Eye astigmatism has abnormally curved cornea or lens prevents light from focusing properly on the retina. Thus, vision becomes blurring at any distance.
Astigmatism is a very common vision condition. Most people have some degree of astigmatism. Slight amounts of astigmatism usually do not affect vision and do not require correction or treatment. However, larger amounts cause distorted or blurred vision, eye discomfort, and headaches.
Astigmatism commonly occurs with other vision conditions like myopia nearsightedness and hyperopic farsightedness. Together these vision conditions are considering as refractive errors because they affect how the eyes refract light.
