What is the first step in the standard visual acuity testing sequence?

• A. Form Recognition
• B. Hand Motion
• C. Light Projection
• D. Light Perception

Answer: (A)

Starting with form recognition sets a practical baseline for acuity testing by asking whether the patient can identify recognizable shapes or large optotypes at the test distance. If they can reliably name the form, you can progressively present smaller or more challenging forms to pinpoint the acuity threshold. This approach moves from meaningful, real-world recognition to finer discrimination, which is what acuity testing aims to quantify. Lower-level detection tasks—like sensing light, detecting light direction, or noticing hand movement—measure basic vision presence but don’t provide a usable acuity value, so they’re typically used only when form recognition can’t be established.
