How many inches from the eye should near vision charts be held?

Near vision charts are typically held 14-16 inches from the eye to ensure optimal viewing conditions for assessing near visual acuity. This distance is based on standard practices that help simulate the distance at which individuals typically read comfortably in everyday situations.

Holding the chart within this range allows for an appropriate level of detail and clarity, accommodating the average working distance for reading or close-up tasks. It balances comfort and accuracy, minimizing strain on the eyes while providing a reliable measurement for visual acuity testing. This standard distance is also aligned with human anatomy and visual performance, ensuring that measurements taken are representative of what patients experience in daily activities.
