Top Ten Things You Should Know About Contact
Lenses
by Alex Fir
1. Soft lenses are perceived by most patients and
practitioners alike to be more immediately comfortable while adequately
correcting vision. They come in all formats — even toric and
bifocal. Disposable soft lenses take minimal but important care to
maintain their safety and usefulness.
Soft lenses do absorb elements from the tears and the environment. They
can change in fit with their age and cleanliness, perhaps causing a lack
of oxygen to the eyes. Their surfaces
break down rapidly, causing a decreasing sharpness of vision.
On the other hand, many patients feel they see sharper and more clearly
with rigid gas permeable (RGP) lenses. RGPs become very comfortable
after adapting to them. They are easier and less expensive to maintain,
last longer and are available in all formats. RGPs can
more easily be custom designed to offer a wider range of vision
correction than soft lenses. They can breathe more oxygen, don't
deteriorate as fast and don't absorb things as easily as soft lenses.
2. Soft lenses generally center by themselves if they fit well. Just put
them straight on the cornea and they will go where they belong. Use the
iris, the colored part of the eye, as a
guide. Make sure you have a competent eye care practitioner evaluate the
fit of your lenses before you wear them, though. Improperly fit soft
lenses can cause damage to your eyes!
3. Almost all nearsighted people can wear contact lenses, no matter how
high their prescription. In fact, there are contact lens laboratories
that make custom lenses up to -30.00 diopters! It is essential to follow
your contact lens practitioner's rules, however.
Contact lenses are extremely safe when prescribed and cared for
properly.
4. Improperly worn contact lenses can cause a loss of oxygen to the
cornea, which in turn can lead to blood vessels growing over the front
of your eyes, infections, lid changes, allergies, corneal warping,
corneal swelling and possibly even blindness.
5. Do not share contact lenses with your friends. Everyone's tears are
filled with normal bacteria, but transferring these bacteria to someone
else's eyes is not a good idea. And not
only is there a risk of infection, if the lenses don't fit, the eye can
suffer from a lack of oxygen or develop other problems.
6. Contact lenses are medical devices. Changing parameters should be
done under the supervision of an eye care practitioner. Do not take
chances!
7. If you sunbathe while wearing contact lenses, there is no problem
with heat. But your corneas can swell and make your lenses fit tighter,
causing some temporary redness and
irritation. Put some form of lubricating drops in your eyes before
tanning. Wear protective glasses to block the really harmful UV
radiation from getting to your eyes — it has been linked to cataracts,
macular degeneration, etc.
8. Bloodshot eyes are a sign that something is not right. It could be as
simple as a solution allergy or dirty lenses. But it could also be a
sign that your corneas are not getting enough oxygen. Go see your eye
care practitioner and find out why your eyes are so red!
9. Eyeglass prescriptions are higher than contact lens prescriptions
because contact lenses sit on the eye, whereas eyeglasses sit in space
in front of the eye. This is called the vertex
distance. The closer a lens sits to the eye, the less strength is needed
to focus light on the retina. And the stronger the prescription, the
more the power adjustment. This is true for
both soft and RGP lenses.
10. Some contact lens practitioners find that lenses with lower water
content can sometimes be better for people who have dry eyes. But some
patients actually do better with high-water contact lenses. It has long
been felt by some practitioners that the thicker the lens, the better,
as well.

Valuable Tips To Finding Cheap Contacts Online
by William Lezubski
When searching the Internet for cheap contacts,
you may feel like you're trekking through a jungle of contact lens
suppliers, and as you stumble on their contact site, they all claim to
be offering cheap contact lenses for the lowest prices, or so it would
seem!
Some may even provide incentives such as free solutions, contact lens
cases, and even free shipping to get your business. So how do you decide
on the best company to deal with, and how do you actually know you're
getting the best lenses online for the cheapest price?
The only way you can find out if your getting the best deals is to
search each individual lens business online, and do some
comparison-shopping. We will provide you 3 tips that may help you find
the best bargains on contacts, and help you maximize your savings.
When searching for contacts online buy only from reputable suppliers
Tip #1: Even though the site you land on may claim they have cheap
lenses, make sure they're a reputable and well known company! You want
to buy only from trustworthy online suppliers that offer name brands
like Acuvue, Bausch & Lomb, Freshlook, CooperVision, or Biomedics. They
will offer you fantastic discounts on top brand lenses, due to their
significant volume of lenses they sell over the Internet.
Tip #2: Other contact lens companies that discount will say that when
you purchase their cheap eyewear, that their savings will generally be
up to 80% off retail. However, do they offer free shipping, or do they
have price guarantees if you happen to find your contacts at a lower
discount price somewhere else. Also make sure they have a policy in
writing for returns, and detailed instructions for replacements. If they
don't honor returns, then you will be stuck with a product you don't
need, and what kind of savings is that!
Tip #3: Many so-called suppliers will offer you a really attractive
contacts discount on your first order, but if you're planning on
purchasing a disposable lens, you want to make sure the next time you
place a re-order, that you're going to receive the same prescription
price you paid the first time. Find this out before placing your order,
and get it in writing that the cost will stay the same.
Companies we have come across that have earned a reputation for the
finest lenses at competitive discount prices are 1-800Contacts,
TheContactLensesStore, Lens.com, ACLens, and DiscountContactLenses to
name a few!

How To Choose The Right Contact Lenses
by Peter Smithson
Today's contact lenses are used to correct
specific vision
problems or to change eye color. With all of the advances
in technology, more people than ever before are able to
wear contacts. There are a variety of lenses available
including disposable, extended wear, flexible war, and gas
permeable and even contacts for special needs.
You can change or enhance your natural eye color, even if
you don't require vision correction. With color altering
lenses, you can achieve just the right look for a costume
or simply a magical pair of green eyes that will look
spectacular with a new dress. It gives a whole new meaning
to the lyric 'don't it make my brown eyes, blue.'
Disposable lenses are perfect for the person who doesn't
have time to do daily care and cleaning of their contacts.
Depending on the brand your optometrist recommends, you can
choose either a daily disposable or one that will last one
week or two weeks.
Disposables are exactly what their name implies; you take
them out and throw them away each day. Conveniently,
disposables are available for different eye types now
including those with astigmatism and if you were looking to
try out colored contacts for a while, disposable lenses
come in varying shades as well.
Gas permeable contacts are designed for people who require
a very specialized prescription. In some cases,
astigmatisms on the eye make it very hard to fit the
candidate with the right level of correction. A person
whose vision is 20/180 may not correct to 20/20 with other
types of lenses. Gas permeable is more expensive, but the
ultimate decision lies between the optometrist and the
patient.
Flexible wear and extended wear lenses are designed for
those who like to be able to sleep in their contacts rather
than deal with putting them in and taking them out several
times a day. These are especially useful for those who
travel a great deal or are frequently away from home. No
worries about having to carry your lens cleaning kit with
you everywhere you go.
More than 30 million people wear contact lenses and it
requires a visit to your eye care professional that can
then determine if you're a candidate for contacts. With so
much variety and so many advances, the chances are good
that your local optometrist has the right contact lens for
you.
