Ive
never worn contact lenses before, how do I start?
First you need to have a current eye exam so that we know your
eyes are healthy, as well as, your prescription. Then you need
to have a new contact lens fitting, which involves having the
doctor measure the shape of your eye and choose the contact lenses
that are best for you. You will be trained how to put the contacts
in and out of your eyes, as well as how to clean and care for
the contact lenses. The doctor will evaluate the fit of the contacts
and if everything is fine, you wear the contacts home. If you
are happy with wearing contact lenses after you have worn them
for a while, you can order a six month or yearly supply.
Why
use disposable contact lenses?
Most people are fortunate to be able to use disposable contact
lenses because they are healthier than conventional contacts.
Conventional contacts refers to a soft lens that you keep for
a year.
Disposable
contact lenses are either worn for a single day, or two weeks,
a month, or two months before they are thrown away. The disposable
contacts allow more oxygen to transfer through the lens to your
eye and they are easier to keep clean. Both these features make
the disposable contacts healthier and more comfortable than conventional
contacts.
What
is the difference between soft and hard contact lenses?
Today most people use soft contacts as they are the most comfortable
initially. They are also easy to care for and can be used to correct
almost all prescriptions.
Hard
lenses are also called rigid gas permeable or RGP. They are custom
made to the shape and power of your eye. It often takes about
a week to become completely comfortable with your first pair of
RGPs. They are very healthy and give good vision. These lenses
are usually recommended for people who are very nearsighted.
How
do I know when to throw away my contact lenses?
Your optometrist will tell you how long you can wear your contact
lenses. That length of time is determined by the contact lens
material, the cleaning system and your tears. The contacts should
still feel good at the time you are to dispose of them. If they
feel bad, you have worn them too long and your eyelids and cornea
are being irritated by the debris on the contacts. As you wear
the contacts there is a film of protein and lipids from your tears
that gets deposited on the lens. This film reduces the amount
of oxygen that can get through the contact lens to your eye and
that is why you need to throw away your lenses according to the
schedule.
Can
I sleep in my contacts?
Most contact lenses do not let enough oxygen through them to allow
you to sleep in them. This is because the eye receives less oxygen
when the eye lids are closed. However, silicone contact lenses
such as Pure Vision can be worn while sleeping because they allow
five times more oxygen transmission compared to ordinary soft
contact lenses. Pure Vision contacts are designed to be worn continuously
for one month and then replaced with a new contact lens.
Can
I swim in my contacts?
It is best not to wear contact lenses while swimming as your risk
of an infection becomes much higher. The contact lens also absorbs
chlorine and your eye will be exposed to the chlorine for many
days afterwards. If you do choose to wear contacts while swimming,
you should wear swim goggles and use a daily disposable contact
lens which you throw away after swimming.
Do
my contacts block UV rays?
Some soft contact lenses block ultraviolet rays, and others do
not. You should ask your optometrist, or check on the box to see
if it says that the contacts are UV blocking. When contacts do
block ultraviolet rays, they do not stop the glare or brightness
of the sun and so you may still choose to wear sunglasses over
top of your contact lenses.
How
do I clean my contacts?
To properly clean a contact lens, you remove it from your eye,
place it in the palm of your hand with a few drops of solution.
Gently rub the contact with one finger against the palm of your
hand for approximately 10 seconds. This removes any protein and
other particles that have become attached to your lens while you
were wearing it. Next put the contact lens in the case and fill
the well with solution. Contact lens cases are designed to hold
exactly the amount of solution required to disinfect one contact
over a period of 6 to 8 hours. Repeat the procedure with the second
contact lens. It is best to always start with the same eye so
that you can keep track of which lens is for the right eye and
which is for the left eye. In the morning, remove the contact
lens from the case and insert it into your eye. Empty the case
and leave it to dry until needed again. Your contact lens case
should be washed once a month. Simply use hot soapy water, rinse
with water and then rinse with contact lens cleaner.
What
is the best contact lens cleaning solution to use?
For soft contact lenses the best cleaning system is Clear
Care. It is a peroxide based cleaner which disinfects
much better than solutions that use soaps.
For
RGP contact lenses the best cleaning system is Boston. This involves
a cleaner, a conditioner and use of an enzyme cleaner weekly.
Whats
up with No-Rub contact lens cleaners?
You may notice that some of the MPS solutions now say No
Rub. This was given FDA approval with the instructions being
that instead of rubbing the contact lens, you squirt a steady
stream of solution at the lens for 10 seconds on each side. You
will find that it is faster, more effective at cleaning and less
expensive to simply rub the contact lens.
