Problems With Astigmatism & Lenses

The American Optometric Association reports that astigmatism, an irregular shape of the cornea, is extremely common. In fact, most people have some degree of astigmatism. Because a curved cornea won't let light focus correctly on the eye's retina, a person with astigmatism has slightly blurry vision at any distance. Contact lenses and eyeglasses are among the treatments used to treat the common vision condition astigmatism.

Myth about Astigmatism and Contact Lenses

• Many people with astigmatism erroneously believe (or have been told by an eye care professional) that they can't wear contact lenses. However, astigmatism can be corrected with contact lenses, even soft contacts that come in disposable, multifocal and colored varieties.

Toric Soft Contact Lenses

• Toric soft contact lenses are often used to address problems with astigmatism. These contact lenses correct the corneal curvature associated with astigmatism and hold their shape better on the surface of the eye. This helps the person with astigmatism see more clearly. The only problem with these types of contacts is that they may be more expensive than traditional or disposable soft contact lenses and require more fittings by an eye care practitioner.

Rigid Gas-Permeable Lenses

• Sometimes people with astigmatism choose rigid gas-permeable lenses that do not bend and flex like soft contacts. Because they keep their shape on the eye's cornea, a person with astigmatism may find they're able to see better. These types of contacts may be used for a year or more, so a person who's likely to lose or damage them might not be the best candidate for rigid gas permeable lenses.

Eyeglasses

• Glasses are often used to help people with astigmatism see better. However, because they do not sit on the surface of the eye, contact lenses for astigmatism may offer a wider field of vision and crisper eyesight.

Check with an Eye Care Professional

• Optometrists and ophthalmologists will check for astigmatism in a person's vision as part of routine eye examinations. The American Optometric Association notes that all questions about astigmatism and the best way to correct it and any problems with astigmatism and lenses should be directed to an eye care professional.
