Explain
Short Note

Write scientific reason.

Adults need bifocal lens spectacle.

Advertisements

Solution

  1. The ability of the ciliary muscles near the eye lens to change the focal length of the lens decreases with age.
  2. As a result, sometimes adults suffer from both nearsightedness and farsightedness.
    Therefore, adults need bifocal lens spectacle.
Concept: Convex Lens
  Is there an error in this question or solution?
