Toric contact lenses are an often prescribed treatment for astigmatism. They are available in different designs depending on their intended use. Toric contact lenses can be found either with rigid gas permeable (rgp) or soft designs. They are available as daily disposable or extended wear options.
Unlike spherical lenses, Toric Lenses are built with two different power levels - one for hyperopia or myopia and another for astigmatism. As a result of this it is important that the lens remain in the same position once inserted. Contact lens manufacturers achieve this with the use of a ballast design that centralizes the lens during blinks or eye motion. This preserves the visual quality of the lens.
