title: Advanced low vision optics.
abstract: 1. The concepts of magnification rating, equivalent power, image location, enlargement ratio, and combined reading power confront the practitioner who uses magnification when working with low-vision patients. 2. The discussion of these advanced concepts gives the low-vision practitioner new insight into accurately recommending magnifiers. 3. These concepts should be integrated into the everyday work of professionals who optically rehabilitate patients with visual impairment.
