Concept & Technology


Low Vision Readers give those with mild to moderate vision impairments the best possible chance of reading. This new technology overcomes the main factors which prevent individuals with low vision from reading – poor contrast and lighting and unrecognizable letters – by providing concentrated lighting, magnification, and prism correction. The combination of these elements permits some with low vision or vision impairment to read.

Who will benefit from Low Vision Readers? Persons with “low vision” are those who can not read with ordinary reading glasses or contact lenses and whose condition can not be corrected with surgery.  Persons afflicted with macular degeneration, diabetic retinopathy, glaucoma, inherited macular diseases, and other vision impairing or blinding eye diseases often have low vision.

Low Vision Readers were developed by Dr. Jeffrey Sonsino, founder of the Center for Sight Enhancement at the Vanderbilt Eye Institute, after careful study of hundreds of patients with low vision.  Low vision rehabilitation is an approach which makes the best possible use of the healthy vision remaining in the eye.

A number of devices exist which attempt to help individuals cope with visual impairments. Some are large, bulky, expensive, and must be prescribed by a low vision specialist. Others simply do not accomplish the intended goal. For example, there are currently available high powered reading glasses with prism but which contain NO illumination. Similarly, there are cheap glasses with inferior light and NO prism. These glasses fail for the majority of patients with low vision.

Low Vision Readers are portable, far less bulky, easier to use than other reading aids, and less expensive than a good set of progressive glasses.
