As your local optometrist in Glendale Heights, iDoctor delivers clarity, comfort, and peace of mind close to home.

What Is Visual Field Testing and How Does It Work?

Visual field testing (or perimetry) is a painless, non-invasive way of checking how much you can see—both straight ahead and to the sides. While you may notice blurry vision or trouble focusing, loss in side vision often goes undetected at first. That’s why this test is critical: it identifies silent changes that even you may not recognize.

During a visual field test at iDoctor:

• You’ll sit comfortably with your chin in a rest, covering one eye at a time.
• A series of tiny lights will appear in different locations inside a dome or bowl-shaped device. Your job? Press a button any time you spot a flash.
• The instrument records every response, giving Dr. Sayed a detailed map of your visual sensitivity—both central and peripheral—in just 5 to 15 minutes per eye.

There are two main types:

• Static perimetry: Lights in various set positions blink off and on in random order. Great for detecting even mild vision loss from glaucoma or other eye problems.
• Kinetic perimetry: Lights move from outside toward the center, showing the boundary of what you can see. Useful in some neurological conditions.

Most people are surprised at how easy this is—no drops, no contact, and no discomfort. Our skilled team, including certified technicians like Hannah and Allyson, will support you to ensure you’re relaxed and get the most accurate results possible.

Why Visual Field Testing Matters: Local Benefits in Glendale Heights

Here’s why visual field testing at iDoctor in Glendale Heights is so valuable—especially for families and professionals in communities like Lombard, Wheaton, and Addison:

• Early glaucoma detection: Visual field loss is often the first sign of glaucoma—before eye pressure readings rise or other symptoms develop. With our iCare tonometer and digital perimetry, we maximize your chances of catching issues at the very beginning.
• Neurological and systemic insights: Vision field analysis can reveal patterns suggestive of stroke, brain tumors, optic nerve disease, or even effects of diabetes and some medications. This is why it’s so essential for at-risk patients.
• Personalized monitoring: If you’re already treating glaucoma or another chronic eye disease, repeat testing documents even minute changes over time. This allows us to fine-tune your treatment plan and protect your sight long-term.
• Convenient access & trusted professionals: We’re near Army Trail and Bloomingdale Roads, just past Jewel-Osco—minutes from Carol Stream, Glen Ellyn, and other communities where busy lifestyles demand both expertise and ease of access.
• Insurance and transparent pricing: We accept VSP, Eyemed, Cigna, Humana, Superior Vision, Davis Vision, NVA, Spectera, UnitedHealthcare Vision, and more. Our value packages make care accessible, even if you’re uninsured.
• Comprehensive care with advanced diagnostics: Each visit can include high-resolution retinal imaging (Optomap) for widefield photos, and gentle eye pressure checks, offering a complete picture of eye health all under one roof.
