What is so great about RGP contact lenses!
By Garry Allen
So, I have your interest and you want to know more about RGP contact lenses.
Well good, you are now on the right track to learn more about the cutting edge
technology of this corrective eye wear.
Gas permeable (GP) which are also known as (RGP) rigid gas permeable and
oxygen permeable lenses are literally light years ahead of the old hard contact
lenses.
When you get right down to the bottom line truth about RGP contact lenses,
you are getting down to some really serious medicine for people with vision
difficulties.
Let's first talk about the old style hard contact lenses. Remember those!
These contacts originally came out in 1945, and were made with a material known
as polymethyl-methacrylate (PMMA), boy that was a mouthful.
Now as I was saying, PMMA which is an emorphous thermoplastic with good
optical qualities was used in just about all contact lenses prior to the soft
lenses hitting the market in the 1970's.
Which unfortunately for contact lense wearers back then was very
uncomfortable and very difficult to get used to if you could.
But not only that! PMMA lenses was just not healthy for your eyes because
they did not allow oxygen to pass through. Now this is one of the main reason's
scientists invented soft lenses and looked into the future about RGP contact
lenses.
Ok, out with the old and in with the new.
Let's talk about RGP contact lenses now. Gas permeable lenses first came out
in the 1980's. Now instead of PMMA, RGPs were made from silicone, which is more
flexible than PMMA and more importantly they also allow oxygen to pass through
the lenses to the eye.
This is vitally important for healthy eyes.
Now keep this in mind also, RGP contact lenses even allow more oxygen to get
through to the eye than many soft contact lenses.
So the bottom line is, not only are RGP contact lenses more comfortable to
wear but they are healthier for your eyes. This makes your eyes happy on all
counts.
Now if that wasn't enough here is another benefit of RGP contact lenses that
doctors and contact lense wearers are excited about and that is RGP contact
lenses are more durable and resistant to protein deposits than soft lenses.
Plus, they can actually help you see better. You'll also find that they
are easier to clean, cheaper to buy, and last longer.
But...there always has to be a but somewhere doesn't there...
Still as beneficial as RGP contact lenses are, they are still not for
everyone.
They are best for people who have trouble getting great results from regular
soft lenses. These could include people who are just very picky when it comes to
their vision.
Or for people whose eyes have certain disorders that makes vision
correction more difficult. This includes sufferers of astigmatism, who
often find soft contacts lacking when it comes to vision correction.
