The refraction deviation is a lack where the eyes cannot focus the shadow that falls for the retina so as the shadow that is received very vague or the design. To the normal eyes, explain from Tri, the functioning eyes reflect or catch the rays that are continued exact in line with the retina. If being gotten by the refraction deviation, the object shadow that is seen by him will not fall exact the retina, but behind or in front of the retina. Therefore, the refraction deviation must be corrected by the optic system so that the rays that earlier were not caught in a manner the focus to the retina becomes exact on the retina. One of them is with the spectacles or contact lenses.

To repeat the refraction deviation, from Tri recommend to only do not carry out the improvement medically, but also in a kosmetis manner. So that become the reason of the contact lenses creation during the 1800 ’s. for people who have the refraction deviation, both that is backward and plus, that is very high, usually by using the spectacles, their eyes will be seen become smaller or grow because his glasses are thick.

Owing to the progress of technology and the discovery hidrogel, the scientists succeed in finding the more comfortable contact lenses material is used with the power deliver moderate oxygen. Soft the lens or the soft lens can deliver oxygen through the content of his water. This superiority make soft the lens is often chosen apart from the ease to be received in pasaran,says the specialist doctor who opens the practice in Jakarta Eye Center, Street Cik Ditiro No 46, Menteng, Jakarta this Centre. For the medical interests, according to from Tri, many ophthalmologists who recommend the use of contact lenses Rigid Permeable Gas or RGP. A newest contact lenses technology that are made from silicon akrilat. Be different from soft the lens, RGP more hard and stiff. However, in accordance with his name, the RGP capacity to deliver gas especially oxygen is better compared with soft the lens. This that can minimise the occurrence of the reaction of the negative resulting from the use of contact lenses in a period of that is long.
