Gas permeable contact lenses, also called 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.
At Eyesite we offer a range of gas permeable lenses, which you can order online or in your local Eyesite practice.
Pros of RGP Lenses
Gas permeable lenses were introduced back in the 1970s, but today they continue to provide a wide range of benefits:
- They are much tougher and durable than soft lenses and last longer
- They provide crisper focus as they hold their shape better
- RGP lenses do not contain water so they resist bacterial deposits and are generally more hygienic if maintained
- Gas permeable lenses are easier to handle. They will not fold or tear as easily as soft lenses
- They can be worn at night to reshape the cornea so you don’t have to use contacts or glasses during the day
- One pair can last up to 3 years
- Because RGP lenses last longer, they are also cheaper
Despite their many advantages, gas permeable contact lenses aren’t for everyone. Some people prefer soft contact lenses, whilst others opt for monthly ones. Whatever your preference, at Eyesite we can find you the best vision correction solution to suit your needs. Please make sure you talk to an optician before changing your contact lenses.
Cons of RGP lenses
If you are considering changing to gas permeable lenses, you may want to consider the following:
- Whilst soft lenses are instantly comfortable, gas permeable lenses take some getting used to
- As they are smaller in size than soft lenses, RGP lenses may be more likely to dislogde in the eye during sports or other activities
- Soft lenses can be disposed of daily which means less cleaning and care is needed
Contact Lens Advice
When it comes to choosing the right type of contact lenses for you, comfort and convenience are the key variables to bear in mind. Gas permeable lenses tend to be best suited to individuals who are willing to go through a period of adaptation to achieve the sharpest vision and comfort possible.
Always talk to your optician before deciding on contact lenses, as they will be able to offer advice depending on your eye health and lifestyle requirements. At Eyesite, we offer a specialist contact lens experience, which allows our patients to find out more about contact lenses and try different types.
