Humphrey Visual Field Test

The Humphrey Visual Field Test is a common eye exam used to measure a person's full visual field—the total area they can see when looking straight ahead. During the test, you look into a device and focus on a central point while lights of different sizes and brightness appear in various areas. You press a button each time you see a light. This helps detect and monitor conditions like glaucoma or neurological issues by mapping areas of vision loss or narrowing. It’s a precise, non-invasive way to assess the health of your visual pathway.
