If you have astigmatism, you may need special soft contact lenses called toric lenses to help you see better. These lenses are custom designed to fit your unique-shaped eye and provide clear vision throughout the day. Toric lenses do not come without their challenges and this fact makes it even more important to have these lenses fit by an experienced professional like the eye doctors at Toronto Eye Care.
What are toric lenses?
In order to understand what makes toric lenses different, it’s important to first understand what astigmatism is and how it affects the eye. Astigmatism is not an eye disease, but is one of the refractive errors of the eye preventing light rays from bending correctly for proper focus. It’s caused by a deviation, usually in the cornea, from the typical spherical shape that the cornea normally takes; instead of being symmetrically round, the cornea is more cone or football-shaped. Many people with the condition may simply assume that their blurred or distorted vision is just part of their near-sighted or far-sighted prescription but astigmatism is actually another error which compounds their visual dysfunction.
A toric contact lens is a custom designed and shaped to conform to the eye and correct the astigmatism. Its unique shape creates different light-refracting powers on the vertical and horizontal planes of the lens to accommodate the differently-shaped cornea of patients with astigmatism, and thus properly correct the person’s vision. Simply increasing the power of your regular contact lens to correct the astigmatism is generally ineffective and a potential source of even greater eye strain.
