Astigmatism refers to an abnormal, elliptical shaping of the front surface of the human eye, or cornea. As a matter of fact, Astigmatism occurs in nearly everybody, the only difference is the degree of asigmatism's symptom varies from person to person. For this kind of people, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy. As for your situation, the astigmatism hardly cure by itself, but there is a opportunity to be reversed if you try to wear RGP, which means Rigid Gas Permeable Contact Lens, for the sake of correcting defects of vision. Besides, a minor operation also helps.
