Jaeger testing is a visual acuity test to document vision ability at a normal reading distance.

• A. Near distance
• B. Normal reading distance
• C. Far distance
• D. Intraocular distance

Answer: (B)

Jaeger testing measures near visual acuity—the ability to read small print at the distance at which people usually do close-up tasks like reading. The chart is held at a close, everyday reading distance, typically about 14 inches (roughly 35 cm) from the eye. This distance corresponds to normal reading distance, which is why the option describing normal reading distance is the best fit. If you were testing at a far distance, that would be a different kind of acuity test (distance vision). The idea of “near distance” is less precise in clinical terms, and intraocular distance isn’t a measure used for acuity testing.
