What
are
contact
lenses?
Contact
lenses
are
thin,
plastic,
prescription-engineered
discs
that
are
placed
directly
on
the
eye.
Contact
lenses
are
held
firmly
and
comfortably
in
place
by
the
natural
layer
of
tears
that
lies
between
the
lenses
and
the
surface
of
the
eye.
What
type
of
contacts
are
available?
There
are
numerous
choices
available
and
your
optometrist
will
discuss
all
your
options
after
a
thorough
eye
examination.
There
are
two
basic
categories
of
contact
lenses:
Rigid
and
soft.
Rigid
contact
lenses
(gas
permeable)
allow
oxygen
to
pass
through
the
lens
to
the
cornea.
They
are
ideal
for
patients
with
large
amounts
of
astigmatism.
Soft
contact
lenses
are
flexible
and
tend
to
be
more
comfortable
than
rigid
lenses.
Are
there
contacts
to
treat
Presbyopia?
In
addition
to
treating
near-sighted,
far-sighted
and
astigmatism,
presbyopia
can
be
treated
with
either
rigid
or
soft
contact
lenses.
There
are
bifocal
contact
lenses
that
offer
both
distance
and
close
range
capabilities
and
monovision
lenses.
Monovision
is
a
highly
successful
technique
that
involves
fitting
different
lenses
for
each
eye.
The
lens
in
the
dominant
eye
(determined
by
your
optometrist)
is
prescribed
for
distant
vision
while
the
non
dominant
eye
is
fitted
with
a
lens
for
close
vision.
Contact
lenses
offer
an
alternative
to
glasses
and
are
suited
for
people
with
active
lifestyles.
They
offer
similar
corrections
as
glasses
but
with
more
comfort
and
greater
peripheral
vision.
