Binocular lenses12/18/2023 ![]() Numerous seemingly unrelated physical symptoms may be related to eye alignment strain. Second, a visual aid-in this case, the Neurolens glasses-must be customized to minimize or eliminate that person’s specific problem. That’s the purpose of the Neurolens measurement device. To help patients deal with this, two things are necessary: First, a device must be able to measure the extent of the problem in a given individual. 42 percent have discomfort at the computer įifty-six percent of patients present with at least three of these symptoms.50 percent experience neck pain or stiffness.53 percent of eye-care patients complain of “tired eyes”.The company claims that this is reflected in complaints reported during more than 17,000 eye exams. When the visual system has to strain to compensate for misalignment and/or disagreement between central and peripheral images, double vision may result but even if double vision doesn’t occur, the trigeminal nerve can still become overstimulated, leading to trigeminal dysphoria and triggering symptoms. The proprioceptive signals involved in that feedback loop are transmitted through the ophthalmic branch of the trigeminal nerve. ![]() How does stressing of the eyes and brain lead to these symptoms? According to EyeBrain, in addition to combining images in the face of ocular motor imbalances-a challenge in itself-the brain maintains a feedback loop with the extraocular muscles to keep the eyes aligned. adults complain of headaches, neck/shoulder pain and eyestrain when using these devices. So it shouldn’t be surprising that a huge percent of U.S. According to the company, the average American adult spends more than nine hours a day using digital devices-with 70 percent of Americans using two or more devices at the same time. Any of these can be misdiagnosed.ĮyeBrain Medical, a company located in Costa Mesa, California, has created the Neurolens measurement device and contoured prism glasses to help solve this problem. It was probably inevitable that this would lead to vision problems, because when the eye muscles and brain have to maintain a near focus for a long time, we can experience everything from headaches to dry eyes to shoulder and neck pain. The digital revolution we’re living through has spawned a host of new devices that invite us to stare at screens. Here, doctors profile two new systems that can help to diagnose and manage problems tied to maintaining binocular vision. Other times, even when we’re successfully experiencing binocular vision, we pay a price for doing so because maintaining it requires an extraordinary amount of effort. Sometimes the muscles controlling the eyes have difficulty accomplishing that, leading to double vision. But good binocular vision requires more than just two eyes that see well the input to both eyes must be successfully combined by our eyes and brain to create our experience of a three-dimensional environment. O phthalmologists spend much of their time helping patients maintain (or regain) excellent visual acuity.
