Presbyopic correction in an old patient is:
Show Hint
Near add rises with age and tops out around this plus value in the elderly.

- +1 D
- +2 D
- +3 D
- +4 D
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Reading vision depends on accommodation, which steadily declines with age; presbyopia is corrected by adding a plus lens to make up the deficit.
Step 2: The required add is graded by age - roughly $+1\,D$ in the early forties, climbing through $+1.5$ to $+2\,D$ in the fifties.
Step 3: Once accommodation is nearly exhausted in old age, the add plateaus at its highest practical value, conventionally taken as $+3\,D$.
Step 4: A $+4\,D$ add is not a standard presbyopic prescription, so for an elderly patient the correct near add is $+3\,D$.
\[\boxed{+3\,D}\]
