What are Toric Contact Lenses?

Toric contact lenses are a type of contact lens designed to correct astigmatism, a refractive error that causes blurred or distorted vision. Astigmatism occurs when the cornea or lens of the eye has an irregular shape, which prevents light from focusing properly on the retina.

Toric contact lenses have a unique shape that accommodates the irregular curvature of the cornea in astigmatic eyes. They are designed to remain stable on the eye, in order to ensure that the corrective power of the lens stays aligned with the astigmatic axis of the eye. This is achieved through various design features, such as a weighted bottom or a thicker section of the lens.

Toric contact lenses are available in both soft and rigid gas permeable materials. They may be prescribed for daily wear or extended wear, depending on the specific needs of the individual. It is important to have a proper fitting and prescription for toric contact lenses, as the correct alignment of the lens is crucial for effective correction of astigmatism.
