Low Vision Services

Maximizing remaining vision with tools and training

Overview

Low vision services, or vision rehabilitation, aim to help people whose vision loss cannot be fully corrected by glasses, contact lenses, medication, or surgery make the best use of their remaining sight. Assessment examines functional vision, including acuity, visual field, contrast sensitivity, and the daily tasks a person finds difficult. Optical devices include handheld and stand magnifiers, high powered reading spectacles, and telescopic systems for distance viewing, while electronic aids include video magnifiers and screen magnification and reading software. Non optical strategies include improved lighting, increased contrast, large print, and tactile markings. People with central vision loss, as in macular degeneration, may learn eccentric viewing, using a healthier area of peripheral retina. Orientation and mobility specialists teach safe travel using long canes, guide dogs, and other techniques, and occupational therapists address daily living skills. Because vision loss is associated with depression, isolation, and falls, rehabilitation often includes psychological and social support, delivered by multidisciplinary teams.
