If you have astigmatism – a common condition where the eye isn't perfectly round, but more football- or egg-shaped – then you'll need a special design of contact lenses called "toric" lenses for clear vision.
Toric contact lenses are available in both soft and rigid gas permeable (RGP or GP) lens materials. Most contact lens wearers who need toric contacts choose soft toric lenses.
How do toric lenses work?
When you have astigmatism, different meridians of your eye need different amounts of correction for nearsightedness or farsightedness. Imagine the front of your eye is like the face of a clock: A line drawn from the 12 to the 6 is one meridian, a line from the 1 to the 7 is another, and so on.
Soft toric contact lenses have different powers in different meridians of the lens to correct the eye's astigmatism. They also have design elements to keep the lens from rotating on your eye, so the meridians of the lens stay aligned with the meridians of your eye.
Today, you can choose from many brands and styles of soft toric lenses. So if Brand A doesn't fit properly or rotates too much, Brand B may perform better.
