People with keratoconus have a thinning of the cornea that causes a cone-shaped bulge. A hard, gas-permeable contact lens is most effective for people with this condition, because it stays fixed on the cornea. People with extremely distorted corneas may need a piggybacking technique, in which they wear two lenses on each eye. A soft lens sits right on top of the cornea, and a gas-permeable lens is placed on top of it.
Giant papillary conjunctivitis is an inflammatory condition in which the eyes secrete proteins. Soft contact lenses don't tend to work well for people with GPC, because proteins deposit on the lens of their eyes and cloud them over. Daily disposable daily contacts may work better, because the proteins don't have enough time to accumulate. Hard, gas-permeable lenses also can work because the proteins don't tend to stick to them.
We'll discuss how to get and take care of contact lenses in the next section.
