 Researchers Design New Eyeglasses to Help Patients with Hemianopia

Researchers from the Schepens Eye Research Institute of Massachusetts Eye and Ear and Harvard Medical School have created three new eyeglasses to help expand the visual fields of patients with hemianopia.

The new eyeglasses use high-power prisms embedded in the lens. One eyeglass uses yoked prisms in the carrier lens, allowing for up to 36 degrees of expansion to the visual field on the patient's blind side. Another uses a bi-part double Fresnel prism that allows for up to 43 degrees of expansion to the visual field on the patient's blind side. And the third is a mirror-based periscopic prism that may allow for up to 40 degrees of expansion to the visual field on the patient's blind side.

The research was recently published in Optometry and Vision Science.
