Determine if Rigid Gas Permeables are the right contact lense for you

Rigid Gas Permeables also known as RPG contact lenses are the latest and most advanced hard contact lenses. Invented in 1985, when soft lenses were already 15 years old, Rigid Gas Permeables turned out to be a long awaited solution for people who, for different reasons did not cope well with the old lenses.

The old hard contacts were made of 'polymethyl methacrylate' and did not allow any oxygen to flow through. Rigid gas permeables on the other hand are made from modern polymers and contain silicon, which permits oxygen flow and make them more flexible than the old hard contact lense. And as you may know your eyes need a lot of oxygen.

Advantages of Rigid Gas Permeables

• Excellent for people who are very critical about the crispness of their vision. Your visibility with RGP's is very constant.

• Rigid gas permeables can be polished if needed.

• There is no buildup of natural deposits from your tears onto the RGP unlike soft contact lenses.

• Rigid gas permeables are stronger than any other contact lense; they might last for years.

• The shape of the contact lens does not change when you blink. Some people experience a temporary blurring when blinking with soft contact lenses.

Disadvantages of Rigid Gas Permeables

• You need to wear Rigid Gas Permeables on a regular basis in order to have a continous comfortable wear. They need some more time getting used to than the soft contact lense.

• Alternating Rigid Gas Permeables with regular glasses is difficult because it will take some time before your eyes are re-adjusted.

• RGP lenses need some care on your part. They need some light rubbing with a solution. Your optometrist or RGP manufacturer will recommend a cleaning system for you. (Rigid Gas Permeables do exist as 1-month night and day contacts; these need far less care).

Types of Rigid Gas Permeables

• Monthly Rigid Gas Permeables

• 1 Month night and day contacts

• disposable RGP's

Most RGP's nowadays are visibility tinted in case you need to find them again after dropping or when your contact lense is lost in your cleaning solution for example.
