Phase I

Contract Number: 1R43EY008156-01A1
Start Date: 00/00/00    Completed: 00/00/00
Phase I year
1989
Phase I Amount
$50,000
Stand magnifiers are frequently dispensed to low-vision patients and the aged for reading and other near work. More magnifiers could be dispensed and used with better efficiency if they were designed with ergonomic features. These new magnifiers, developed specifically for the partially sighted, offer a wider field of view, a comfortable viewing angle, and the capacity for reading and writing with the same magnifier. These features and others permit higher reading speeds, longer reading durations, more comfortable use, less fatigue, and greater acceptance and utilization.A prototype has been developed of each of three magnifiers: (1) a spherical mirror magnifier that reads one-column wide, (2) a magnifier with a cylindrical mirror that reads one-page wide, and (3) a reflecting prism magnifier. In Phase I, it is planned to make more prototypes of these three magnifiers, perform a study to evaluate their advantages at three independent testing sites, and develop folding and Fresnel versions of each magnifier to make them more compact. In Phase II, the results of the Phase I study will be used to redesign the prototypes with respect to optical and physical parameters, and then to develop inexpensive production prototypes to be sold to the partially sighted for reading and writing.

Anticipated Results:
These new magnifiers have great commercial potential because they have advantages for reading and writing over present stand magnifiers. They may even be compared to CCTV's for reading speed and duration, but they are much less expensive (below $35) and more portable. The Houston Lighthouse is manufacturing and marketing the spherical mirror magnifier.National Eye Institute (NEI)

Stand magnifiers are frequently dispensed to low vision patients and the aged for reading and other near work. More magnifiers could be dispensed and used with better efficiency with the ergonomic advantages of these new magnifiers. These new magnifiers, developed specifically for the partially sighted, offer a wider field of view, a comfortable viewing angle, and the capacity for reading and writing with the same magnifier. These features and others permit higher reading speeds, longer reading durations, more comfortable use, less fatigue, and greater acceptance and utilization. A prototype has been developed of each of four magnifiers; 1) a spherical mirror magnifier which reads one column wide; 2) a magnifier with a cylindrical mirror which reads one page wide; 3) a reflecting prism magnifier; and 4) a zoom magnif ier. In Phase I, we will make more prototypes of these four magnifiers, perform a study to evaluate their advantages at three independent testing sites, and develop folding versions of each magnifier to make them more compact. In Phase II, the results of the Phase I study will be used to re-design the prototypes with respect to optical and physical parameters, and then develop inexpensive production prototypes to be sold to the partially sighted for reading and writing.Awardee's statement of the potential commercial applications of the research:These new magnifiers have great conunercial potential since they have advantages for reading and writing over present stand magnifiers. The price to the public can be below $35.National Eye Institute (NEI)
