A client has undergone the Snellen eye chart test and has 20/40 vision. Which of the ff is true for this client?
- A. The client sees letters at 20 feet that others can read at 40 feet
- B. The client sees letters at 40 feet that others can read at 20 feet
- C. The client sees colors at 20 feet that others can see at 40 feet
- D. The client sees colors at 40 feet that others can see at 20 feet
Correct Answer: A
Rationale: In the Snellen eye chart test, the first number (20) represents the distance at which the client is standing from the chart, while the second number (40) represents the distance at which a person with normal vision can read the same line on the chart. A person with 20/40 vision can see letters at 20 feet that a person with normal vision can see at 40 feet. This means that the client's vision is below the standard for normal vision, indicating that they may need corrective lenses to improve their visual acuity.
