Bifocal Contacts
Bifocal Contact lenses - What are they?
Bifocal
contacts are sometimes referred to as segmented contact lenses.
Typically, the top portion of bifocal contacts is used for distance
vision, and the bottom portion for near or reading vision. Bifocal
contacts provide alternating vision aid for those needing both near
and distance vision correction.

Bifocal contacts are specifically fitted to an individual's eyes.
Bifocal lenses are specifically suited to those individuals
suffering from presbyopia. These lenses are available as both
soft
contact lenses or gas permeable contacts. Today, bifocal contacts
are available as disposable lenses or frequent replacement wear
lenses. Daily disposable bifocal contacts are rapidly becoming the
most popular bifocal contacts on the market today.
About Bifocal Contact Lenses
There are several different designs of bifocal contacts. These
include;
a) concentric design - typically, the near vision correction
is in the middle, and the distance vision correction is on the
outside of the lens
b) aspheric design - both near and distance vision correction
rests close to the pupil
c) translating design - near vision correction rests at the
bottom of the lens, and distance vision correction lies at the top
Another variation in bifocal contact lenses is how the vision
correction is achieved. In some situations, the contact lens will be
much like bifocal eyeglasses, with two different prescriptions
divided at the halfway point in the lenses. Others blend the
different prescriptions across the lens, much like progressive
eyeglasses.
The various designs of bifocal contact lenses offer different
features and benefits. Only your eye care practitioner can decide
what bifocal lens is best for you.
The most common use of bifocal contacts is to treat individual with presbyopia.
About Presbyopia
Presbyopia refers to the difficulty of focusing up close. As with the rest of our bodies, eyes and vision age. For those who already wear corrective lenses for astigmatism, near or far sightedness, the development of presbyopia demands bifocal contacts or eyeglasses for vision correction.
Presbyopia develops when the lens of the eye becomes thicker and
more rigid. This thickening affects the ability of the lens of the
eye to change in curvature to respond to the need for near or
distance vision. As a result, images focus behind the retina,
instead of on it, causing close up vision to be blurred.
The development of presbyopia is most common in individuals over the
age of 60. Regular eye exams after age 60 are critical. Seniors are
advised to see an eye care specialist every 1 - 2 years.
Your eyes are your window to the world. Never take your vision for
granted and regularly visit an eye care specialist to ensure that
your vision is as healthy as it can be. Bifocal contacts may be an
excellent answer to your vision needs. Those wearing bifocals can
