Contact
Lenses and Dry Eyes
While Keratoconjunctivitis Sicca, or Keratitis
Sicca, or Sicca Syndrome, or Xerophthalmia, or simply Dry Eyes
(Syndrome) can be caused by innumerable factors, perhaps it’s most
common root is from extensive contact lens usage.
Yes, contact lenses and dry
eyes seem to come together, even with the best silicone
hydro gel contact lens in the market. As the contact lens sit on
the less sensitive tissues along the rim of the cornea, this could
also displace a volume of tears over the side to the sclera,
de-voiding the iris and the pupil a percent of tears. Over time,
tear displacements such as this will result to less and lesser
lubrication into critical areas of the eye, resulting to a syndrome
called dry eyes.
Another known effect is particularly associated
with the composition of soft lenses. These lenses have liquid in
their composition; when the liquid in its composition dries up, it
absorbs the lipids and moisture of the surrounding eye, drying the
eyes in the process.
Individuals who had contact lenses and
dry eyes do tend to exhibit similar symptoms: tired,
weary, and red eyes, itchiness in the central area, and a foreign
body sensation, akin to having a sandy grit in the eye. While using
rigid gas permeable contact lenses seems to prolong (if not save)
the user’s eye from the syndrome, contact lenses and dry eyes is
still as rampant especially if compounded with other causes.
Like old age. Ability to retain and develop
moisture naturally weakens with age, and dry eyes will be the
inevitable foe to aging users. For these aged users, conventional
rim glasses are more beneficial.
Medications like antihistamine also contribute
to dry eyes. These substances can upset automatic tear secretion
and locking moisture. So do ongoing or presence of diseases and
allergies: Sjogren's syndrome, rheumatoid arthritis, lupus, or a
combination of several or all factors.
So how do you counter effects of dry eyes?
Similarly, how do you diminish the chances of dry eyes occurrence.
Dry eyes, unfortunately, are irreversible. But the treatment of its
only symptom, the lack of moisture and lubrication in the eye can
be managed easily. Artificial tears like Tears Naturale Forte are
one of the readily-available solutions, though these eye products
only relieve for very short time. Ongoing symptoms is best used
with RESTASIS® (cyclosporine ophthalmic emulsion) 0.05% available
at www.restasis.com. This eye product boosts the natural ability to
produce tears.
Contact lenses and dry eyes,
while they do come in concert, cannot be treated together. The best
thing to do, when dry eyes symptoms come in full force is to remove
your lens, apply eye drops (and eye lubrications) and let it stay
without lenses for several hours.
