Characterized by a slight blurring of the vision or headaches or eyestrain, astigmatism is the most common vision problem. It is typically caused by an irregularity in the shape of the cornea; often the cornea will have an oblong or oval shape rather than the spherical shape of a healthy eye.
This condition can be hereditary, but the problem may worsen as part of the aging process. Additionally, astigmatism can be caused by a trauma that scars or otherwise alters the shape of the eye.
If you think you may have astigmatism, it is important to utilize the skills and experience of a reputable eye care professional. A simple, non-invasive eye examination will provide the information that is needed to correct the problem with prescription glasses or contact lenses.
