Glasses or contact lenses for astigmatism? How about laser correction?
Astigmatism, also known as non-astigmatism, is a visual defect affecting more than 30% of the world's population. The problem is related to the distortion of the eyeball - specifically, the cornea or lens. Patients experience it as image curvature, deterioration in sharpness and contrast sensitivity. The defect is treated conservatively with glasses or contact lenses. For several years there has also been the possibility of laser correction of astigmatism.
