Although you may be more accustomed to soft contact lenses, another less familiar kind of contact lens materials exists: rigid gas permeable (RGP) lenses, also referred to oxygen permeable lenses.
In reality, GP lenses are a newer technology than soft lenses, which are longer-lasting, are often more successful in improving vision, and offer improved durability and resistance to protein deposits. Additionally RGP lenses can also be less expensive in the long term than soft lenses. Certainly, its advised to first consult with an eye care practitioner to decide whether GPs suit your lifestyle. Our optometry office can help you determine if you’re a candidate for hard lenses.
Because a GP is composed of inflexible material, it retains its form well when you blink, which can afford sharper vision than the typical soft lens. In addition RGPs are extremely long-lasting. Though they will break if stepped on, they don’t tear easily like soft lenses. Further, since they're composed of substances that don't include water, proteins or lipids from your tears won't adhere to RGPs as easily as they do to soft lenses. People that are especially fussy about quality of vision will most likely opt for RGPs.
One of the inconveniences of hard lenses is that they need to be worn regularly in order to achieve optimum comfort. Further, there are some who report “spectacle blur” with RGPs, which is when eyesight is blurry when contact lenses are taken out even while wearing glasses. Although the effect is only temporary, it can demand full-time GP wear.
If you are thinking about hard lenses, make sure to first speak to your eye doctor to verify if you really are a suitable candidate. Who knows…hard lenses might be the perfect answer for you!
