prismögon

Prismögon, also known as prism glasses, are a type of corrective eyewear that incorporates prisms into the lenses. These prisms are not for correcting refractive errors like myopia or hyperopia, but rather for redirecting light to help with certain visual conditions. The primary purpose of prismögon is to shift the image that falls on the retina, thereby altering the perceived direction of objects. This can be beneficial for individuals experiencing double vision (diplopia) or misalignment of the eyes (strabismus).

The way prisms work is by bending light. The base of the prism dictates the direction in which the light is bent. By strategically placing the prism in the eyeglass lens, an ophthalmologist or optometrist can realign the images seen by each eye, making them fuse into a single image. This can significantly reduce visual discomfort and improve visual function for those affected by binocular vision disorders.

The prescription for prismögon is determined through a comprehensive eye examination that assesses binocular vision. The strength of the prism is measured in prism diopters, and the orientation of the base is also specified. Prismögon can be incorporated into single vision lenses, bifocals, or progressive lenses, depending on the patient's refractive needs. While they can be very effective, prismögon are typically prescribed for specific conditions and may not be suitable for everyone. They are not a cure for underlying eye conditions but rather a management tool to alleviate symptoms.
