Neurolens

Neurolens is a specialty ophthalmic lens featuring a contour prism design. Contour prism allows the neuro-optometrist to prescribe varying amounts of prism from distance to near in the same ophthalmic lens.

Clinical studies in the normative population have shown a reduction in headaches, vision motion sensitivity, eye fatigue, double vision, and neck pain.   Patients with binocular vision disorders (convergence insufficiency, high exophoria near, and others) have reported significant improvements in symptoms such as eye fatigue, headaches, neck pain, and double vision. These lenses may benefit patients with a wide range of binocular vision dysfunctions as well as patients with acquired/traumatic brain injury.

FAQs on Neurolens

What is Contour Prism?

Contour Prism is variable horizontal prism that increases base-in prism when looking lower in the ophthalmic lens. This is like a progressive lens design where an invisible bifocal slowly increases in reading power as the patient looks to the bottom of the lenses.

How do we test in the office?

Your neuro-optometrist will complete a binocular vision assessment, and the Neurolens virtual headset testing provide objective data points that your neuro-optometrist evaluates to provide a final prescription.

What are the indications for contour prism?

Patients may note improvement with the following conditions: convergence insufficiency, high exophoria at near, divergence insufficiency, high esophoria at distance, and other binocular vision disorders.

You may use your HSA/FSA card to purchase Neurolens lenses. Medical insurance does not cover these lenses – please check with your insurer.

Does workers’ compensation and/or auto insurance cover these lenses?

Your neuro-optometrist orders medically necessary glasses and it is evaluated by the claims adjuster. With appropriate paperwork and providing a clinical reason, there is a possibility the insurer may cover Neurolens lenses.

Do vision discount plans (EyeMed, VSP, Avesis, Davis, etc.) cover these lenses?
No, these are specialty lenses that typically do not have coverage for these lenses.

FAQs on Traditional Prism: 

What is traditional prism?

Prism is a treatment and compensatory tool to bend light to hit the appropriate area in the back of the eye, allowing the patient to eliminate double vision.

When is a prism indicated or prescribed?  

Prism is indicated for patients who have an eye turn, binocular vision dysfunction, who have symptoms of headaches, double vision, ghosting of images in visual space, eye fatigue, and many other signs/symptoms.

Comparison of Traditional Prism vs. Contour Prism

A traditional prism provides eye misalignment correction at a specific value for the entire lens while contour prism provides eye misalignment correction that varies from distance to near in the same pair of glasses. In some cases, it may allow for patients to have a single pair of glasses compared to multiple pairs.

Example 1 – Professional Driver: A patient with a traumatic brain injury notes double vision at distance and at near. The patient notes that the double vision is worse at near than at a distance. A neuro-optometrist diagnoses convergence insufficiency.
