clearly.

The defect is corrected with a concave (diverging) lens of negative power, which moves the focal point back onto the retina. This is a standard Prelims topic under human eye and optics in General Science. For Mains, it also links to basic health awareness and the role of eye-care programmes such as the National Programme for Control of Blindness.

Trap: Candidates often mix up myopia with hypermetropia, where distant vision is clear and near vision is blurred, and which is corrected with a convex lens.
