Contact Lenses – Bifocal or Multifocal?

Contact Lenses Bifocal or Multifocal?

In order to create clear near vision, your eye
increases its power though a process known as
accommodation. This process is fairly similar
to what a camera lens does in order to focus on
objects close to the camera lens. Presbyopia is
a condition in which the eye is not able to
complete the process of accommodation
successfully and is normally a result of aging.

Until recently, glasses, were the primary
solution that was offered. However, with
recent developments there are now a variety of
different solutions provided by contact lenses as
well. Here is a quick look at exactly what
this condition is and certain types of contact
lenses can provide a solution.

As a person ages, their eyes naturally start to
lose the ability to successfully increase power
by the eye, thus the process of accommodation can
no longer take place. In most cases, this does
not start to happen until a person hits 40 years
of age and the first symptom is normally most
noticeable as reading becomes more uncomfortable.

A presbyopic eye will still be able to see some
objects completely clearly, however some objects
will start to blur. Essentially, the eye enters a
fixed state of focus. This means that at
certain distances the eye is perfectly suited to
create a clear picture (many times the vision
will even be 20/20), however at any other
distance, the images will bur.

Before contact lenses were used as a solution to
this problem, people were forced to rely on
either bifocals or traditional reading glasses.
There are a variety of different contact lens
options available today. The two most popular
are mono-vision lenses and multi-focal lenses.

Both options have proven to carry specific
benefits and drawbacks and without understanding
what each of these options actually provide,
making a decision can be difficult.
Fortunately, the differences are easy to
understand once you realize what they are and the
specific contact lenses work. Here is a closer
look at the differences between bifocal and
multifocal contact lenses.

The most fundamental difference is that bifocal
contact lenses have two prescriptions within the
same lens. Multifocal contact lenses carry a
range of different powers in each lens, which is
similar to a progressive lens that is used in
glasses.

It is important to use this differentiation,
because some people will use multifocal as a
catch-all that includes any lens that has more
than one power (including bifocals). Overall
there are 2 basic designs for lenses that treat
presbyopia Alternating and Simultaneous.

The alternating vision design forces your pupil
to alternate between two different powers by
changing your gaze upwards or downwards. This
design is specifically used for bifocal contact
lenses, however there have been some trifocal
lenses that have tried applying this same
strategy.

If you are having problems imagining how this
type of lens works, take a moment and picture a
traditional pair of bifocal glasses. Those
lenses function the same way that the alternating
design bifocal contact lenses do. The reason
that some people feel that this option is the
best is because you are in total control of which
power you are using.

These types of contacts are normally smaller than
traditional soft contact lenses and instead of
moving with your eyes, they stay fairly
stationary. This allows your eye to easily move
from one power to another.

There are two different types of simultaneous
designs for presbyopia. The first is the
concentric ring design. The concentric ring
design is primarily for bifocal contact lenses.
With this design, there are two rings of
different powers that lie within your pupil area.
The center can be either near or far vision
powered and the decision is normally up to you.

To best imagine this type of design, try to
imagine a dartboard. Now imagine that each ring
alternates between near and far vision.

The other type of design is the aspheric
multifocal design. These contact lenses work
the same way that progressive eyeglass lenses
work. There are a range of different powers that
are all spread out and blended across each lens.

While this has proven to be extremely effective,
it is important to note that it will take some
time for your brain to learn to choose the
correct prescription level for any given moment.

Because of the vast array of options that you
have to choose from, trying to decide between
bifocal and multifocal contact lenses can be a
difficult one. Many people suggest that the
best idea is to test out a variety of different
options until you find the right fit for your
specific needs and comfort.

As contact lenses continue to become the more
popular option, there will continue to be
improvements in regards to creating and improving
additional multifocal solutions.
