Toric Power

A toric power lens is a lens with different optical power and focal length in two orientations perpendicular to each other. One of the lens surfaces is shaped like a “cap” from a torus, while the other one usually is spherical.

Toric contacts, like all contact lenses, need to be prescribed by your doctor, who can choose the lenses that are right for your vision, and fit them for your eyes. Talk to your eye doctor if you think you need contact lenses for astigmatism or other vision problems.
