Why Visual Field Testing Is an Important Part of Eye Care

Good vision is not limited to seeing clearly straight ahead. Your field of vision also includes what you can see around you, including peripheral areas.

Visual field testing is one of the diagnostic tools that may be used during an eye examination to evaluate different areas of a person's vision.

What Is a Visual Field Test?

A visual field test measures how well you can see objects or light stimuli in different areas of your visual field.

The test can provide information about peripheral vision that may not be identified through a standard eye chart.

Why Is Peripheral Vision Important?

Peripheral vision helps you notice objects and movement outside your direct line of sight. It can be especially important for activities such as walking, driving, and navigating your surroundings.

Changes in the visual field may not always be immediately noticeable during everyday activities, which is one reason visual field testing can be useful when clinically appropriate.

Visual Field Technology at Tatum Eyecare

Tatum Eyecare uses the Humphrey FDT Visual Field Screener for an initial screening of the visual field. The practice also uses the Haag-Streit Octopus Visual Field Analyzer for more detailed full-threshold visual field testing when indicated.

These technologies can provide additional information to an eye doctor when evaluating visual field changes.

Visual Field Testing and Comprehensive Eye Care

Visual field testing is just one part of a comprehensive eye examination.

Depending on the patient, an eye care professional may also perform refraction, retinal imaging, OCT scanning, eye pressure measurement, slit-lamp examination, and other tests.

A complete examination allows the doctor to consider multiple aspects of vision and eye health rather than relying on one test.

To help you separate fact from fiction, we are debunking the five most common myths about contact lenses . Whether you are a first-time user or considering making the switch from glasses, this article will give you the clarity you need. Myth 1: Contact Lenses Can Get Stuck Behind Your Eye One of the most pervasive myths is the fear that contact lenses can slip behind your eye and get stuck. This belief is entirely false, as it is anatomically impossible for a lens to move behind your eyeball.

If your lens feels displaced, it is likely lodged under your upper eyelid, which can be easily resolved by gen...
