RGPs (Rigid Gas Permeable) Lenses

“Hard” (PMMA) lenses were the original lenses that were first fit by Dr. Rod Small in the 1970’s. These lenses did not breathe at all and are now manufactured with a much more gas (or oxygen) permeable material. Now known as rigid gas permeable (RGP) lenses, these lenses can often provide better vision than a soft lens. They can be ordered to correct astigmatism and are also available for those who need a bifocal to correct their distance and near vision. Armstrong & Small Eyecare Centre is happy to continue to fit RGP’s and provide services for those who prefer this type of contact lens.
