If you are curious about RGP contact lenses, you are on the right track to finding out about the cutting edge of corrective eyewear. That's because gas permeable (GP) contact lenses, also known as rigid gas permeable (RGPs) or oxygen permeable lenses, are light years ahead of the original hard contact lenses of yesteryear. When you get down to the truth about RGP contact lenses of today, you get down to serious medicine for people with vision difficulties.
The old-style hard contact lenses, which originally came out after World War II, were made of a material known as PMMA. Almost all contact lenses were made of PMMA before soft contact lenses came out in the 1970s. That's too bad for contact lens wearers back then. PMMA lenses were uncomfortable. Plus, when it comes down to it, PMMA lenses weren't too healthy for eyes because they didn't let too much oxygen in. That's one of the reasons scientists invented soft lenses and looked into the future about RGP contact lenses.
Speaking about RGP contact lenses, these gas permeable lenses first came on the scene in the 1980s. Instead of PMMA, RGPs are made from silicone, which is more flexible than PMMA. Silicone also allows oxygen to pass through the lenses. This means that RGP lenses are far more comfortable to and healthier for your eyes. RGPs even allow more oxygen to get through than many soft contact lenses. This makes your eyes happy on all counts.
What also excites doctors and users about RGP contact lenses is that overall they are more durable and resistant to protein deposits than soft lenses. Plus, they can actually help you see better. You'll find them easier to cleanse, cheaper to buy, and last longer. Still, RGPs aren't for everyone. They're 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 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.
