By about 12 months of age, FPCL methods typically yield acuity around which Snellen value?

• A. 20/20
• B. 20/50
• C. 20/70
• D. 20/100

Answer: (B)

Infants’ visual acuity grows rapidly in the first year, and FPCL is used to estimate acuity in preverbal children by showing a pattern and watching whether they reliably look toward it. By about 12 months, the level of detail they can resolve on this method typically corresponds to about 20/50 Snellen. This reflects normal maturation of the visual system for that age with this testing approach. A 20/20 result would be unusually sharp for this age on FPCL, while 20/70 or 20/100 would suggest more delayed development or a potential issue.
