Rigid Gas Permeable Contact Lenses

Home  >> Other Contact Lenses

There are two basic types of contact lenses on today’s market – soft contact lenses and the rigid gas permeable contact lenses. Both are designed as alternatives to conventional eyeglasses and offer vision correction for a wide spectrum of patients.
Soft Contact Lenses are larger and flexible, they need to be kept wet in order to maintain their shape. These lenses are designed for immediate comfort and wearability. These lenses are often disposable, convenient in that they do not need to be cared for or maintained but can be worn once, or for a few weeks, and then disposed of without thought.

Soft Contact Lenses

Rigid Gas Permeable lenses are smaller and harder, maintaing their shape even when dry. RGP lenses offer patient’s sharper vision (particularly for patient’s suffering from astigmatism) than the soft contact lenses. Although RGP lenses often require a longer adaptation period, these durable lenses can last for up to three years with proper care and maintenance.
Both RGP and Soft Contact Lenses are valuable and useful medical options, and an eye care professional should be contacted for further information about the pros and cons of each lens type.
