Rigid & Disposable Contact Lenses

Gas permeable contact lenses are rigid lenses made of durable plastics that allow oxygen to pass through the lens. These lenses also are called GP lenses, rigid gas permeable lenses, RGP lenses and oxygen permeable lenses.

These have the advantage of being easy to wear, providing good comfort without a long period of adaptation. Older hydrogel materials (a mixture of water and plastic polymers) are now being superseded by silicone hydrogel materials, a development introducing silicone into the plastic matrix. These provide up to five times the oxygen permeability of the older lens materials allowing the eye to breathe more easily and promote better eye health while wearing lenses

Two-weekly disposable contact lenses can be worn daily for up to two weeks at a time. They must be removed at night and cleaned and stored with the solutions recommended to you by your optician. These two-weekly disposable lenses in some cases may offer better value since you purchase fewer lenses.



They are typically made from a material called silicone hydrogel which allows much more oxygen through the lens compared to standard contact lenses, which is good for your eye health and aids comfort.

Among the many advantages of wearing monthly disposable lenses are:

• You only need 12 pairs of contact lenses for the whole year.
• Option of silicone hydrogel material which allows much more oxygen through the lens compared to standard contact lenses. This is good for your eye health and aids comfort.
• Monthly disposable contact lenses can be worn daily for up to a month. They must be removed before going to bed each night, then cleaned and stored with the solutions recommended to you by your optician.
• They come in different types including monthly toric (corrects astigmatism), monthly multifocal (allows you to see distance and near), and monthly coloured (enhance or change the colour of your eyes).
