subject: Rgp Contact Lenses-real Good Choices For All [print this page] Though people tend to wear soft contact lenses, available are some other much better lenses- RGP, abbreviation of rigid gas permeable. In the past, contact lenses were made up of PMMA, a sort of hard material. Later, silicone is used to manufacture better contacts which are gas permeable with more comfort.
In fact, contacts made up of RGP will not only let through Oxygen, but also help maintain eye health. Still, those lenses can provide much better vision to users. The reason is very simple- those silicon lenses will not move as people blink or move eyes; they will also help maintain eye shapes. Generally, RGP are relatively cheaper than ordinary soft contacts.
It is true that eyes will adapt to common contact lenses quickly, but not so in RGP. Different users will spend different time in getting used to them.
There is always a phenomenon that some users of RGP think those lenses are hard to adapt and they reuse soft lenses again. Doing so will make the adaptation much harder. Or some people may suffer from vision blurriness if not wear RGP, but other glasses. Anyway, RGP are really good alternatives for people with eye problems, in particular those with astigmatism. Also, those lenses can also be used as bifocals.
