How to Know If You Might Have Astigmatism

Astigmatism is a common refractive error that can affect both children and adults. Many people in Lebanon, MO experience blurry or distorted vision and assume it is simple nearsightedness, but astigmatism may be the underlying cause. Our optometrist near you can evaluate your symptoms, perform diagnostic testing, and recommend appropriate astigmatism treatment.

What Is Astigmatism?

Astigmatism occurs when the cornea or lens has an irregular curvature. Instead of being evenly rounded, the surface may be shaped unevenly. Light entering the eye does not focus properly on the retina, and vision becomes blurred at near and far distances. This condition can occur alone or along with nearsightedness or farsightedness. Some people are born with astigmatism, while others develop it over time.

Common Signs and Symptoms

Blurred or distorted vision is the most frequent symptom. Letters may appear shadowed, and straight lines can look wavy. Eye strain often develops after reading, driving, or using digital screens for long periods. Headaches may occur, especially at the end of the day. Children may squint, tilt their heads, or struggle with schoolwork. If these symptoms sound familiar, an eye exam with an optometrist near you is recommended.

How Astigmatism Is Diagnosed

A comprehensive eye exam is required to diagnose astigmatism accurately. Visual acuity testing measures how clearly you can see at various distances. A refraction test determines the exact prescription needed to correct refractive errors. Additional instruments may be used to measure the curvature of the cornea. During the examination, the internal health of the eye is evaluated. Other causes of vision changes are ruled out, and a precise diagnosis is made.

Astigmatism Treatment Options

Astigmatism treatment typically involves prescription eyeglasses or contact lenses. Cylindrical lenses are designed to correct the uneven curvature of the cornea. Toric contact lenses may be recommended if you prefer contacts. Refractive surgery is another option for some patients. The cornea is reshaped to improve how light focuses on the retina. Your optometrist near you will discuss whether you are a candidate and explain the potential benefits and risks.
