Although you may be more accustomed to soft contact lenses, a second, lesser-known type of contact lenses exists: rigid gas permeable (RGP) contact lenses, also known as oxygen permeable lenses.
In reality, RGP lenses are a newer technology than soft contacts, which are longer-lasting, allow better vision quality, and provide increased resilience. Further GP lenses can also be less expensive in the long run than soft lenses. Certainly, you need to first discuss with your optometrist to decide if GPs suit your lifestyle. Our optometry office can help you determine whether you’re a candidate for GP lenses.
Because an RGP is composed of inflexible material, it retains its form well when you blink, which can afford crisper vision than the average soft lens. Additionally RGPs are particularly long-lasting. Though they will crack if stepped on, they don’t easily rip like soft lenses. Also, since they consist of materials that don't include water, proteins and lipids from your tears won't stick to GPs as easily as they will to soft lenses. People that are extra particular about vision quality will most likely opt for GPs.
On the downside, GPs must be worn consistently in order to reach optimum comfort. Additionally, some people report “spectacle blur” with RGPs, which is when vision is unclear when the lenses are taken out even while wearing glasses. Although the effect is not permanent, it can necessitate full-time GP wear.
If you are considering GP lenses, make sure to first ask your eye care practitioner to verify if you definitely are a candidate. You never know…hard lenses might be the perfect match for you!
