What is so great about RGP contact lenses!
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
