Contact lens info:
If you want to wear contact lens instead of glasses, you must first see an
ophthalmologist, optometrist, or depending on the state, an optician. This
is the case even if you don't normally wear glasses, and just want
contacts just to change your eye color. The reason is because Contact lens
are medical devices that need to be properly fitted by an authorized eye
care practitioner. In the United States, contacts can be legally purchased
only with a valid written prescription from a credible doctor..
The eye doctor will check your eyes to make sure that it's
okay for you to wear contacts; today, nearly everyone can, but there are a
rare few people who actually can't. Then, he/she will determine what your
prescription is and make the recommendation from there. Your Contact Lens
Prescription Doctors all use the same method of shorthand to write down
contact lens prescriptions, and it can look like a secret code to the
untrained yes, but it's really quite simple to decipher to the trained eye.
This code is used to prevent unlawful fraud. The fact of the matter is that
if you wear contact lens without a prescription, you could severely damage
your eyes. Just like glasses, the wrong fitting lens could be harmful, but
the wrong prescription can cause life long damage.
 | What are my options ?
The selection of contact lens that are currently available can best be
described as wide. However, you don't have to worry about becoming
overwhelmed because contact lens can be broken down into several main
categories that are each based on what they're made of, how often you need
to replace them and whether or not you can sleep in them. Contact lens are
made of many different types of plastic, but they are divided into two main
groups: soft or rigid gas permeable. Soft contacts contain a great deal of
water in them and are easy to adapt to. They are also very comfortable to
wear. Rigid gas permeable contact lens take longer to adapt to because they
are a bit harder, but are more durable and more resistant to deposit
buildup. They are generally less expensive over the life of the lens but the
upfront cost is higher and they can offer some people better vision than
they would have with soft contacts because for some people they see things
more clearly. |
| The replacement schedule of a contact lens is a direct
reference to how long you can safely wear it before you need to throw it
away. With RGPs, you can generally replace them after several years of wear;
because they're so hardy. It doesn't make sense to replace them more often
than that. Soft contact lens come in a wider variety of replacement
schedules because there are also those that are disposable. The kind of lens
that you can sleep in is called extended wear lens, and those that you can’t
sleep in are called daily wear lens. |
| A great deal of companies these days are offering bifocal
and toric lens that are available in a daily wear lens. Many lens these days
also offer UV protection, but it is best to still wear sun glasses because a
contact lens only protects the cornea from UV rays and not your entire eye.
|
| Toric contact lens are made of the same material as regular
lens, but they do have great advantages. Toric lens are cheaper, they help
with astigmatism. These types of lens are a better fit for the eye, but they
can take longer to produce because they are form fitting to each person’s
eye. They cost more for purchase in the beginning, but they wind up being a
better deal in the end because they last longer and are easier to maintain.
When you are looking for the right contact lens choice, the best thing that
you can do is ask your eye doctor what choices are available to you and
decide from there. |
