Snellen testing is a vision acuity test to document the ability to see at a distance.

Explanation:
Snellen distance vision testing uses a fixed testing distance to measure how clearly you can see at a distance. The standard distance in the familiar Snellen chart is 20 feet. This consistent distance lets clinicians compare acuity reliably, with 20/20 indicating normal vision at that distance. The other options aren’t the standard distance used for this test (though some places use a metric equivalent like 6 meters). So, the 20-foot distance is the one that makes Snellen acuity measurements meaningful and comparable.
