Rigid Contact Lenses

Rigid Contact lenses, sometimes known as PMMA (hard lenses) are slowly becoming a material of the past.

Gas Permeable lenses (also known as semi-soft) are now the materials of choice for certain types of prescriptions. These lenses are replacing the old HARD type (PMMA) because they can be designed thin, they allow much more oxygen to the cornea and even allow a little flexing which helps with healthy tear exhange.

Like soft lenses, there are many brands on the market and they take expertise to fit properly. Boston Materials are one of the largest gas permeable manufactureres in the world. Listed below is a little information on this material.

More oxygen means healthier eyes.
Some contact lenses let more oxygen reach eyes than other lenses.That's because they're crafted from a patented, oxygen permeable material that allows more oxygen to pass through the lens. That's important because your eyes need oxygen to breathe freely - the way healthy eyes should.

 

Designed for excellent vision.
Each contact lens design is unique. What makes them even more exceptional is that the lenses are custom fit to the natural shape of your eyes. That's something you won't find with soft or disposable lenses, and it can make a world of difference for people with astigmatism.
Unlike water-based soft lenses that can dry out, tighten up and lose their shape over time, Some lenses are made from a material that retains its shape, providing long-term crystal-clear vision. And because their ultra-smooth, nonstick surface resists dirt and debris, they're easy to keep clean. These lenses let more oxygen reach your eyes to keep them healthier
