Astigmatism

Astigmatism is a naturally occurring, treatable condition of the eye that causes blurred or distorted vision. Astigmatism is very common; most people have it to some degree. Slight astigmatisms do not affect vision or require treatment, but more serious cases can cause eye discomfort and headaches. In astigmatism cases, the shape of the eye is not completely round, so when light hits the back of the eye it is refracted more in one direction than the other. This allows only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy, making it difficult to see fine details.

Astigmatism often is present at birth and it frequently occurs in combination with nearsightedness or farsightedness. Sometimes it sets in after certain types of eye surgery, such as cataract removal. Normally astigmatism can be corrected using glasses, contact lenses, or laser eye surgery. The condition can change over time, requiring updates to corrective lens prescriptions. In children, if left untreated, astigmatism in one eye can cause amblyopia, more commonly referred to as "lazy eye." It is possible to have astigmatism and not know it, especially in children who may not recognize the symptoms. This underscores the importance of comprehensive eye exams annually.
