Low Vision is an area of Optometry which helps patients with visual impairments that are not fully treatable by medical, surgical or conventional eyeglasses or contact lenses. A patient with low vision is someone who can no longer do normal daily tasks as a result of a vision problem. A different approach is required for each patient based on their individual visual needs, central and peripheral vision remaining and general health.
A wide variety of rehabilitation options are available to help people with low vision live more successfully and safely. There are many different low vision treatment options and some of the more commonly prescribed devices include:
- Spectacle-mounted magnifiers or microscopes
- Hand-held or spectacle-mounted telescopes

- Closed-circuit televisions
In addition, there are numerous other products to assist those with vision impairment, such as large-print books, talking books, talking wristwatches, self-threading needles, and more.
Few people are totally without sight. Ninety percent of individuals classified as "legally blind" actually have some vision.
