A Closer Look at Astigmatism and Contact Lenses

If you are someone with astigmatism and you think you can’t wear contacts, you’re mistaken. Contact lenses can actually be a way to correct the condition. A regular cornea is round, but the cornea of an eye with astigmatism is more elliptical. This changes how light hits the retina, and results in blurred vision.

The lenses prescribed to correct astigmatism are called toric contact lenses. Toric lenses are constructed differently from regular lenses. Regular lenses have just one power, but toric lenses have two: one for distance vision and one for astigmatism. Because they feature two different powers, toric lenses need to stay in place on your eye in order to correct your vision, as opposed to spherical contact lenses, which have no effect if they rotate on your eye when you blink. However, lenses for astigmatism are cleverly designed with this in mind, and they are weighted slightly at the bottom, which helps them stay in place.

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. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher substance that remains in shape even when you blink, and might provide even sharper vision than soft lenses. But the disadvantage is that they are often not as comfortable to wear. Together, we’ll be able to find the best brand to suit your eyes.

Fittings for toric lenses can sometimes require more time than the regular lens fittings you might be used to, due to the fact that these lenses are a little more complex. This all might sound a little daunting, but it’s worth the end result; effective treatment. Being fitted with the right product will only improve your vision, and consequently, your quality of life.
