Question

The defect due to which a person is not able to see the distant objects clearly is called ______.
1. Hypermetropia
2. Cornea
3. Myopia
4. Cataract 

Answer 1

Correct Answer - Option 3 : Myopia

The correct answer is Myopia.

• Myopia is an eye disorder.
• In myopia, the eyeball is too long for the normal focusing power of the eye. As a result, images of distant objects appear blurred.
• The nearsighted (myopic) eye converges rays from a distant object in front of the retina thus, they are diverging when they strike the retina, producing a blurry image.
• A concave lens (minus powered) is placed in front of a myopic eye, moving the image back to the retina and clarifying the image.

• Hypermetropia is a condition in which the individual can focus only on faraway objects which is why it is called longsightedness. 
• A cataract is a condition in which there is a decrease in the vision due to the clouding of the lens.
• The cornea is the transparent part of the eye that covers the front portion of the eye.
  • It covers the pupil, iris, and anterior chamber.
  • The cornea's main function is to refract or bend, light.
