Astigmatism occurs when the front surface of your eye (cornea) or the lens, inside your eye, has a slightly different surface curvature in one direction from the other.

Astigmatism
Definition
Astigmatism is the result of an inability of the cornea to properly focus an image onto the retina. The result is a blurred image.

Astigmatism
Definition:
Astigmatism is a condition in which the cornea of the eye is asymmetrically curved, causing out-of-focus vision.

Astigmatism is very common and is usually present from birth. Most people have a slight astigmatism - it's rare for the cornea to have developed in a perfectly symmetrical way. But in mild cases, the eye can adjust to focus the light adequately.

astigmatism - Astigmatism is a condition in which an abnormal curvature of the cornea can cause two focal points to fall in two different locations making objects up close and at a distance appear blurry.

Astigmatism is best described as distorted or warped vision due to the surface of the eye being somewhat irregular in shape. Here, the eye has various focal points causing images to be distorted.

Soft contact lenses are used to correct farsightedness, nearsightedness, and some kinds of astigmatism (uneven curving of the cornea, which is the clear outer layer on the front of the eye).

Most people find that their vision improves significantly following a corneal transplant, although many people have a degree of astigmatism, an uneven contour of the cornea that can cause some vision problems such as blurriness.
