Focusing on Astigmatism and Contact Lenses

Many people with astigmatism think they can't wear contact lenses. But there's actually a special sort of contact lens made just to correct astigmatism. Generally, the cornea is round, but the cornea of an eye with astigmatism is more elliptical. This ostensibly small detail actually changes the way light hits the retina, and results in blurred vision.

Toric contact lenses are prescribed to correct astigmatism. What differs between toric lenses and regular lenses is the design. Normal lenses have one power, but toric lenses have two: one for distance vision and one for astigmatism. They have curvatures at various angles. Because of their unique design, toric lenses need to stay in place on your eye in order to correct your vision, unlike spherical contact lenses, where lens movement caused by blinking has no effect on your vision. A great feature of toric lenses is the fact that they're weighted at the bottom, which helps them stay put when you blink or rub your eyes.

There are multiple scheduling options for toric contact lens wearers, including soft disposable contact lenses, daily disposable lenses, and frequent replacement lenses. And those with astigmatism need not worry about options; toric lenses even come in color, or as multifocals. Rigid gas permeable lenses (RGP, or hard contact lenses) are made from a tougher material that remains in form even when you rub your eyes or blink, and might provide better vision than other lenses. But they are often not as comfortable. Rest assured, there's a contact lens which perfectly suits your unique needs, and your eye care professional will find it for you.

Due to the fact that toric lenses are a little more complex, expect the fitting to take a little more time. But it's worth it. With advances in the field of optometry, those with astigmatism have lots of life-improving options to choose from.
