Counting fingers is an accurate visual acuity measurement.

Counting fingers is an accurate visual acuity measurement.

• A. False
• B. True
• C. Not Reliable
• D. Depends on Conditions

Answer: (A)

Counting fingers is not an accurate visual acuity measurement. True acuity is quantified with standardized charts (like Snellen or LogMAR) that give a specific numerical value. Counting fingers is a qualitative, functional assessment used when the person cannot read letters, and it lacks standard distance, lighting, and scoring consistency. Because examiner technique, lighting, distance, and patient understanding can all influence the result, CF results vary and don’t provide a precise acuity value. In low-vision contexts, CF may be noted to indicate very limited vision, but it isn’t a reliable substitute for formal acuity measurements.
