Astigmatism is a problem of the eye caused by a defect in the spherical curvature of the eye leading to bluured vision. This condition leads to an eyes inability to focus light, since images are not formed on one point. This leads to blurred vision. It is caused when the eye's curvature (the cornea specifically) is not spherical but rather irregular.
