Finding expert opinions on RGP contact lenses
There are many different opinions on RGP contact lenses, but most of them are highly commendable if you use the RGP lenses for their proper purpose. But, of course, proper and expert opinions on RGP contact lenses depend on having the facts before you start using them. So to form your own opinions on RGP contact lenses, start by learning exactly what are gas permeable (GP) contact lenses. I though we were talking about RGP lenses, you ask. Then you really do need a refresher course. You see, GP contact lenses are the same as RGPs, or rigid gas permeable lenses, and these are also the same as oxygen permeable lenses. Whatever you call them, they are the most high-tech "hard" contact lenses on the market at the moment. That’s where the good opinions on RGP contact lenses begin. RGP lenses should never be mixed up with the hard contact lenses of the old days. Then, hard contacts really were hard -- hard to wear, put up with, and live with on a long-term basis. Old-time hard contact lenses were made of a material called PMMA. PMMA lenses were uncomfortable to wear and difficult to put in and take out. What’s worse, PMMA didn’t allow oxygen to pass through to your eyes. Just like every part of your body, if not more so, your eyes need oxygen to be healthy. What makes opinions on RGP contact lenses so high, on the other hand, is that they are made with silicone, a compound that’s far more flexible than PMMA. Plus, silicone allows oxygen to permeate, or pass through, to your eyes. Believe it or not, but RGP lenses allow more oxygen in to your eyes than your standard soft contact lenses. Both of these factors lead to much easier use, better comfort levels, and healthier eyes. Just wait. Your opinions on RGP contact lenses will get even higher when you consider that they offer better visual sharpness, durability, and deposit resistance than soft contact lenses, as well. To top it off, they can clean easier, last longer, and cost less in the long run. You can even have RGPs polished by a skilled eye specialist to add even more value to them.
