Toric Contact Lenses: A Great Way To Correct Astigmatism

So many people with astigmatism think they can't wear contact lenses. But there's actually a special kind of contact lens made just to correct astigmatism. Generally, the cornea is round, but the cornea of an eye with astigmatism is more oval-shaped, sort of like a football. This changes how light hits the retina, and as a result, vision is blurred.

The lenses prescribed to correct astigmatism are known as toric contact lenses. Toric lenses are constructed differently from regular lenses. Consider them almost like the bifocals of contact lenses; they contain one power for your myopia or hyperopia and another for your astigmatism. They feature curvatures at different angles. Because of how they're made, these lenses must remain in place on your eye in order to correct your vision, unlike spherical contact lenses, which have no effect if they rotate on your eye when you blink. However, lenses for astigmatism are smartly designed with this in mind, and they are a little heavier at the bottom, which prevents them from moving around.

There are a number of scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. Toric lenses are also available as color contact lenses, and as multifocal lenses. Hard contact lenses, also called rigid gas permeable lenses, provide a firmer shape which allows them to stay put when you blink, but usually, they're a little less comfortable than soft lenses. Rest assured, there's a contact lens which is just right for you.

Because toric lenses are a little more complex, expect the fitting to take a little more time. Still, with advances in the field of optometry, individuals with astigmatism can take advantage of the benefits of contact lenses, with many options to choose from.
