If you've answered yes to any, or all, of the above questions, your vision maybe compromised by astigmatism. One of the most common optical, almost everyone suffers from some form of astigmatism.
What it is...The eyeball is, by nature, spherical in shape. An eyeball with astigmatism is shaped like a rugby ball or the back of a spoon. As a result, when light from an object enters the eye, it is refracted more in one direcion than another, making only part of the object appear in focus. Objects at any distance can also appear blurry and wavy.
What causes it...The exact scientific cause is unknown, but specialists believe it may be an inherited condition or a natural progression with age.
How it's diagnosed...An eye exam performed by a doctor will diagnose astigmatism.
How it's treated...Almost all degrees of astigmatism can be corrected by prescrption eyeglasses or contact lenses.
