A multipurpose low-vision aid.

We constructed a low-vision aid for a 61-year-old patient who had familial macular degeneration and a visual acuity of 20/300. The aid consisted of a spectacle lens incorporating his distance prescription as the carrier, a high-plus bifocal reading addition, and the high-minus ocular lens of a Galilean telescope of variable magnification. The objective lens of the telescope can be carried as a folding, dual-lens, hand magnifier.
