Low vision is a reduced level of vision that cannot be fully corrected with conventional glasses. Low vision typically interferes with the performance of daily activities; however, unlike with blindness, a person with low vision has some useful sight.
A wide variety of rehabilitation options are available to help people with low vision live and/or work more effectively, efficiently, and safely. Some commonly prescribed devices are:
- Spectacle-mounted magnifiers
- Hand-held or spectacle-mounted telescopes
- Hand-held and stand magnifiers
- Video magnification (closed-circuit television)
- Special tints and lens treatments
In addition, there are numerous other products to assist those with a vision impairment, such as large-type books, magazines, and newspapers, books-on-tape, talking wristwatches, self-threading needles, and more.
