Fresnel prism

18 devices · GMDN 32718

Fresnel prisms are thin plastic sheets with embossed rulings that provide the optical effect of a prism when applied to spectacle lenses. They are primarily used to manage strabismus and other eye muscle dysfunction by redirecting light entering the eye.

These devices are typically applied to spectacle lenses either temporarily to assess a patient's response to prismatic power or as a permanent solution. Fresnel prisms are supplied as adhesive sheets that can be attached to existing eyeglass lenses to achieve the desired optical effect.
