As a matter of fact, astigmatism is quite normal for many people. Mostly of us have astigmatism more or less, the only difference is the seriousness of asigmatism's symptom varies from person to person. The essential reason is reinconsistency between the bending of lens surface and cornea. Generally speaking, an astigmatism can cure itself owing to the restorative function of cornea. Nevertheless, it do not work for a serious situation, after all, the restorative function is limited. At this point, it's better for the person to wear RGP, which means Rigid Gas Permeable Contact Lens, for the sake of correcting defects of vision. Besides, a minor operation also helps. Thanks for consulting.
