practice can fit all types of contact lenses, including specialty
lenses for those with astigmatism, bifocals, and hard to fit patients.
With our thorough fitting we can determine which contact lens is
best for your visual needs.
fitting involves tests and procedures beyond those performed during a standard
comprehensive eye examination. These specialized tests and procedures
will allow us to determine if your eyes are suited for lens wear. Your
eye and general health will be evaluated for any conditions which may
not allow for safe lens wear.
contact lens fitting will determine the
type and measurements of the most suitable contact lens for you. Our
goal is to find the best possible fit to ensure optimum vision,
comfort and safety with your new contact lenses. A series of important
follow-up visits have been designed to maintain continuous eye health,
accurate contact lens fit and optimum visual acuity. During these
visits, any necessary lens changes or prescription changes are
types of contact lenses are available?
lenses are generally categorized as "hard" lenses or
"soft" lenses. As the name implies, hard contact lenses are
manufactured from a rigid, clear material. Originally, hard
contacts were made from polymethylmethacrylate (PMMA), but modern hard
lenses usually combine PMMA with other plastics to increase the oxygen
permeability for better eye health. These new hard lenses are
called rigid gas permeable (RGP) contacts. Soft contact lenses are
made from a plastic hydrogel polymer, hydroxyethylmethacrylate (HEMA)
and have a high water content for added comfort.
addition to being categorized as either "hard" or
"soft," contact lenses may also be identified by their
"wearing" characteristics (extended wear, daily wear,
disposable, etc.) and according to the type of prescription (toric,
aspheric, bifocal, etc.). The following descriptions are those
generally used by the ophthalmic community in describing the various
types of contacts lenses.
wear soft lenses
These lenses are made of flexible, soft plastics that allow oxygen to
pass through to the eye. They are easy to get used to and comfortable
to wear. Because they fit close to the eye and are more difficult to
dislodge, they are often recommended for sports. They won't work to
correct all vision problems and may not provide the sharp vision
required by some wearers. They also require daily removal and
Disposable soft lenses are
normally worn for one or two weeks and then discarded. Disposable soft
contact lenses in general are a healthier lens choice when compared to
conventional daily wear lenses. Disposable lenses virtually eliminate
the experience of gradual deterioration, discomfort, irritation, or
eye infections from contact lens use. With disposables, you will
always experience fresh contact lenses. Not only are these lenses more
comfortable, they are more convenient and quite cost effective. They
are easy to get used to and comfortable to wear. Because they fit
close to the eye and are more difficult to dislodge, they are often
recommended for sports. They won't work to correct all vision problems
and may not provide the sharp vision required by some wearers. They
also require daily removal and cleaning, but they require less
cleaning than daily wear soft lenses.
wear disposable soft lenses
One day disposable contact lenses are the most exciting development to
occur in soft lenses in the last few years. Recent studies have shown
that the newer one day contact lenses are the safest soft contact lens
offered. It is the simplest soft contact lens solution - wear for one
day and throw them away. This is the best modality for patients who
are sensitive to solutions, wear lenses only for special activities
such as sports, have a history of contact lens infections or anyone
that wants the healthiest soft contact lenses. Wearing one day lenses
cuts out the average cost of $130 a year spent on cleaning supplies
for soft contact lenses.
replacement soft lenses
These contact lenses are replaced on a planned schedule, usually every
two weeks, monthly, or quarterly. They are available for most
prescriptions and require minimal care because they are frequently
Either soft or RGP lenses, these can usually be worn for up to 7 days
without removal. Because of the continuous wear, more frequent visits
to the eye doctor for follow-up care may be required.
Gas Permeable Contact Lenses (RGPs)
RGP's are one of the
healthiest contact lenses available because they allow for the passage
of oxygen and carbon dioxide through the contact lens, hence the term
gas permeable. RGP's are custom made for each eye and have the added
benefits of lasting sometimes 2-3 years and providing the clearest
wear rigid gas permeable (RGP) lenses
RGP lenses are manufactured from slightly flexible plastics that allow
oxygen to pass through. These lenses may provide sharper vision than
soft lenses and can be used to correct most vision problems. They are
also more durable and easier to care for, but often require a longer
Reduction RGPs (Ortho-K)
Myopic reduction lenses,
technically called orthokeratology (Ortho-K) are specially designed to eliminate near-sightedness during the day
without the need for glasses or contact lens wear. These lenses
are worn at night during your sleep and gently reshape the surface of
your eye so that when they are removed on awakening, you can see
clearly--without glasses or contacts! Your eye will hold its new
shape for perfect vision all day long. This option is perfect
for anyone who does not want the inconvenience of glasses or
contacts. Ortho-K lenses can also stop the fast
progression of near-sightedness in children. Click

Soft or hard contact lens that contain a single prescription power.
Premium contact lenses for borderline astigmatic patients and for
those who are just beginning to develop presbyopia.
Soft or hard contact lenses that contain both a spherical and cylinder
component to correct prescriptions that have astigmatism. These lenses
may be thicker in one area than another in order to maintain correct
orientation on the eye.
Like bifocal eyeglasses, bifocal contact lenses are designed to
provide sharp vision up close and at a distance. Several different
designs are available depending on the specific needs and adaptability
of the patient.
A term sometimes used in a special contact lens fitting technique that
is an alternative to bifocal contacts. Using this technique, the eye
doctor fits a near vision contact for reading in one eye and a
distance vision contact in the other. The technique is very effective
for some patients, but does require some adaptation and sometimes
results in compromised depth perception.
