What is the standard distance used for testing near visual acuity?

1. At least 5 feet

2. The distance indicated on the near card

3. 6 meters

4. 10 feet

The correct answer is: The distance indicated on the near card

The standard distance for testing near visual acuity is typically specified as the distance indicated on the near card. This distance is often standardized at 14 to 16 inches (approximately 35 to 40 cm) from the patient's eyes when using a near vision card. This proximity allows for optimal visual clarity and accuracy in measuring how well a patient can perceive detail at a close range, which is particularly relevant for activities such as reading. Choosing the distance indicated on the near card allows for consistency and reliability in testing near vision across different clinical settings. Using a standardized near card ensures that the test is conducted under conditions that are controlled and replicable, leading to results that can be accurately compared across different assessments and aiding in the diagnosis of any potential visual impairments. Other distances provided, such as 5 feet, 6 meters, or 10 feet, are typically associated with testing distance visual acuity rather than near visual acuity. These distances may compromise the effectiveness of the near vision assessment, as they are not suited for evaluating close-up tasks where clear vision at a shorter range is essential. Thus, relying on the specific distance indicated on the near card is crucial for precise and appropriate near visual acuity measurement.
