The most common form of vision problems is refractive errors where your eyes don’t properly focus light, leading to blurry vision. One type of refractive error is astigmatism, or when your eye’s cornea or lens has an irregular curve. At Eyes on Hayden in Scottsdale, Arizona, the team of expert optometrists diagnose astigmatism and treat it with prescription eyeglasses or contact lenses, and can provide referrals to permanently correct it with laser eye surgery if needed. Schedule an appointment online or over the phone today for an eye exam or consultation.
Astigmatism is a refractive error, like being nearsighted (myopic) or farsighted (hyperopic). A refractive error means your eye has difficulty focusing light because of the eye’s shape and your uncorrected vision is blurry as a result. It’s not a disease and it doesn’t mean anything is wrong with your eye health. It does mean, however, that you probably need glasses or contact lenses.
Astigmatic eyes have an irregular shape, so they bend light unevenly, producing blurry, wavy, or distorted images. Eyes without astigmatism are smooth and even, bending light evenly in all directions to produce a clear image.
Eyes are almost never perfectly round, so nearly everyone has at least some astigmatism. Astigmatism only requires corrective treatment if it’s significant enough that you have a hard time seeing. In addition to blurry vision, astigmatism may cause headaches, frequent squinting, and difficulty driving at night.
Astigmatism is genetic, and you’re usually born with it. Children are usually diagnosed with astigmatism after they start school and have a hard time reading or concentrating. In fact, it’s fairly common for children to be misdiagnosed with learning or behavioral disorders when they just need glasses.
Astigmatism usually gets worse as children get older and their eyes continue to grow and develop. Astigmatism usually stabilizes around age 20. Astigmatism may also develop later in life because of an eye injury, eye surgery, or disease such as diabetes.
Part of every eye exam at Eyes on Hayden is testing your eyes for refractive errors. Your optometrist can determine if you have astigmatism and pinpoint your corrective lens prescription.
Many people with astigmatism simply wear eyeglasses or contact lenses so they can see clearly. Adults can undergo laser eye surgery, also known as LASIK, to reshape their corneas and correct their astigmatism. Most people no longer need glasses or contact lenses after undergoing LASIK.
An ophthalmologist performs laser eye surgery, and it’s a safe, quick, effective procedure. Your optometrist at Eyes on Hayden can provide a referral if you’re interested.
