During vision screening, at which distance should near vision be assessed?

  1. 10-12 inches

  2. 14-16 inches

  3. 18-20 inches

  4. 20-24 inches

The correct answer is: 14-16 inches

The assessment of near vision typically occurs at a distance of 14-16 inches, which is considered optimal for accurately evaluating a person's ability to see objects up close. This distance allows for a comfortable viewing range where most individuals can read text or discern details clearly without strain. Assessing near vision at this range helps to effectively identify issues such as presbyopia or other refractive errors that may affect near vision. Other options suggest either too close or too far a distance for optimal near vision assessment. Distances that are significantly shorter or longer may not provide a true reflection of the patient's near vision capabilities, leading to inaccurate results.
