Rigid Gas Permeable “RGP” Contact Lenses

Rigid gas permeable (RGP) contact lenses are custom-made contact lenses often used to fit people with irregular corneas, such as those with keratoconus or corneal grafts. They are also frequently used for individuals with high prescriptions.

Benefits of RGP Contact Lenses

  1. Excellent Clarity and Optics: RGP lenses provide superior clarity of vision and exceptional optics, making them a first-line option for many contact lens wearers.

  2. Adaptation Period: While they require a period of adaptation that isn’t needed for soft contact lenses, the long-term benefits often outweigh the initial adjustment phase.

  3. Long-Term Corneal Health: RGP lenses offer excellent long-term corneal health, providing a stable and healthy option for vision correction.

  4. Durability and Handling: These lenses are durable and easier to handle than soft lenses, which can make them a practical choice for many users.

Advancements in RGP Lenses

Traditional hard contact lenses, made of PMMA, were not gas permeable. The advent of gas-permeable materials, which are continually improving, has eliminated issues that used to be caused by traditional hard contact lens materials. This advancement has significantly enhanced comfort and corneal health for RGP lens wearers. Lens designs and treatments have also advanced, meaning the customization options are very wide.

RGP lenses are particularly beneficial for:

  • Individuals with irregular corneas, such as those with keratoconus or corneal grafts.

  • People with high prescriptions

  • Anyone seeking excellent clarity of vision and long-term eye health.

To ensure the best experience with RGP contact lenses, follow these care and usage tips:

  • Adaptation Period: Allow time for your eyes to adapt to RGP lenses. This period varies by individual but is essential for long-term comfort.

  • Annual Eye Exams: Regular eye exams are crucial for maintaining eye health and ensuring your lenses continue to fit and function correctly.
