The Technology
Prism correction.
In your glasses.
Standard eyeglass lenses correct for clarity — nearsightedness, farsightedness, astigmatism. They do not address the alignment of the two eyes relative to each other.
Binocular Vision Dysfunction (BVD) is a subtle misalignment between the eyes that forces the brain to work constantly to maintain single, fused vision. The result is headaches, dizziness, eye strain, and a cascade of symptoms that seem unrelated to vision.
TheraLens incorporates micro-prism correction directly into an eyeglass lens, bending incoming light so both eyes receive images that are already aligned. This eliminates the neurological strain of constant correction — and the symptoms it generates.
TheraLens is prescribed and fitted by Dr. Payne following a comprehensive NeuroVisual evaluation. The fitting process is more detailed than a standard eye exam, ensuring the prism correction is precisely calibrated to your visual system.

How It Works
The science behind
TheraLens.
Prism Correction in an Eyeglass Lens
TheraLens incorporates micro-prism correction directly into an eyeglass lens, correcting the misalignment between the two eyes at the optical level. The prism bends incoming light so that both eyes receive images that are already aligned, eliminating the neurological strain of constant correction.
Addresses the Root Cause of BVD
Like all NeuroVisual treatments, TheraLens targets Binocular Vision Dysfunction — the subtle misalignment of the eyes that forces the brain to work constantly to maintain single, fused vision. By correcting the alignment at the lens level, TheraLens reduces the neurological strain that causes headaches, dizziness, and visual fatigue.
Precision Fitting by Dr. Payne
TheraLens fitting requires a specialized NeuroVisual evaluation to determine the precise prism correction needed. Dr. Payne measures the degree and direction of misalignment using advanced diagnostic techniques, then prescribes a TheraLens configured to your specific visual system.
Compatible with Your Full Prescription
TheraLens incorporates your complete refractive prescription — correction for nearsightedness, farsightedness, and astigmatism — alongside the prism correction. Your TheraLens glasses serve as your complete vision correction, with no need for a separate pair.
Who Benefits
TheraLens is designed
for you if…
Glasses Wearers with BVD
Patients who already wear glasses and have been diagnosed with BVD are natural TheraLens candidates. The prism correction is incorporated directly into their existing lens format, making the transition straightforward.
Patients with Unexplained Headaches
Many BVD patients have seen multiple specialists without a clear diagnosis. If your headaches are reliably worse during or after visual tasks — reading, screens, driving — and improve with rest or eye closure, BVD and TheraLens may be the answer.
Screen-Heavy Professionals
Patients who spend long hours at computers, reading, or doing close visual work often experience the most dramatic relief from TheraLens. The prism correction reduces the sustained neurological effort that makes extended screen time so fatiguing.
Post-Concussion Patients
Post-concussion patients frequently develop or worsen BVD after a head injury. TheraLens addresses the visual component of post-concussion syndrome — headaches, dizziness, and cognitive fatigue that persist long after the initial injury.

Frequently Asked Questions
Everything you need
to know.
What is TheraLens?
TheraLens is a specialty eyeglass lens that incorporates micro-prism correction for Binocular Vision Dysfunction (BVD). It is worn in a glasses frame and corrects the subtle misalignment between the two eyes that causes headaches, dizziness, and visual fatigue. TheraLens is prescribed and fitted by Dr. Payne following a comprehensive NeuroVisual evaluation.
How is TheraLens different from NeuroLens?
Both TheraLens and NeuroLens are eyeglass lenses that treat BVD with prism correction. NeuroLens uses a contoured prism design — the prism power varies across the lens surface to match how the eyes naturally move and converge at different distances, making it particularly effective for digital eye strain. TheraLens uses a different prism delivery approach. Dr. Payne will determine which lens design is most appropriate for your specific presentation and symptom profile.
Can TheraLens incorporate my existing glasses prescription?
Yes. TheraLens incorporates your full refractive prescription alongside the prism correction. If you currently wear glasses for nearsightedness, farsightedness, or astigmatism, Dr. Payne will incorporate that correction into your TheraLens prescription. Your TheraLens glasses will serve as your complete vision correction.
How is the TheraLens prescription determined?
TheraLens fitting begins with a comprehensive NeuroVisual evaluation — a specialized examination that measures the degree and direction of eye misalignment at multiple distances and gaze positions. This evaluation is more detailed than a standard eye exam and takes approximately 60 to 90 minutes. The findings determine the precise prism correction incorporated into your TheraLens.
Is TheraLens covered by insurance?
TheraLens is a specialty lens and coverage varies by plan. The underlying eye exam may be partially covered by vision or medical insurance. Our team will review your benefits before your appointment and discuss financing options including Cherry and CareCredit if needed.
Can TheraLens be combined with Avulux lenses?
Yes. Patients who experience both BVD symptoms and light sensitivity or migraines can have TheraLens prism correction incorporated into Avulux-tinted frames, or wear Avulux glasses as a second pair for high-light environments. Dr. Payne will recommend the best approach for your specific combination of symptoms.
What is the adjustment period for TheraLens?
Most patients adapt to TheraLens within one to two weeks. Some notice immediate improvement in symptoms; others experience a gradual reduction in headaches, dizziness, and visual fatigue over the first few weeks. Dr. Payne schedules follow-up appointments to monitor your response and fine-tune the prescription as needed. As with all prism prescriptions, small adjustments may be required during the first several months.
What results can I expect from TheraLens?
Most TheraLens patients notice meaningful improvement in headaches, dizziness, and visual fatigue within the first one to two weeks of consistent wear. Because TheraLens addresses the root cause of BVD symptoms — the misalignment itself — the relief is sustained as long as the lenses are worn. The goal is not just symptom reduction, but restoring the visual system to a state where it can function comfortably throughout the day without generating pain or fatigue.
Is TheraLens available for patients with astigmatism?
Yes. TheraLens can be configured for patients with astigmatism. Dr. Payne will assess your full refractive status during the NeuroVisual evaluation and incorporate any astigmatism correction into your TheraLens prescription alongside the prism correction.
How do I know if I am a candidate for TheraLens?
The best first step is taking the free BVD symptom questionnaire on our website. If your symptoms are consistent with Binocular Vision Dysfunction — headaches, dizziness, reading difficulties, neck pain, or visual fatigue — you are likely a good candidate. A NeuroVisual evaluation with Dr. Payne will confirm the diagnosis and determine whether TheraLens, NeuroLens, or a combination approach is the right treatment for your specific presentation.
