Which test uses color plates to assess color vision when FALANT is unavailable?

• A. Pseudoisochromatic plates
• B. Jaeger charts
• C. FALANT
• D. AFVT

Answer: (A)

Color-plate tests use colored-dot plates to reveal color discrimination ability. A person with normal color vision can pick out a figure or number formed by color differences, while someone with a color deficiency struggles to see it, signaling the deficiency. When the lantern-style FALANT isn’t available, these pseudoisochromatic plate tests are the practical alternative because they’re quick, require minimal equipment, and effectively screen for common red-green color vision problems. Jaeger charts assess near vision (reading) and aren’t about color, and the AFVT isn’t a plate-based color test, so they don’t serve as substitutes for color-vision screening with plates.
