What Is a Visual Field Test?
Your visual field includes everything you can see without moving your eyes — your central and side vision.
A visual field test maps this area to identify blind spots, reduced sensitivity, or neurological changes that could indicate eye or brain disorders.
Here’s how it works:
-
You’ll focus on a central target while small lights flash in your peripheral vision.
-
Each time you see a light, you’ll press a button.
-
The test maps your field of vision for each eye separately.
-
The full process takes about 10–20 minutes and provides an instant visual map for your doctor to review.
