Low
Vision
Over
three million people in the United States do not have normal
vision even with corrective lenses. If ordinary eyeglasses
do not provide clear vision, one is said to have low vision.
This should not be confused with blindness. People with
low vision still have useful vision that can often be improved
with low-vision devices.
Low
vision can result from birth defects, inherited diseases,
injuries, diabetes, glaucoma or macular degeneration. Although
reduced central or reading vision is most common, a person
can have low vision in their side (peripheral) vision, or
a loss of color vision or contrast sensitivity.
Low
vision devices or aides are available in optical and non-optical
types. Optical devices use lenses or combinations of lenses
to provide magnification. They should not be confused with
standard eyeglasses. There are five main kinds of optical
devices: magnifying spectacles, hand magnifiers, stand magnifiers,
telescopes and closed-circuit television. Different devices
may be needed for different purposes. If possible, try the
optical device before purchasing it and be sure you understand
how to use it.
The
simplest non-optical technique is to bring the object of
interest closer. Non-optical low vision devices include
large print books, check writing guides, enlarged phone
dials, talking appliances (timers, clocks, computers), and
machines that scan print and read out loud.

office can provide a referral to an area low-vision specialist.
