Contact Lenses And You
Contact lenses are practically a new concept for most people. A
lot of people still prefer to wear glasses in order to correct
their own visual problems. But sometimes, using eyeglasses
present some disadvantages that need to be addressed. If a
person is regularly wearing eyeglasses of the ordinary sort, he
is likely more susceptible to glare and the occasional
reflective properties of glass that can greatly affect his clear
vision. Varying weather conditions might also affect eyeglass
wearers in a lot of ways. When it's raining, one's eyeglasses
can easily get hazy from the raindrops and can render it useless
in an instant.
On cold days, eyeglasses tend to fog up more often especially
when going inside warmer quarters. One will need to wipe it
frequently just to get rid of the moisture and get a clearer
vision on everything as well as to avoid being laughed at for
having fogged up eyeglasses. And one of the most despised things
about wearing eyeglasses is that it can make one look
unattractive. This is actually the frequent complaint of a lot
of many people out there. Such disadvantages may have persuaded
inventors to look for other alternatives in correcting vision
problems.
These disadvantages may have spurred the invention of the
contact lenses of late. With contact lenses, there is finally an
alternative which can do away with the drawbacks experienced
with wearing eyeglasses. Contact lenses make it possible for one
to finally improve one's vision without having to wear
eyeglasses. It can be such a welcome answer to people with
vision problems but do not want to wear prescription eyeglasses.
With contact lenses, it would be difficult for others to
recognize a person's vision problems unlike prescription
eyeglasses which is a plain giveaway in itself.
There are two types of contact lenses available for people. They
can choose either from soft contact lenses or the rigid gas
permeable types. Soft contact lenses can contain from 25 percent
to as much as 79 percent water which makes them soft and more
comfortable to wear.The rigid gas permeable contact lenses
meanwhile can take longer to get accustomed to. Its one
advantage is that it is made of a more durable material than
soft contact lenses and can offer crisper vision as compared to
contact lenses of the softer varieties. Rigid gas permeable
lenses are also more resistant to deposit buildup and tend to be
less expensive over the life of the lens when compared to the
softer versions which may even require frequent replacements.
The life of a rigid gas permeable contact lens can usually last
for a couple of years except when in need of a new prescription
pair. But with soft contact lenses, there is a need for regular
replacement of new lenses. There are soft contact lenses that
can be worn for a year before needing a replacement. There is
also the frequent replacement type of contact lenses which may
require you only one month of wearing before needing a new
replacement.
There are also contact lenses available that can be worn only
for short periods for convenience. These are the disposable
types of contact lenses. They are further divided into different
types depending on the level of convenience that you wish for.
There are daily and extended wear disposable contact lenses
which offer you a week or two of use before of disposing. For
the ultimate in convenience, there is the one day wear only
disposable contact lens which has virtually eliminated the need
for cleaning the lenses which can sometimes be a chore. But
disposable contact lenses can be very expensive for most to use
regularly except, that is, if you have money to burn and you
look for comfort and convenience more than the cost.
