RGP Contact Lenses
The hard contact lenses of today have improved significantly since your parents' and
grandparents' hard contact lenses. Today, hard contact lenses are made of a material that
incorporates both silicone and fluorine, making it
strong and durable, but also oxygen permeable (breathable) and
resistant to deposit build-up. As a result, while RGP lenses tend to be much thicker than soft
contacts, they are comfortable and safe to wear because the eye can easily still obtain oxygen from
the air, through the lenses. RGP contact lenses are also extremely long-lasting, with a replacement
schedule of around 1 year. They are also very inexpensive.
The Adaptation Period
Despite its advantages, RGP contact lenses are
very difficult to adapt to - a typical adaptation period lasts about 10 days. What does this mean?
Basically, for the first ten days that you wear your RGP lens, you will feel like you have sand in your
eyes. It's uncomfortable - to say the least! For this reason, RGP contact lenses are
generally reserved for people with high amounts of
keratoconus. These people stand to benefit
the most from RGP lenses while people who do not have astigmatism (or have mild to moderate
astigmatism) have the much more versatile option of wearing
toric or spherical soft contact
