What is the visual field?

The visual field is the area of space you perceive when you fixate on a point straight ahead. It includes central vision, which lets you see details, and peripheral vision, which lets you perceive what is happening to the sides without moving your eyes. This overall vision is essential for interacting safely with your environment.

A reduction in the visual field can make it harder to perceive obstacles, movements to the sides, or changes in the environment.
How is the visual field measured?The visual field is measured by detecting light or moving stimuli presented in different areas around a fixation point. The test evaluates your ability to perceive these stimuli, from central vision to peripheral vision.

Why is it important to know your visual field?

  • Detect a vision problem

    A decrease in the visual field can be a sign of certain eye conditions (glaucoma, neurological diseases, etc.).

  • Better navigate your surroundings

    Your visual field lets you perceive your surroundings as a whole and anticipate what is happening around you.

  • Driving safely

    Good peripheral vision is essential for detecting vehicles, pedestrians, and hazards on the sides and reacting quickly in traffic.

  • Monitoring your vision over time

    Regularly testing your visual field allows you to detect any changes early and adjust your care if necessary.
