Choosing contact lenses
By Jeff Lakie
Many people are switching to the freedom and convenience of contact
lenses. If you're thinking of switching from glasses to contact lenses,
here are often several questions to ask:
Question: Why would I want to switch from glasses to contact lenses?
Contact lenses can be a lot more work than glasses because
they require to be cleaned and disinfected periodically.
However, contact lenses allow you to wear sunglasses, if you
want. They are also ideal for people who want to play sports
but whose glasses could potentially be damaged during play.
Question: What kind of contact lenses are there?
There are different kinds of contact lenses. You can choose
soft contact lenses or hard contact lenses. Hard contact lenses
need to be worn regularly in order to keep your eyes used to
the shape and feel of the lens. But you can't wear hard lenses
for too long at one time because some hard lenses are non-
permeable and do not allow oxygen to get to your eyes.
Check with your optometrist if you have hard lenses to see
how long they recommend you wear them for.
Soft lenses vary greatly. Some are for daily use. Others can be
worn for a few days before they need to be removed. Talk to
your optometrist about the different options available since you
may find that one kind is better for you than another.
Question: How much work are contact lenses?
Disposable lenses are available and an excellent alternative for
someone who does not have the time or inclination to care for their
contact lenses. These can be worn once and discarded, or some of
them are designed to be worn for several days before being thrown
out.
Question: I don't have a standard prescription, can I still wear contact
lenses?
Even if you have an astigmatism in your eyes, recent
developments in contact lenses will allow you to wear contact
lenses. And, if you require a bifocal prescription, there are
bifocal contact lenses available!
There are enough advancements in the contact lens industry to allow
just about anybody who wants to switch over to contact lenses to
make the leap.
