Rigid Gas Permeable, or RGP lenses, are firm oxygen-permeable contact lenses designed to provide crisp, stable vision. Unlike soft lenses, RGP lenses hold their shape on the eye, creating a smoother optical surface that can improve clarity for people with high prescriptions, astigmatism, or irregular corneas.
Although they may require a short adaptation period, RGP lenses are durable, breathable, and can offer excellent long-term visual performance when properly fitted and cared for.
RGP lenses sit on the tear layer over the cornea. Because the lens keeps its firm shape, it helps create a smooth focusing surface in front of the eye. This allows light to focus more accurately, resulting in clearer and more stable vision.
RGP lenses can help correct visual distortion caused by astigmatism or corneal irregularities, giving clearer vision than standard soft lenses in suitable cases.
Their oxygen-permeable material allows more oxygen to reach the cornea, helping to support healthier and more comfortable lens wear.
Because RGP lenses maintain their shape, they provide consistent optical correction and reduce the blur or fluctuation some wearers experience with soft lenses.
A detailed contact lens assessment is needed to determine whether RGP lenses are suitable for your eyes, prescription, corneal shape, and lifestyle.
RGP Lens Fitting & Assessment involves a series of comprehensive eye tests to evaluate your vision, examine the health of your eyes, and determine the most suitable lenses for your lifestyle. These tests ensure a precise, comfortable fit and personalised care tailored to your individual visual needs.
Clinical measure of the eye's ability to resolve fine detail at a standardized distance. It quantifies the clarity or sharpness of central vision, which is essential for tasks such as reading, driving, and facial recognition.
This is a standard eye examination used to determine your refractive error and provide the correct prescription before issuing new glasses.
Diagnostic evaluation to determine the presence, type, and severity of Dry Eye Disease (DED). Dry eye occurs when the eyes do not produce enough tears or when the tear film is unstable, leading to discomfort, visual disturbances, and potential ocular surface damage.
Detailed examination of the front part of the eye, including the cornea, lens, and surrounding structures. Using advanced equipment, this assessment helps detect early signs of eye disease, monitor contact lens safety, and ensure your eyes remain healthy and comfortable.
Measurement of the anterior curvature of the cornea, particularly the central 3 mm zone, to determine the corneal refractive power and astigmatism.
Our optometrist will assess how well the lenses fit on your eyes, checking their movement, stability, and comfort. This ensures you enjoy clear vision while keeping your eyes healthy. There will be different fitting processes that are tailored for different types of specialty lenses.
You’ll be guided through proper techniques for inserting and removing your lenses safely. This hands-on training helps you build confidence and comfort in handling your lenses.
We’ll explain the best practices for cleaning, storing, and replacing your lenses on schedule. Following these steps helps prevent infections and keeps your eyes comfortable for daily wear.
