Contact lens
Contact lenses have become increasingly
popular over the past couple of decades, due to the
introduction of soft contact lenses. The original contact
lens was hard and was subject to frequently
popping out of people's eyes; and to make matters even
worse, they were usually uncomfortable to wear for most
people. Today you can choose from a variety of contact
lenses that are not only comfortable to wear, but also
come for disposable and conventional use. You don't
need to have imperfect vision to wear contacts either,
but you should still have your eyes examined by your
eye doctor, so you can have your eye measured. This
will enable you to select the correct contact lense
that will be properly and comfortably fitted to you
eye.
The
two basic types of plastic contact lenses that you can
select from are rigid gas permeable or soft. They both
provide you with great vision, but the choice you will
make between the two, will depend on your eye condition
and your personal comfort. A rigid contact lens is harder
to adjust to than a soft contact lense, but they are
known to be more resistant and durable to enzyme buildup
that often takes place with conventional contacts. Rigid
contacts are also usually less expensive, and have been
known to provide people with sharper vision than soft
lenses. A soft contact lens is composed of 25-75% water,
and easily adjusts to your eye. For this reason many
people enjoy the feel of soft contact lenses over the
rigid gas permeable. Your choice between the two plastics
will rely heavily upon how frequently you wear your
contacts.
The two forms of contact lenses
that you can select from are disposable or conventional
(reusable). There are different options if you are interested
in using disposable contact lenses. You can wear a disposable
contact lens that is disposed daily, or invest in those
that are for extended wear - which can last up for one
to two weeks, or even a month. This extensiveness of
the wear depends entirely on the brand of contact lense
that you select. There are also contacts known as frequent
replacements. Frequent replacements can last for one
or several months, again depending on the brand; whereas
the conventional contact lens usually lasts for an entire
year.
No matter which contact lens
you choose, keep in mind that everyone's eyes produce
different amounts of enzyme, so the lifespan of your
contact will depend on your eyes and how well you take
care of your contact lens.
