Rigid Gas Permeable Contact Lenses
Rigid
Gas Permeable contact lenses (RGP lenses) are worn
by about 15 percent of contact lens wearers. Unlike
hard plastic lenses, RGP lenses are gas permeable.
That is, they allow oxygen to pass through to the
cornea. They are less expensive and more durable than
soft contact lenses, and provide wearers with clearer,
sharper vision.
Unlike soft contact lenses, RGP lenses have a low
water content and therefore, resist protein deposits
and bacteria. Because they are rigid, they hold their
shape when the wearer blinks, allowing for crisper
vision. Other benefits include ease of handling and
ease of care. Because they do not contain water,
proteins from the eye do not build up on the lens, so
the lens stays cleaner, and requires less maintenance.
RGP's are not for every patient. Because of their
rigid form, they require more break in time for the
patient to become comfortable with wearing the lenses.
Also, if you discontinue wearing your RGP lenses for a
few days, it may be difficult to become used to
wearing them again. RGP's differ from soft contacts in
that becoming comfortable with wearing a rigid lens
requires the patient to wear their lenses all the
time. Soft contact lens users may discontinue wearing
their lenses for a few days, and immediately be
comfortable with having them inserted again.
Rigid Gas
permeable contact lenses are also known as Oxygen
Permeable contact lenses. The plastic of these lenses
is breathable, and they must be custom fit to the
shape of the cornea. Only your eye care professional
can help you decide which contact lenses are right for
you.
