Most people opt for the convenience of the lens.In addition, unlike glasses, they allow the person to look natural.Contact lenses are used for so-called correction of refractive errors.This visual disturbances, which include nearsightedness (myopia), farsightedness (hyperopia), astigmatism and presbyopia.Lenses to correct astigmatism are called toric

.Usually they are made to order, subject to the disorder of each particular case.

Moreover, contact lenses can be used by people who were operated for cataract, when the "native" clouded lens is removed.Also, the lens used in the treatment of certain eye diseases such as keratoconus (thinning and changing shapes on the corneal cone), and traumatic or infective corneal damage.
