Question

To restore clear vision in persons whose size of the eyeball has reduced, he/she is suggested to use suitable

• A. Converging lens
• B. Diverging lens
• C. Bifocal lens
• D. Cylindrical lens

Hint:

Hypermetropia → Use convex (converging) lens.

Answer 1

The Correct Option is A

Concept: A reduced eyeball size causes hypermetropia (long-sightedness), where distant objects are clear but nearby objects are blurred. Explanation:

• In hypermetropia, the image forms behind the retina.
• A converging (convex) lens converges light rays before they enter the eye.
• This helps form the image on the retina, restoring clear vision.

Conclusion: A converging (convex) lens is used to correct vision when the eyeball size is reduced.
