Contact Lenses for Dry Eyes
If you experience itching, or a burning sensation or even stinging in your
eyes, you might be experiencing what is commonly referred to as "dry eye" syndrome.
Indeed, perhaps you only experience a sensation of having "something in" your
eye, or some general discomfort. However, if you regularly have one or more
of these symptoms, it might well be due to dry eyes.
Having dry eyes implies that your eyes are not producing a sufficient quantity
of tears. In fact as we get older we all produce fewer tears,
and in some cases this can lead to dry
eye symptoms. It might also result because the composition of the tears has
changed, making them unstable and evaporating quicker.
Exposure to certain environmental conditions and medications such as
antihistamines, oral contraceptives or anti-depressants, can also contribute
to symptoms of
dry eyes. However dry eyes may also be a symptom of general health problems
or other diseases.
Contact lenses and dry eyes do not make an easy combination, since dry eyes
can make wearing contact lenses more difficult due to there being insufficient
tears to keep
the
lenses wet
and
lubricated. Thus dry eyes can lead to irritation and a greater chance of
eye infection.
Special Contact Lenses for Dry Eyes
However, recently great improvements have been made in contact lens materials.
In the past, many dry eye sufferers could not tolerate contact lenses at all.
Now there are numerous types of contact lenses, particularlyy ones
that contain the newest polymers, possessing molecules which attach to water,
allowing the
lenses to
resist deposits and function
better.
There have also been great advances in the recognition, diagnosis and treatment
of various types of dry eye. For example, patients with oil gland dysfunction
can tolerate contact lenses for extended periods of time through a regime
of warm compresses, lid scrubs and artificial teardrops.
Chronic dry eye patients can now wear their contact lenses more comfortably
thanks to high quality eye drops such as Restasis, a special
eye drop for treating chronic dry eye. Most dry eye patients
can
now
tolerate
contact lenses for at least eight hours per day, and patients formerly dependent
on glasses can now try the
latest technology in contact lenses, including multifocal lenses.
Some contact lens manufacturers specifically address the problem
of contact lenses and dry eyes. For example Biomedics offer Frequency
55 contact lenses for dry eyes. The higher water content in these
lenses can be of great benefit for those suffering from irritated
and dry eyes. If you need contact lenses for dry eyes, take time to
review and compare before selecting the best contact lenses
for your circumstances.
Many companies offer contact lenses for dry eyes and you should try to determine
the best ones in conjunction with your optician.
Solutions for Contact Lenses and Dry Eyes
There
are also solutions that are designed to work alongside contact lenses
and dry eyes to minimize risks and provide greater comfort. These include
tear inducing solutions and
artificial tears.
For these reasons, if you do appear to be suffering from dry eyes and wear
contact lenses or intend to wear contact lenses, it is important to discuss
your symptoms with your optician, who will then undertake a thorough examination
of your eyes and try to determine any underlying cause. It is important to
closely follow your eye specialist's proposed treatment plan.
During the examination, your eye specialist will ask about
your general health, use of medications, and work and home environments to
determine
factors
which may be contributing to dry eye symptoms. It might then be necessary
to perform dry eye tests.
In testing for dry eyes, your optician might use diagnostic instruments
that give a highly magnified view of your eyes, or sometimes small strips of
paper or thread
which together with special dyes, enable the assessment of the the
quantity and quality of your tears.
It is not possible to cure dry eyes completely, but
the sensitivity of your eyes can be reduced
and measures taken so your eyes stay healthy.
The most frequent method of treatment for dry eyes is the use of artificial
tears or tear substitutes. If you have a very severe case of dry eyes, ointment
can be used, frequently at bedtime. Sometimes tiny plugs may be inserted
into the corner of the eyelids to reduce the speed of tear drainages.
It is important that when undergoing treatment for dry eyes and you have increased
dryness or redness that is not relieved by the
prescribed
treatment,
you should inform your optician as quickly
as
possible.
