Prescribing Magnification: Strategies for improving Accuracy and Consistency
All low vision practitioners develop their own individual approaches to prescribing magnifying devices. The simplest is the “cafeteria” approach in which the patient is presented with an array of low vision magnifiers and asked to make a selection. In time, the cafeteria will develop a corner delicatessan atmosphere with the proprietor proudly giving advice based on the experience and comments of previous customers. “Try this one, it seems stronger.” “Try moving closer, that often helps.” “See if it looks better through the bifocal part of your glasses.” In contrast, trained professionals prefer to use systems based on measurements of resolution ability, magnification effects, tests of performance and judgements of comfort and convenience.
