Regular contact lenses are hugely popular, but they don't meet everyone's needs. For some, having a lens sit directly on the cornea is uncomfortable. Others have corneas with irregular edges that interfere with light transmission through standard contacts. For these people and more, the solution is to switch to scleral lenses. Here is some information about this option from Christenson Vision Care of Hudson WI.
They are eye contacts that are big enough to let their edges rest on the sclera, or white part, of the eye. This allows them to rise over the corneas instead of resting on them. They are typically just enough larger to reach the sclera where they meet the irises of the eyes.
Often, these lenses are used to treat eye conditions that make regular contacts or eyeglasses unusable. One such condition is keratoconus, which causes the corneas to bulge out. Other people who need these lenses include those who have had their corneas replaced. A replacement cornea has irregular edges that result in multiple points of light trying to focus inside the eye. Scleral lenses bypass the problem by being large enough to vault over the entire cornea. Those who have had their eyes' lenses replaced may benefit from these lenses as well.
People with dry eye sometimes find that they cannot wear regular contact lenses, but do well with the scleral version. The latter allows tears to form on the cornea without disturbance, so discomfort is greatly minimized. Those who suffer from other conditions that interfere with tear production also benefit.
