Because they are made to order, there is an initial cost investment and they will take up to a week to manufacture if you do need a replacement pair. Costīecause they last so long, GPs are much more cost-effective than soft lenses, especially disposable lenses that require a constant supply. Further, they do not dehydrate, which is often a cause for reduced vision with other lenses. Better Visionĭue to the rigid material, GPs have a smooth surface and maintain their shape, moving along with the eye to hold their place. While this may take some time getting used to initially, ultimately many find that they are just as if not more comfortable than soft contacts. GP lenses have a smaller diameter than soft contacts, meaning that they cover less of the surface of your eye. Their ability to transmit oxygen reduces eye problems such as dry eyes caused by reduced oxygen that are common in many brands of soft lenses or hard (non-GP) lenses. GP contact lenses are custom made for each patient based on the eye’s individual curvature, size, corneal shape. Further GPs last longer than soft lenses – when cared for properly, a pair can last a year or more. RGPs maintain their firm shape and will not dehydrate. Further protein deposits won’t build up on the lens, keeping them cleaner and healthier.īecause they are made with a strong durable material, GP lenses won’t tear and are easy to clean and disinfect. Unlike soft lenses, GPs don’t contain water which makes them less likely to attract and breed bacteria that can cause eye infections. Benefits of GP or RGP Contact Lensesīecause of the strong material and the ability to diffuse oxygen, GP lenses offer a number of advantages over soft contact lenses. This increases comfort, health and safety during contact lens wear. GP contacts are made of a firm plastic material which allows the passage of oxygen through the lens to your cornea and the front surface of your eye – essentially allowing your eye to “breathe”. GP lenses are currently less popular than soft lenses but offer a number of advantages and are continuing to improve as research and technology advance. Gas Permeable (GP) or Rigid Gas Permeable (RGP) contact lenses are an alternative to soft contact lenses that are made from a hard, oxygen permeable material.
