Telesensory (http://www.telesensory.com/), the leading worldwide developer, manufacturer and marketer of products to assist people with low vision announced that it has entered into an agreement with Microvision (Nasdaq: MVIS, http://www.mvis.com/), developer of the patented retinal scanning display (RSD) technology, for the purchase of Microvision Nomad wearable displays. Telesensory plans to combine its line of low-vision products with the Nomad display to improve the ability of people with low vision to read printed material.

Nomad integrates Microvision’s patented retinal scanning display (RSD) technology into head worn devices, and allows an individual to view images without the need for a cumbersome screen. The technology scans a low-power beam of light to "paint" rows of pixels to the eye, creating a high resolution, see-through, full-motion image without the use of electronic screens of any kind. To the viewer, the image appears to be floating directly in front of them at about an arm’s length away, as if on a large computer or television monitor.

The special characteristics of Nomad make it ideal for the partially sighted. These include: fully directed scanned light to create the brightest images of any display technology, high contrast range, and no need for a large physical screen, creating a wearable low vision aid that allows the user access to virtually any printed material.

Telesensory will focus initially on using the Nomad devices to help people afflicted with age related macular degeneration (AMD). AMD is the leading cause of new blindness in the USA with estimates ranging as high as 200,000 new cases diagnosed each year.

Telesensory will initially begin clinical evaluations for a 90-day period using Microvision’s current prototype system, and is in the process of selecting several private and public low vision clinics to participate.

About visual impairment

The number of individuals worldwide suffering from visual impairment is large. The condition of visual impairment is defined as the existence of vision deficiencies that are not correctable through the use of glasses or contacts. In the United States an estimated 15 million people suffer from visual impairment, with an estimated 2 million new cases per year.

The incidence of visual impairment increases with age. The prevalence of this condition is expected to grow as the population over age 65 expands over the next several decades. One in eight Americans between the ages of 55 and 64 will be afflicted with visual impairment. The prevalence of impairment rises to one in six Americans between the ages of 64 and 74, and one in three over the age of 75.

Telesensory is the leading worldwide developer, manufacturer, and marketer of electronic and computer-based products to assist people with low vision. For over three decades, Telesensory has been helping visually impaired and blind people achieve greater independence through innovative, technology-based products.
