Astigmatism is a refractive error, which distorts vision at both distance and near. The corneal surface is spherical, shaped (similar to a ball). When the shape of the cornea is sphere-cylindrical (like a football) it is known as astigmatism. This causes the light rays to reflect unevenly inside the eye. While some light rays focus on the retina, other light rays focus in front of, or behind the retina resulting in blurred vision. Patients with astigmatism may wear glasses or contact lenses, which provide more power to the other section. Contact lenses required to correct the astigmatism are termed toric lenses, the fit of these is more complex. If you are experiencing blurred vision, make an appointment today.
