These new ergonomically designed stand magnifiers offer a more comfortable viewing angle, the capacity for both reading and writing, a wider field of view, more illumination, and also variable power. These four new magnifiers are a spherical mirror magnifier, a cylindrical mirror magnifier, a reflecting prism magnifier, and a variable power zoom magnifier. These units have been developed and clinically tested on low vision patients at five clinical testing sites. Results show that 29 out of 39 patients picked one of the new magnifiers as their device of choice over a comparable commercial stand magnifier.
