Wearable Low Vision Aids Using Retinal Light Scanning Technologies
Introduction Severe visual impairment (those persons classified as legally blind) affects over 1 million Americans currently. With the aging of the U.S. population, this visually impaired segment is expected to rise at 10 times the rate of general population growth. Technology description Researchers at the UW have developed a wearable low vision aid (WLVA). This new technology does not require bulky pixel arrays so there is high potential for miniaturization to a form factor compatible with the frame of eyeglasses. The WLVA uses a fiberoptic scanner to project images directly on the retina using a safe, low-power laser beam. Business opportunity In addition to the visually impaired, a partially sighted person would also benefit greatly from a WLVA. This broader definition of low vision (worse than 20/40 visual acuity) includes over 14 million Americans, or 25% of Americans over 75. Stage of development Initial data exist for this technology. Intellectual property position This technology is available for licensing. The UW is currently reviewing this technology for worldwide patent protection.
