Symptoms of eye astigmatism include headaches, eyestrain, and blurred or distorted vision. When these symptoms begin to interfere with daily activities, Mayo Clinic recommends seeing an eye doctor. During the exam, the doctor determines if the patient has astigmatism, the degree of the condition and options for correction.
Astigmatism is an irregular shape of the lens of the eye, according to Mayo Clinic. The normal cornea is smooth and even in all directions. An irregular shape causes blurred vision at all distances. Astigmatism sometimes accompanies vision problems, such as nearsightedness or farsightedness. If the condition is severe enough to cause vision problems, doctors often treat it with corrective lenses or surgery.
