Visual Field Testing for Eye Health

Visual Field Testing - Protecting Your Central and Peripheral Vision

Many people overlook the importance of checking their peripheral vision, yet visual field testing is one of the most critical assessments for detecting hidden eye and neurological conditions. Having a healthy visual field is essential not only for everyday tasks but also for maintaining your driver’s licence, as adequate peripheral vision is a legal requirement for safe driving.

What Is Visual Field Testing?

Your visual field refers to everything you can see—both central vision (straight ahead) and peripheral vision (side vision).
Visual field testing measures the full width and sensitivity of your vision, helping us identify any blind spots, vision loss, or abnormalities that may indicate underlying health issues.

This test is vital for diagnosing and monitoring conditions such as:

• Glaucoma

• Macular degeneration

• Optic neuritis

• Retinal diseases

• Brain tumours

• Stroke-related vision loss

• Neurological disorders

Because many of these conditions progress without early symptoms, regular testing ensures early detection and timely treatment.

Gold-Standard Testing with the ZEISS Humphrey Visual Field Analyzer

At Eyekonic Optometry, we use the ZEISS Humphrey Visual Field Analyzer (HFA)—the industry gold standard and the most trusted device worldwide for accurate perimetry testing. This advanced technology provides:

• Precise mapping of peripheral and central vision

• Early detection of glaucoma-related visual field defects

• Reliable monitoring for progressive diseases

• Fast, comfortable testing for all patients

With our state-of-the-art equipment, we can detect even the smallest changes in your visual field, ensuring your eye health is monitored at the highest level.

Protect Your Vision & Your Licence

Regular visual field assessments are essential for maintaining healthy eyesight and fulfilling driving requirements.
If you’re experiencing changes in your vision—or if you need a visual field test for your licence or medical review—our optometrists are here to help.                                     

How Visual Field Testing Works

Visual field testing is a quick, painless, and highly accurate way to assess both your central and peripheral vision. During the test, you will sit in front of the ZEISS Humphrey Visual Field Analyzer, the gold standard in perimetry testing, and press a button whenever you see a light stimulus. This allows us to map the sensitivity of your vision and identify any blind spots or reduced areas of awareness.

The ZEISS Humphrey Visual Field Analyzer provides reliable, detailed measurements that help detect early changes long before symptoms appear.

Why Visual Field Testing Is Important

The ZEISS Humphrey Visual Field Analyzer is essential in diagnosing and monitoring the progression of eye diseases, including:

• Glaucoma

• Macular degeneration

• Diabetic retinopathy

• Optic nerve disorders

• Neurological vision loss

For patients with glaucoma, the test tracks changes over time to help manage intraocular pressure and prevent progressive vision loss. For other retinal and neurological conditions, visual field testing helps evaluate functional changes in your sight and guides treatment decisions.

Regular Eye Exams & Preventive Care

Routine comprehensive eye exams are crucial for protecting your long-term eye health. Adults over 40 are recommended to have an eye examination every two years, or more frequently if you have higher risk factors such as:

• Family history of glaucoma

• Diabetes

• High myopia

• Previous eye injury

• Long-term steroid use

• Signs of visual field loss

Regular testing ensures that any issues are detected early—before permanent vision loss occurs.

Protect Your Vision with Early Detection

Visual field testing is a vital diagnostic tool that helps preserve your eyesight by identifying problems early and guiding timely treatment. Whether you need screening for glaucoma, assessment for neurological conditions, or monitoring for retinal disease, visual field testing gives you the best chance of maintaining healthy, functional vision.
