What Is Prism Therapy?

Prism therapy is a type of vision therapy that helps binocular visual problems. Binocular vision is when the brain is not able to have both eyes working together at the same time. This can cause you to have double vision, your eyes can turn inward or outward, and you may have trouble focusing. Prism therapy is when your optometrist adds corrective prisms to the current lenses in your glasses. It does not change the way your lenses look. Your brain, however, can process the change the prism creates to images you see through your lenses. If you think you may have problems with binocular vision and you are in the New Hyde Park area, visit Village Optical today.

How Can Prism Therapy Help Me?

Often you wear glasses to correct vision problems, but it may not fix all of your vision problems. You may find yourself suffering from eye strain or the inability of your eyes to focus. If you use a computer screen for work, that may make your symptoms worse. You may also find yourself struggling when you have to look at the small text for long periods of time. Your optometry staff may determine that you need prism correction in your eyeglasses. It can be prescribed for just one eye or both eyes, depending on your vision needs.

How Do Prism Lenses Work?

A prism can help to turn your eyes in the same direction. They can also help the brain correct itself so it learns to tell the eyes the correct way to move. Regular lenses bend and focus the light coming into the lenses. Prism lenses refract light in a different way so they have a different impact on your vision. When prisms are used in eyeglasses, they change the direction of what you see. This helps to change your double vision into a single vision and make some vision corrections.

Prism Therapy FAQs

Not many people have heard about Prism therapy. It is a procedure used to treat patients with vision problems that stem from an injury or condition that affects the oculomotor system. In these patients, the eye does not track objects in the real world in the way that it should. You might think of it as being similar to a rifle that has a maladjusted scope. When the user attempts to fire at a given point, the projectile is off the mark. Prism therapy aims to correct the neurological diversion of the patient’s eye and her or his intended point of focus.

What Is Prism Therapy?

Prism therapy, or prism adaptation therapy, is used to treat losses in visuospatial ability in patients with certain neurological disorders.

How Does Prism Therapy Work?

Prism adaptation therapy helps patients achieve better oculomotor control by helping them to compensate for measured losses in oculomotor control. A prism is a device that diverts light without focusing or diffusing it, splitting white light into its component colors. By exposing the patient to calculated diversions of light and image, the visual system can be stimulated into compensating for the change.

How Are Prisms Used In PT?

The two primary ways prism therapy is used are compensatory and therapeutic prism vision therapy. The purpose of compensatory PT is to reduce the workload of the patient by compensating for visual acuity defects. Therapeutic PT increases the workload on the patient’s visual system in order to strengthen it.

How Does The Visual System Respond To PT?

There are four primary ways in which the visual system can and may respond to prism therapy. It could not respond at all, in which case the resulting image is blurry or doubled. This can be remedied by making changes in the way the prism is deployed. The second way the visual system may respond is with a blurry and a non-double image. It could also respond with a clear and a double image or a clear and single image.

What Vision Training Techniques Are Used?

The four techniques your eye doctor may use are:

1. To stimulate eye movement toward the apex of the prism

2. To stimulate convergence on a given point

3. To stimulate divergence from a given point

4. To decrease suppression

These probably all sound rather cryptic, but these are just the different ways your optometrist can use prism therapy to adjust damaged vision.
