Toric contact lenses are uniquely designed to correct astigmatism, offering a custom fit for each patient’s eye. Unlike standard contact lenses with a spherical surface, toric lenses have an oblong shape tailored to accommodate the irregular shape of the astigmatic eye. They can be crafted from either soft or rigid gas permeable (RGP or GP) lens materials, with soft toric lenses being more common.
Toric lenses are engineered to stay in place on the eye, ensuring proper vision. Soft toric lenses may experience rotation with eye movement or blinking, and in such cases, rigid gas permeable lenses could be a more effective alternative. While RGP lenses may have a longer adjustment period initially, they often match the comfort of soft lenses once adapted, and they are generally easier to care for.
