This single-subject study explored the effects of different mounting systems of prescribed near magnification (handheld, stand-mounted, spectacle-mounted, and electronic) on reading performance and preference in students with low vision. Participants included five students ranging from 3rd to 11th grade, and with various etiologies. Reading performance and preference varied widely with each mounting system, with no clear patterns across students. The differences in mounting systems did appear to be a determining factor in the reading performance and preference among students and should be taken into account when selecting and prescribing devices for students.
