What is your visual field of view when using central vision?

• A. 60-90 degrees.
• B. 30-40 degrees.
• C. 5-15 degrees.
• D. 120-160 degrees.

Answer: (B)

Central vision is the narrow, high-acuity part of vision you use to see detail when you’re looking directly at something. It can resolve fine detail across roughly 30 to 40 degrees of the visual field around your gaze. Within this zone you can read instruments, recognize small details, and perform precise tasks. Outside of about 40 degrees, acuity drops and you’re mostly relying on peripheral vision for awareness and motion detection. So, the best answer is 30–40 degrees because it reflects the range where you can still see detail clearly, while more peripheral areas provide less detail. The other ranges describe too broad or too narrow fields for central, high-resolution vision.
