What Is Low
Vision?
Partial vision loss
that cannot be corrected causes a vision impairment known as "low
vision." A person with low vision has severely reduced visual acuity or
contrast sensitivity, a significantly obstructed field of vision -- or all
three.
Signs of Low
Vision
-
Difficulty
recognizing a familiar face
-
Difficulty reading
-- print appears broken, distorted or incomplete
-
Difficulty seeing
objects and potential hazards such as steps, curbs, walls, uneven surfaces
and furniture
Low Vision =
Useful Vision
People with low vision
usually retain some usable vision. An ophthalmologist or optometrist
specializing in low vision can evaluate how you see and prescribe optical
devices to maximize your remaining vision. This functional vision assessment is
an important step in helping improve your quality of life.
Improving Your
Functional Vision with the Help of Devices
Even with regular
eyeglasses or contact lenses, a visual image -- whether a sentence from a book
or a crosswalk at a busy intersection -- may appear distorted, blurred or
incomplete if you have low vision. A low vision doctor may recommend or
prescribe devices such as magnifiers and tinted lenses to help you take full
advantage of the sight you have. Non-optical devices such as large-print clocks
and remote controls, as well as signature and writing guides, are also popular.

Rehabilitation: The Key to Safety and
Independence
If your vision loss
can't be corrected by medical or surgical interventions, vision rehabilitation
can help. Vision rehabilitation services equip you with skills and strategies to
help you remain safe, independent and active at any stage of life.
These services are
provided by a multidisciplinary team of professionals who can introduce you to
new methods of using remaining vision to help you maximize daily functioning and
adjust to vision loss. This team includes specially trained ophthalmologists,
optometrists, social workers, nurses, occupational therapists, vision
rehabilitation therapists, career counselors, orientation and mobility
specialists and others.
