Bifocal and Multifocal Contact
contact lenses are not really bifocals any more. The vast majority
are "multifocal" which means they have an infinite
amount of focusing between far and near.
Hold the book up close and the words
appear blurred. Push the book farther away, and the words snap back
into sharp focus.
That’s how most of us first
recognize a condition that eye care professionals call presbyopia, a
name derived from Greek words meaning "old eye." Eye
fatigue or headaches when doing close work, such as sewing, knitting
or painting, are also common symptoms. Because it is associated with
aging, presbyopia is often met with a groan -- and an expectation
that reading glasses or bifocals are inevitable. Until recently this
was true, however CIBA Vision's Focus® Progressives soft contact
lenses can provide individuals with presbyopia, clear and
comfortable vision at all distances without the hassles, vision
jumps and distortions typical of bifocals or reading glasses.
As we age, body tissues normally lose their elasticity.
As skin ages, it becomes less elastic, and we develop wrinkles.
Similarly, as the lenses in our eyes lose some of their elasticity,
they lose some of their ability to change focus for different
distances. The loss is gradual. Long before we become aware that
seeing close up is becoming more difficult, the lenses in our eyes
have begun losing their ability to flatten and thicken. Only when
the loss of elasticity impairs our vision to a noticeable degree do
we recognize the change.
How is presbyopia treated?
Traditionally eye care practitioners prescribe bifocal
spectacles or reading glasses to help the eye accommodate for
close-up work. However, soft contact lenses such as CIBA Vision's
Focus Progressives are rapidly increasing in popularity as an
exciting new alternative for people with presbyopia.

What lens option will
work best for me?
Your eye care professional may ask a number of questions
to help determine the best avenue of treatment. You may be asked to
describe your usual lifestyle or daily activities and from this your
practitioner will be able to recommend a solution most suited to
your needs. For instance, if you are a librarian, your needs will be
significantly different from those of a truck driver.
Once my vision is corrected for presbyopia, will I
require frequent lens changes?
Presbyopia is a gradual change, happening over a number
of years so your prescription will need to be updated periodically.
Changes are best made at your regular eye examination rather than
after the need for change starts to cause you difficulties.
