The Benefits Of Gas Permeable Contact Lenses
The most common contact lenses are soft contact lenses. The other two are hard lenses, one older made of a material called PMMA and gas permeable contact lenses (GP). People tend to like the GP contact lenses more than the soft lenses because they come with more advantages.
Gas permeable contact lenses are also known as rigid gas permeable lenses (RGP) or oxygen permeable lenses. Opticians will refer to them as GP’s or RGP’s. The eyes need sufficient oxygen to filter through them to work optimally, and GP lenses provide that breath-ability that the soft lenses do not have.
GP lenses are smaller than the soft lenses and during blinking your eyelids will suffer from initial “lens awareness”. Gas permeable contact lenses need a short time period to adapt to the foreign object in the eyes. This is in contrast to soft lenses which can be easily worn straight-away.
Because GP contacts contain silicone, they need hardly any water to retain their form, preventing the moisture being drawn out from your eyes. Their smooth finish and the fact that they do not draw water mean that they attract fewer protein and mineral deposits from your tears. This is more comfortable for your eyes.
GPs are particularly durable. Although they are breakable, they do not tear as easily as soft lenses. They are easy to clean and disinfect and because they are so robust they go a very long way compared to soft lenses meaning you need to replace them less frequently. Add to this the fact that they are cheaper and you will be spending a lot less money in the long-run.
Gas permeable contact lenses provide optimal vision correction for many different conditions, such as astigmatism and presbyopia, because GPs are available in many bifocal and multifocal designs. Different bifocal designs suit different people, so being able to choose is a huge advantage. Opticians will make the lenses according to your eyes’ requirements.
Using the latest technology GP lenses can be made thinner, with larger diameters, and with smoother edges than previously. Opticians are also more likely to use sophisticated techniques to map eye topography, allowing the surface of the back of the lens to have an optimal fit with the cornea.
In time the GP contact lenses will get better and better. By using up-to-date technology and sophisticated techniques the quality will get better. Once your eyes have adapted to the gas permeable contact lenses (this small delay of around one week is the only real drawback) you will have a comfortable, cheaper, more durable, easier to clean, healthier, optimal vision for your eye complaints.
