2008-Sep-9 - Wearing Eye glasses for low vision? |
Eye glasses
for macular degeneration are one of the most common and effective
solutions for people with macular degeneration and associated vision
problems. Central vision, which is vital for ordinary everyday
activities such as reading, working at the computer and driving, is
what is primarily affected by macular degeneration. Although there is
no cure for macular degeneration, those suffering from the vision
problems caused by this condition can maximize the vision that they
still have with low vision devices such as special magnifiers and other
high-tech low vision aids; telescopic glasses and eye glasses for
macular degeneration is only one of the many options available.
To
clarify how these low-vision aids work, it??s helpful to understand what
age-related macular degeneration is and how it causes vision problems.
The macula is located in the central part of the retina. Over time,
macular cells start to die off or deteriorate, or else there is
excessive blood vessel growth which causes bleeding underneath the
macula. The result is damage to this part of the eye, which is what
allows us to see fine details close up. Although peripheral vision is
usually unaffected, activities that require attention to detail ?C such
as crafts, driving and reading ?C become nearly impossible without the
use of low vision devices.
Telescopic glasses are one
solution for those suffering vision problems because of age-related
macular degeneration. These special magnifiers consist of minature
binoculars that are mounted either in front or above eye glasses for
macular degeration. As far as low vision aids go, telescopic glasses
are fairly low-tech, but are often the most effective solution for
those with vision problems due to macular degeneration. These
particular eye glasses for macular degeneration are also known as
?°bioptic glasses.?±
Of course, there are several other low
vision devices in addition to eye glasses for macular degeneration.
Some of these are low vision aids that were the stuff of science
fiction only forty years ago; others make new uses of old technology
such as the television camera.
Considering that television
is blamed for the decline in literacy in America, it is ironic that one
of the most effective magnifiers for those with macular-degeneration
vision problems who want to be able to read again consists of a
closed-circuit TV camera and a monitor screen. The camera projects the
image of the printed page up on the screen, enabling the patient to see
it more clearly.
If the patient??s condition is beyond what
eye glasses for macular degeneration can do, there is now software that
actually allows the user to speak to his/her computer by using a
microphone; the computer actually transforms this speech into actual
text. There are also Braille printers available for PCs and Macintosh
computers. However, if the condition is caught early enough, eye
glasses for macular degeneration may be the best solution for most
patients.
