At what distance should near vision charts be held from the eye during assessment?

The appropriate distance for holding near vision charts during assessment is typically 14-16 inches from the eye. This distance is chosen because it closely resembles the average reading distance for most individuals, allowing for an accurate assessment of near visual acuity.

Holding the chart at 14-16 inches helps to accurately simulate real-life conditions when a person is reading or performing close work, such as reading text or using a computer. This distance ensures that the assessment reflects the patient's ability to see clearly and comfortably at typical reading ranges, providing meaningful insight into their near vision capabilities.

The specific choice of 14-16 inches is supported by common clinical practices and guidelines in optometry and ophthalmology, reinforcing its relevance in a theoretical testing situation for certification.
