1. What is Low Vision
Low vision means vision that is less than normal and regular glasses,
contact lenses, medicine or surgery will not improve. Daily activities
like driving, reading mail or prescription bottles, preparing meals, seeing
TV and recognizing faces may be difficult or impossible without special
magnifiers or vision enhancement equipment.
2.
Why don’t stronger glasses make my vision better? I see a lot of
people with thick glasses and they seem to see o.k.
Glasses
are only able to focus the picture for your eye. If the retina is damaged
from macular degeneration or other diseases it is like having bad film
in the camera and changing glasses won’t make objects clearer. Glasses
are like shoes - there is only one size shoe that fits you and there is
only one power of glasses that fits your eye, so just as bigger shoes
don’t allow you to walk better, stronger glasses don’t allow
you to see better in the distance. However, very strong reading glasses
may allow you to see small print that is held very close to your eyes.
3.
Can I get glasses to help me see better when I drive or help me get my
drivers license?
Glasses
can improve the vision of people whose only vision problem is that they
are nearsighted or farsighted or have astigmatism. Even the best glasses
cannot overcome vision problems caused by eye diseases like macular degeneration,
and therefore better glasses don’t allow you to see down the road
better.
4.
What is legally blind? Can I still read if I’m legally blind?
Legal
blindness means vision in your best eye, with your best glasses, 20/200
or a severe visual field loss. It is not a measure of how much you can
do or of how active you can be. With special devices and training, many
people who are legally blind can read and write.
5. Does it hurt my eyes to sit close to the TV?
No.
Physical harm cannot be done to the eyes by sitting close to a television
set. Even sitting at 1-3 feet is o.k.. Radiation or other damage does
not occur and more detail can often be seen because as you sit closer
the picture is bigger.
6.
Can I damage my eyes by using them a lot or if I’m straining to
see? They often feel uncomfortable when I work so hard to see things.
You
cannot overuse your eyes. They may feel uncomfortable or strained but
this is from fatigue and your eyes will not be damaged. You may not be
able to use them for as long a duration as you once did, but no harm will
be experienced from use. Resting and sometimes using lubricant eye drops,
as often as you feel the need, will allow you to resume visual activities
and your eyes will feel better. Generally endurance improves with persistent
practice.
7.
Do I still need to see my other eye doctor (s)?
Even
if you were referred to a vision rehabilitation specialist, you still
need to see your regular eye doctors who are providing general care or
treating specific medical/surgical eye problems. The rehabilitation specialist
helps you do the most with the vision you have, with adaptive techniques,
devices and training. Your other eye doctor (s) tries to help maintain
the vision you have with medical treatment or surgery. Both types of care
may be going on at the same time.
8.
Does my insurance/Medicare cover any part of Low Vision Rehabilitation?
Many
insurances, including Medicare, cover a comprehensive evaluation and training
in adaptive techniques by recognized Low Vision Rehabilitation professionals.
Insurances generally do not pay for optical assistive devices, however.
9.
Why does it take time to find a way to help me see better? I want it fixed
right now.
Seeing
is complicated. It includes recognizing detail, distinguishing objects
from their background (contrast sensitivity), having a full field of view,
managing glare and processing the visual message. Eye diseases may affect
each of these differently for different people. To maximize your vision,
each problem needs to be addressed for each task you want to do, and this
takes time, training, work, practice and patience.
10.
I sometimes have a sensation of seeing things that aren’t there.
Is that a dangerous sign about my eyes or is there something wrong with
me mentally?
This is a very common occurrence in people who have
lost some vision. You may see colorful geometric patterns, people, animals
or elaborate scenes anywhere you look and although they look real, you
know they are not. This experience is often called phantom vision and
the medical term is Charles Bonnet Syndrome. It is believed to be similar
to phantom sensations that some people experience after limb loss. Charles
Bonnet Syndrome is not an indication of worsening eye disease or of mental
illness. It tends to become less frequent over time and rarely requires
any treatment.
11.
Why are parts of words missing and some small objects hard to find when
I put them down? Sometimes I can see very small things, which puzzles
me and other people?
Our
central vision allows us to see what we look at directly and our peripheral
vision allows us to see out of the corner of our eyes. Some eye conditions,
including macular degeneration, cause blind spots or blurry areas in our
central vision but leave peripheral vision intact. This means that out
of the corner of your eye, your good peripheral vision may spot a small
button on the floor, but the blurry area in your central vision, makes
it disappear when you go to pick it up. If the blurry area or blind spot
is small, you may see part of a word, or if you have several small blind
spots words may pop in and out of your view.
12.
Can I get a bigger strong magnifier so I can see more at one time? I can’t
see enough with this small lens.
In general the bigger the magnifier the weaker it is, and the smaller
the magnifier the stronger it is. This is because strong magnifiers are
very thick and cannot be made very large. Training and practice allows
you to use magnifiers, even small ones, more effectively. Electronic magnifiers
with screens offer strong magnification with a larger area of view.
13.
Why can I read when I am here using your light but I can’t with
my light at home? I use a 200 watt bulb.
Higher watt bulbs alone do not necessarily make it easier to see print
or perform other tasks. The type of bulb and direction of light is important.
A low watt floodlight bulb in a gooseneck lamp, for example, is usually
better than a high watt bulb in a shade lamp because the gooseneck lamp
directs the light onto the print while the shade lamp beams its light
in all directions. Different kinds of bulbs may provide optimal light,
for example fluorescent, halogen or Chromolux. Low vision rehabilitation
offices usually have optimal lighting, which you can also place in your
home.
14.
Where can I get talking books?
The Library of Congress Talking Books program is available free of charge
to anyone who cannot read standard size print. The Talking Book tape player
and cassettes of books and magazines are distributed through State or
county libraries (see our resources list). Your eye care professional
or agencies dealing with the visually impaired can provide you with an
application and authorize use of the program.
15.
Why can’t I buy a magnifier at the store that will help me?
Most over the counter magnifiers are of low power and usually lower quality.
They are not designed to be used by people with more advanced visual impairments.
Patients with very early loss of vision may find help with this type of
device. As the vision deficit becomes more severe the type and power of
assistive device is better determined by an experienced Low Vision specialist
who can match it to your vision level and needs.
16.
Do I qualify for a benefit on my income taxes?
If you are “legally blind” (best vision of 20/200 or severe
field loss, as determined by your eye doctor) you qualify for an additional
deduction on your income tax.
Some
Low Vision Rehabilitation programs emphasize visual skills and eccentric
viewing training (use of undamaged parts of the retina that see a more
complete and clearer picture). These questions are common in the program
we offer at Low Vision Solutions.
A.
How will using an eccentric viewing position help me?
The normal visual system positions
your eye so the image you are trying to see falls on the center of the
macula. If that part of the retina is damaged you see a blur (inability
to recognize faces) or an incomplete picture (miss parts of a word or
letters within a word). This is very disruptive to reading and writing
and other daily activities. By moving the eye to a different position
when the center is damaged, you can receive a more complete and clearer
picture of what you are trying to see. This will help you perform many
of your activities more easily and increase your success with assistive
devices.
B.
Why does it require so much training time and how long will it take?
Re-educating the eye and brain to perform fine detailed
activities with a new retinal location is a complex task. It is reprogramming
your biologic computer. Activities you performed automatically now require
a new system to complete. Once learned however it will speed up performance
and activities will be accomplished with much less frustration. Patients
frequently don’t achieve a breakthrough for 3 or 4 visits. The average
number of visits to complete the program is 3 to 6.
C.
Can’t I do the training on my own at home? Aren’t there instructions
on how to do it?
Practice can be done at home and it does make a difference in progress
and success. Because this is a complex process and everyone learns differently
and has a different set of problems, the training has to be individualized.
Observation of the patient, particularly eye position and eye movements,
requires and experienced and skillful teacher to maximize results and
continue progress. When patients are frustrated and struggling, changing
techniques or exercises and encouragement by the therapist can make a
big difference. Correcting mistakes early can save time and promote more
rapid progress.
D.
Is my vision going to get better with all these exercises and training?
You may feel that your vision has improved because of gaining better visual
skills and use of an eccentric viewing position. Seeing a more complete
and clearer picture is a big advantage over what you experience when looking
at objects with the damaged part of your macula. The benefit is from maximizing
the vision you have, not from treating your medical condition.
E.
How does tracing help me see better and do my daily activities? It seems
like kindergarten work. What about other exercises?
Tracing may seem very simplistic but you may have noted how difficult
it is to perform accurately. This is a good measure of how well you can
use your eccentric viewing position. The eye hand coordination and use
of the new eye position will be a great advantage and benefit in performing
many daily activities because of the clearer and more complete picture
you will see. Repetitive exercises like tracing and identifying cards
help to develop this ability. Exercises are designed to improve the visual
skills needed to read, write and do many fine detailed tasks. It may also
improve your handwriting legibility.
F.
If I learn to use my eccentric viewing position, will it help me read?
Some people may be able to use an eccentric viewing position to read but
it is very individually determined. The amount of vision loss and location
of the blank spots (scotomas) in your vision affect the ability. Your
knowledge of the location of the spots and visual skills learned in the
training will definitely improve reading ability when coupled with appropriate
assistive devices. Short reading tasks will be easier than stories or
material with long sentences.
G.
Won’t it bother people when I look at them and I’m not looking
straight ahead? Eye contact is important when conversing with people.
Sometimes the eccentric viewing position is not off center enough to be
noticed. If it is more obvious, you may want to tell people that this
is your way of looking at them and seeing their facial expressions more
clearly.
H.
Why doesn’t the therapist give me a magnifier to use on the first
visit?
When you lose vision from a central scotoma (hole in your vision) that
interferes with fine detail tasks like reading, enlarging print may make
it easier to see print but harder to put letters and words in sequence.
Seeing only a word or two with a magnifier can slow reading to a point
of poor comprehension and make the process very frustrating. Some basic
visual skills gained under the guidance of a therapist before using devices
can increase your success.
