The Snellen test is best described as which type of assessment?

• A. Hearing test.
• B. Vision test.
• C. Blood pressure measurement.
• D. Urinalysis.

Answer: (B)

Visual acuity is being assessed. The Snellen chart measures how clearly you can see at a distance by having you read letters from a set distance to determine the smallest line you can identify. Results are written as a fraction like 20/20: the top number is the testing distance, and the bottom shows the distance at which a person with normal vision can read that line. This directly evaluates how well your eyes focus and resolve detail at distance, which is why it’s classified as a vision test. It’s not a hearing test, blood pressure measurement, or urinalysis.
