What is the field of vision for central vision?

Central vision is critical for tasks that require focused, detailed eyesight, such as reading, recognizing faces, and other activities where clarity is paramount. The field of vision for central vision typically ranges from about 30 to 40 degrees. This area is where we have the highest acuity and can perceive fine details sharply.

Understanding the field of vision is essential for aviation crew members, as it directly impacts their ability to monitor instruments and the environment effectively. While peripheral vision allows for a broader awareness of surrounding movements and changes, it is the central vision that provides the clarity necessary for critical tasks. The other options exceed this range, where peripheral vision comes into play rather than central vision, which is why they do not accurately reflect the correct scope for central vision.
