What is the recommended distance used for assessing distance acuity?

  1. 10 feet or 3 meters

  2. 15 feet or 4.5 meters

  3. 20 feet or 6 meters

  4. 25 feet or 7.5 meters

The correct answer is: 20 feet or 6 meters

The recommended distance used for assessing distance acuity is 20 feet or 6 meters. This distance is standard in ophthalmic practice for measuring visual acuity as it allows for accurate comparisons between different individuals and across different eye care settings. It is essential to use a consistent distance to obtain reliable and comparable results when assessing a patient's visual acuity.
