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. While years ago it was believed that contact lenses were unable to correct astigmatism, there are now toric contact lenses available to do the job.
