Rigid lens designs that have spherical front and back surfaces neutralize astigmatism by compensating for the irregular shape of your askew cornea or lens. These round lenses can remedy mild to moderate astigmatism, but high levels of astigmatism need a specialized toric style.

Toric lenses have upright and straight axes that allow for varying corrective powers. Research has shown that a maximized prism balance layout, such as the Biofinity toric lens, uses the lowest rotation as well as fastest reorientation after blinking.
