Identify the wrong description of the below figures.
- A I represents far - sightedness
- B II correction for short-sightedness
- C III represents far - sightedness
- D IV correction for far - sightedness
Answer & Solution
Correct Answer
(A) I represents far - sightedness
Step-by-step Solution
Detailed explanation
In first figure, the parallel rays are converging at a point before the retina. So, the person is suffering from near-sightedness.
