Prism Glasses
Specialized lenses for low vision and neurological visual disorders
Prism glasses are an important tool in vision rehabilitation and can help improve vision and visual function in patients with low vision and neurological visual disorders.
Prism glasses offer a simple, non-invasive treatment option that can improve head posture, comfort, and visual function for many patients.
Clinical Applications
How prism glasses can support visual function
Prism glasses for low vision
For some patients with low vision, prisms can redirect incoming light toward the Preferred Retinal Locus (PRL), the healthiest area of the retina that the brain naturally adopts when the central retina is damaged. By directing images to this more functional retinal area, prism glasses may improve visual clarity and, in selected patients, can result in an improvement of one or more lines of visual acuity.
Prism glasses for hemianopia
Prisms can also benefit patients with homonymous hemianopia, a condition in which half of the visual field is lost in both eyes, most commonly following a stroke or brain injury. Specially prescribed prism glasses shift images from the blind side toward the seeing side, increasing awareness of objects that would otherwise remain outside the patient's field of view.
Prism glasses for nystagmus
Dr. Monica Daibert-Nido has demonstrated that low-power prism glasses can improve abnormal head posture in patients with congenital or acquired nystagmus. In a clinical study involving more than 30 patients, low-power prisms significantly reduced compensatory head turns while maintaining excellent cosmetic appearance.
AHP pre-and-post prisms fitting
A patient who improved her abnormal head position when using the prism glasses, maintaining it after 2 years of use.
Without prisms
Before wearing the prism glasses, the patient had a 20° right face turn and a 5° right head tilt.
Using prism glasses
Plano/Plano lenses with 5 prisms Base Out / Base In - 2-year follow-up showing a 5° right head tilt.
