The Benefits of Rigid Contact Lenses


Although you may be more familiar with soft contact lenses, another less familiar brand of contact lenses exists: rigid gas permeable (RGP) lenses, also referred to oxygen permeable lenses.

In truth, GP lenses are a newer technology than soft lenses, which last longer, allow greater vision quality, and offer enhanced deposit resistance. Further RGP lenses can also be less expensive in the long run than soft lenses. Certainly, its advised to first consult with your eye care practitioner to determine if hard lenses suit your lifestyle. Our optometry practice can help you figure out if you’re a candidate for RGP lenses.

Since an RGP is constructed from stiff material, it maintains its form well when you blink, which tends to afford clearer vision than the typical soft lens. Additionally RGPs are particularly long-lasting. Although they will crack if stepped on, they don’t easily rip like soft lenses. Also, since they're composed of substances that don't contain water, proteins or lipids from your tears don’t stick to GPs as readily as they will to soft lenses. Those of you who are extra particular about vision quality will most likely opt for RGPs.

On the downside, RGPs must be worn regularly to achieve maximum comfort. Additionally, some people report “spectacle blur” with GPs, which is when vision is blurry when the lenses are taken out even while still wearing glasses. Although the effect is only temporary, it can necessitate constant GP wear.

If you're looking into hard lenses, be sure to first speak to your eye care practitioner to ascertain if you really are a candidate. You never know…hard lenses might be the right solution for you!
