GP 20 (1 Lentilla)
GP is a brand of gas permeable annual contact lenses manufactured by CooperVision.
Also called Rigid Permeable Gas (RGP), are used since the 70s, then have an innovative manufacturing technology.
It is important not to confuse these GP lenses with their predecessors, the hard lenses , these provided the patient with a very clear vision but they did not have the capacity to transmit oxygen to the cornea, causing serious problems of hypoxia, among many other complications.
The GP lenses of Coopervision , allow sufficient oxygenation of the cornea to maintain eye health. The cheap GP lenses can even exceed the oxygen levels they transmit to the cornea (DK / t) with respect to many soft silicone hydrogel lenses.
Its design is rigid and provide better vision than soft lenses but are more uncomfortable to wear, while hydrogel lenses are invaluable in the eye, practically from the first moment, with these GP lenses it takes a while to adapt the eye to carry that strange body. This is because the diameter is much smaller, rubbing with the eyelid continuously, necessary for the tear fluid to be made between the lens and the cornea. If the use of these lenses is not frequent, every time we put them on, we will notice them and we will have to adapt to wear them.
The adaptation of the patient is usually not simple, in fact, usually more than a couple of tests are needed to reach the final lens that meets their needs, maintaining eye health, a fundamental concept for the proper functioning of the eye.
These GP lenses are easy to adapt, due to their high quality edge geometry.
