VISUAL FIELD TESTING
Helping detect changes before you notice them.
Visual field testing measures your peripheral (side) vision and helps us detect and monitor conditions that can affect how your eyes function. It's an important part of diagnosing and managing diseases such as glaucoma, often before you notice any changes yourself.
Visual Field Testing
What is visual field testing?
Visual field testing is a simple, non-invasive test that measures how well you can see beyond your central vision. While you're looking straight ahead, the test checks how well you detect small lights appearing in different areas of your peripheral vision.
Because many eye conditions develop gradually without obvious symptoms, visual field testing allows us to identify subtle changes that may otherwise go unnoticed.
Why do we use visual field testing?
At Lens Lounge, visual field testing helps us understand how your eyes are functioning, not just how they look.
It plays an important role in:
Detecting glaucoma
Monitoring glaucoma progression
Assessing neurological conditions that affect vision
Investigating unexplained vision changes
Comparing results over time
When combined with your REVO OCT scan, visual field testing provides a more complete picture of your eye health.
What does this mean for you?
Earlier detection
Many conditions affecting your peripheral vision develop gradually and without noticeable symptoms.
Visual field testing helps us identify these changes early, often before they begin affecting your everyday vision.
Better monitoring
Your results are stored so we can compare future tests against previous ones.
This helps us identify even subtle changes over time and make informed decisions about your ongoing care.
Comfortable and straightforward
The test is completely non-invasive and painless.
You'll simply look at a central target and press a button whenever you notice a light appear.
Although the test requires concentration, we'll guide you through it and make sure you're comfortable throughout.
More informed care
When we combine visual field testing with your REVO OCT scan and comprehensive eye examination, we gain a much clearer understanding of both the structure and function of your eyes.
This allows us to provide more personalised care and greater confidence in our clinical decisions.
Frequently Asked Questions
-
Not at all. Visual field testing is completely painless and non-invasive. Nothing touches your eye, and you'll simply respond whenever you see small lights during the test.
-
The test usually takes around 5–10 minutes, depending on the type of assessment being performed. We'll explain everything beforehand and guide you through each step.
-
Visual field testing helps us detect and monitor conditions that can affect your peripheral vision, particularly glaucoma. It may also be recommended if you're experiencing vision changes or if we need additional information about your eye health.
-
Visual field testing is recommended when clinically appropriate. Unlike your REVO OCT scan, not every patient requires a visual field assessment. If we believe it will provide valuable information about your eye health, we'll explain why before performing the test.
-
That's completely normal. The test is designed to measure your vision, not your reaction speed or ability to get every answer right. Simply do your best, and the machine accounts for normal variations throughout the test.
The REVO OCT shows us how your eyes are structured. Visual field testing shows us how your vision is functioning. Together, they provide a more complete picture of your eye health.
