Rigid Gas Permeable (RGP) Lenses

       Rigid Gas Permeable (RGP) lenses are made out of a ‘rigid’ plastic material as the name implies.  These lenses are much more breathable and healthy for the eyes than the earlier models such as the “hard” lens. The hard lenses were made out of a PMMA material that had virtually no oxygen permeability, and are rarely ever used anymore.  The more recent Gas Permeable lenses are far superior, and provide excellent optics for superior clear vision.
       With the advent of ‘soft’ contact lenses, fewer people are being fitted for RGP lenses due to their discomfort.  However, many people that are used to them choose to continue wearing them for various reasons.  Such reasons include:

  • Pristine visual clarity
  • Affordability
  • High amount of Astigmatism that cannot be corrected as well with soft toric lenses
  • Medical necessity due to conditions such as: keratoconus, or post-surgical corneal abnormalities.

       Most RGP lenses should be replaced every year, or every other year at the latest.  This replacement schedule will keep your eyes much more healthy and free of harmful protein buildup or bacterial accumulation.  Much like spectacle lenses, RGP lenses will usually become fairly scratched over time, and may cause irritation and poor vision.
      
      We have a vast number of these RGP lenses with various parameters in stock, and in many cases can give you a lens to leave our office wearing!  Not many practices can offer that same convenience.   If by chance we don’t have the lens you need, it usually takes only a few days to order it in.  Schedule an appointment today for a comfortable fit.
