Frisby stereo test does not require glasses and incorporates true depth into its design. Which statement best describes it?

• A. Does not require glasses and incorporates true depth into its design
• B. Requires red-green glasses
• C. Uses random dot patterns
• D. Measures color vision

Answer: (A)

This test measures stereo vision using real depth cues without the need for glasses. It uses transparent plates with patterns placed at different physical depths, so the depth difference is real in space rather than created by an image on a screen. Because the depth cue is actual, no red–green glasses, polarized filters, or color cues are required. This distinguishes it from tests that rely on random dot patterns or color vision assessments. So the statement describing no glasses and true depth in the design best captures what Frisby stands for.
