Gas Permeable Contact Lenses– The rigid contact lens which is hard to the touch and an alternative* to spectacles – for full time use. These lenses are suited to both long and short sighted patients and those with astigmatism; they are also available in multifocal form. These lenses allow good oxygen flow to the cornea for constant use over many years but can be more difficult to adapt to initially. Due to the rigid nature of the material the patient will be much more aware of the contact lens until they have built up a wearing time tolerance to the lens.
These lenses are not replaced as frequently as soft lenses but regular replacement should be maintained.
Annual replacement is our recommendation.
