Question
Farsightedness (Hypermetropia) and Nearsightedness (Myopia).
✓
Answer
Farsightedness:
- In hypermetropia, a human eye can see distant distinctly but is unable to see nearby objects clearly.
- In this case, the image of a nearby object would be formed behind the retina.
- This defect can be corrected using a convex lens of appropriate power.
Nearsightedness:
- In myopia, a human eye can see near objects distinctly, but is unable to see distant objects clearly.
- In this case, the image of a distant object is formed in front of the retina.
- This defect can be corrected using a concave lens of appropriate power.
