People who suffer from binocular vision disorders have a variety of symptoms, ranging from dizziness and nausea to blurred vision. These individuals may not have to rely on prescription drugs to receive relief. Instead, here at the Neuro Visual Center of New York, we use special aligning prismatic lenses to help our patients find relief from their symptoms.
What is Vertical Heterophoria?
Unlike regular eyeglasses and contacts that correct refractive errors caused by irregularities in the shape of your eyes, prismatic lenses treat misalignments of the eyes caused by a binocular vision dysfunction known as vertical heterophoria (VH). When the eyes are misaligned, you see slightly different images in each eye because they’re not on the same level. Your brain will automatically correct this problem, but the correction results in tired, overworked intraocular muscles, which can lead to balance issues and double vision symptoms. Fortunately, these issues can be treated with specialty aligning prismatic lenses.
Treating VH with Prismatic Lenses
A prism works by moving images. If you hold a prism in front of one eye, the light passing through it will change direction, thus moving the image. By manipulating the placement and amount of prism within prismatic lenses, the symptoms of VH can be greatly reduced or even eliminated.
Our doctors can utilize prismatic lenses in eyeglasses or as a pair of contacts. They are able to use very precise amounts of prism to move the images the patient sees, manipulating light before it enters the eye and making the images appear to be on the same plane. This tricks the eyes into believing that they’re correctly aligned. With the intraocular muscles no longer having to strain to correct the misalignment, the symptoms of VH are greatly reduced or even disappear altogether.
While prism glasses are a visual orthotic device, you don’t have to worry about standing out or looking odd to the outside world while wearing them. They appear just the same as regular eyeglasses, except they’re like your medicine. No drugs, just glasses.
