RE:Stand Magnifier Optical Strategies
Attached are "Worksheets for choosing a lighted stand magnifier/spectacle add combination." All magnification measurements were made using methods discussed in the Visibility article, "Stand Magnifier Optical Strategies," Volume 12, Issue 1: https://university.envisionus.com/Visibility/Volume-12-Issue-1-Baldwin

RE:Stand Magnifier Optical Strategies
Stand magnifiers produce focused magnification that is dependent on the spectacle add used with them. Each stand magnifier has a maximum spectacle add that will produce a clear image. Please see the attachment for a course on Stand Magnifier Strategies.

RE:Stand Magnifier Optical Strategies
Internal magnifier lighting increases contrast and decreases the effects of glare from external lighting sources. This is normally important for those patients who are not abnormally sensitive to glare from direct light sources. However, there are patients for whom this is not necessary, and who would benefit from maintaining binocular vision while using a stand magnifier. (See attached presentation)

RE:Stand Magnifier Optical Strategies
Using various trial lighted hand magnifiers with the needed distance correction, either via glasses or contacts, the required magnification for a specific task can be found, and a lighted stand magnifier and reading add combination can be predicted that provides the required magnification with the preferred working distance.
