Myopia is a defect in human vision where an image of a

Options

  1. Anearby object is focused beyond the retina.
  2. Bnearby object is focused before the retina.
  3. Cdistant object is focused before the retina.
  4. Ddistant object is focused beyond the retina.

Correct answer

C. distant object is focused before the retina.

Step-by-step solution

Due to myopia the eyes can see nearby objects clearly but cannot see distant objects. This defect is caused due to the formation of the image of a distant object in front of the retina. An eye suffers from the defect of myopia due to the following two reasons 1. Abnormally long eyeball 2. Abnormally high convexity of the eye lens This defect is corrected by using spectacles having suitable concave lenses. The concave lenses diverge the light rays, so the image is formed exactly on the retina.
