Rigid gas permeable or RGP lenses, are made of a firmer material than their soft contact counterparts. RGP lenses have the ability to let oxygen reach the eye behind the lens, which is essential for good eye health. Despite their name, ‘rigid’ gas permeable contact lenses are actually quite flexible, which ensures a comfortable and eye-friendly experience.
Unlike soft lenses they are a lot more durable and can be worn for longer periods of time, often they are worn daily and replaced every six to twelve months.
Rigid gas permeable lenses are perfect for the following people:
- Those who have an astigmatism as they offer a more rigid fitted lens
- People with eye conditions that cause irregularity to the shape
- Soft lens wearers who don’t find their vision is sharp enough
