Astigmatism causes blurry vision that an eye doctor can correct with the proper eyeglass prescription. During an examination, the doctor will have the patient look through a phoropter, a flat machine that sits against the patie...
In people with the eye disorder astigmatism, the light coming into the eye becomes focused in two places instead of being pinpointed down to a single spot at the back of the eye. This can induce blurry vision, headaches and eye...
Amblyopia and Astigmatism are two different eye conditions that can occur separately or concurrently, with Astigmatism leading to amblyopia. Astigmatism describes a condition in which the cornea, the clear dome-shaped covering ...
astigmatism, which is an irregular curve of the cornea, is so common that more people have it than don't have it. The University of Michigan's Kellogg Eye Center notes that astigmatism is not a disease, but rather a visual dist...
Toric contact lenses correct a common eye condition called astigmatism. The American Optometric Association describes astigmatism as a vision problem caused either by an irregular shaped cornea, which is the clear outer layer o...
Astigmatism occurs when parts of the eye (cornea, lens or the clear cover in the front of the eye) are abnormally curved, causing light to focus improperly on the retina (the part of the eye that converts images and light into ...
astigmatism is a common vision problem. The cause of an astigmatism is a cornea or lens that is irregular in shape--usually the cornea. An astigmatism may be accompanied by near-sightedness or far-sightedness. You may not even ...
Astigmatism is a defect in the cornea (substance covering the eye) that can lead to blurry vision.
Astigmatism is a condition in which the cornea is irregularly shaped and therefore unable to properly focus light rays, creating vision that is slightly blurry, even when corrected with typical glasses or contacts. Patients may...
Astigmatism is a very common visual disorder created by abnormal or irregular curvature of the cornea, which causes light to bend irregularly as it passes through the lens of the eye, generating distortions in the formation of ...

The term "astigmatism" refers to an abnormal shape of the cornea of the eye. Normally, the cornea is smooth and round, thus enabling it to bend incoming light in a fashion that focuses it on a very exact point at the back of th...
In order to understand what astigmatism is, and more specifically regular (versus irregular) astigmatism, let’s first get a basic understanding of what astigmatism is in general. The normal human eye has several structu...
Astigmatism is a treatable eye condition that results in blurred vision. It occurs when the front of your eye, which is also called the cornea, or the lens develops a different curvature in one direction. Typically, the cornea ...

When astigmatic patients visit their ophthalmologists for treatment, they're often prescribed corrective lenses to manage their vision problems. Contact lenses have flourished over the past 25 years. While most contacts are sa...
Your eye doctor can determine an ideal prescription strength to correct your astigmatism. You'll likely need to take an array of tests, including a slit lamp examination and a visual acuity test. Your optometrist will also pla...
The reason most people in the past with a severe astigmatism could not wear contacts is the shape of their cornea. The cornea of someone who has an astigmatism is shaped more like a football, or oval shaped, whereas the cornea...
Astigmatism results when your cornea or the lens inside your eye is irregularly shaped. When the curvature of the lens or the cornea is uneven, light cannot focus properly on the retina, causing blurred vision. This eye conditi...
