ABSTRACT:
Eye glasses are disclosed for improving the vision of people with macular degeneration, optic nerve damage or similar low vision problems. The glasses comprise two lens assemblies, each having a magnifying lens with two convex surfaces and a reducing lens with two concave surfaces. The reducing lens incorporates prism rings which focus an image or light onto an undamaged portion of the macular. A frame is employed for supporting each assembly at a predetermined distance from an eye of a user and for supporting the lenses assembly in a predetermined orientation with respect to each other with the lenses defining a fixed space therebetween. Also disclosed are the lenses themselves and the method of using them.
