Answers (1)

Explanation:-

Myopia 

  • The image of a distant object is formed in front of the retina due to the eye being too long or too strong a refractive power. This condition causes difficulty in seeing objects at a distance.
  • Correction: Myopia is corrected with a concave (diverging) lens, which diverges the light before it enters the eye. This ensures the image forms on the retina.

Hypermetropia

  • The image of a near object is formed behind the retina due to the eye being too short or too weak a refractive power. This leads to difficulty focusing on close objects.
  • Correction: Hypermetropia is corrected with a convex (converging) lens, which focuses the light on the retina by converging the rays before they enter the eye.
