At what distance should near vision charts be held for optimal evaluation?

• A. 10-12 inches
• B. 12-14 inches
• C. 14-16 inches
• D. 16-18 inches

Answer: (C)

For optimal evaluation of near vision charts, they should be held at a distance of 14-16 inches. This distance is considered standard because it closely mimics the typical reading distance for most individuals. Holding the chart within this range allows for clear legibility and effective assessment of one's near visual acuity. When charts are positioned at this distance, it ensures that the eye's accommodation is engaged appropriately, allowing for an accurate measurement of near vision capabilities. Distances outside of this range may not provide the same clarity or reliability in determining how well someone can see at a normal reading distance.
