Model Answer

In a myopic eye, the image of a distant object forms in front of the retina due to the following structural reasons:

  1. Excessive curvature of the eye lens — This increases the converging power of the lens, causing light rays to focus before reaching the retina.
  2. Elongation of the eyeball — The eyeball becomes too long, so the retina lies farther back than the focal point.

Explanation

Examiners specifically look for these two causes as stated in the NCERT textbook. Write both clearly with a brief reason for each — just naming them without explanation may not fetch full marks. Avoid writing about correction (concave lens) unless asked; this question only asks for structural reasons.
