Over 40 (presbyopia)
Presbyopia is a natural part of the aging process and affects
everyone over forty years of age. People usually notice the
condition around age 45, when they realize that they need to
hold reading materials further away in order to focus on them.
The process by which the eye increases its power to see things
clearly close up is called accommodation. Accommodation can
be described as the "auto focus" feature similar to that on
a camera. Just as a camera lens needs to be moved back and
forth to focus clearly on the object being photographed, an
eye adjusts its power to focus on things up close or in the
distance.
As presbyopia starts to develop, the eye power becomes a "fixed-focus" losing
its ability to "auto-focus" on things at different distances,
providing clear vision only at a particular distance. If the
vision is corrected for distance, seeing things close up becomes
a challenge with the distance vision correction. The reverse
also holds true. When the vision for close up distance for
people with presbyopia is corrected, distance vision will be
blurred.
The unique Duette™ Multifocal hybrid design
eliminates the instability and soft optics issues of other
multifocal contact lenses. You'll never have to juggle multiple
vision solutions - glasses and bifocals, or bifocals and contacts - again.
The precision rigid gas permeable center and the soft contact
lens skirt of the new revolutionary Duette™ Multifocal hybrid
contact lens provides clear, crisp, consistent vision at distance
and close up. The irregularities of the front surface of the
eye that are typically transferred to the front surface of
a soft contact lens are neutralized by the tear film between
the eye and the rigid gas permeable center. All nearsightedness,
farsightedness and astigmatism are corrected by the distance
power, while the crisp optics of the close up power provides
simultaneous computer and reading vision with minimal interference
with distance vision. With the Duette™ Multifocal contact
lens, now you can experience ageless vision near and far.
If you are experiencing blurry vision while reading because
of presbyopia and want to experience ageless vision near and
far and clear, crisp vision when looking at things close up
or at a distance, ask your eye care practitioner about the
Duette™ Multifocal lens.
