Rigid gas permeable contact lenses, often called RGP or GP lenses, keep their shape on the eye while allowing oxygen to pass through the material. They can provide precise vision in selected prescriptions and irregular corneal conditions, but they require individual fitting.
Who may benefit?
Selected prescriptions
RGP lenses may provide sharp optics for myopia, hyperopia or astigmatism when professionally fitted.
Irregular corneas
They are often considered for keratoconus and other irregular corneal shapes.
Specialist designs
Multifocal and other designs may be available depending on anatomy, prescription and daily needs.
Durable material
The lenses can last longer than many soft lenses, but only with correct handling and replacement when advised.
How does fitting work?
- Prescription, eye surface and tear film are assessed.
- Corneal measurements or topography guide the initial design.
- Trial lenses are evaluated for position, movement, comfort and vision.
- Follow-up visits confirm eye health and allow adjustments.
What should you expect during adaptation?
Initial lens awareness is common because the lens is smaller and firmer than a soft lens. Wearing time is usually increased according to the practitioner’s instructions. Persistent pain, redness, light sensitivity or reduced vision is not normal and requires prompt assessment.
Safe daily care
- Wash and dry hands before touching lenses.
- Use only the care system recommended for the specific RGP material.
- Clean, rinse, disinfect and store with fresh solution as instructed.
- Never top up old solution and avoid exposing lenses or the case to tap water.
- Do not sleep, swim or shower in the lenses unless specifically instructed for an approved design and schedule.
