What Is Astigmatism? A Simple Explanation for Curious Eyes

If you are visiting Greenwich Eye Care in Old Greenwich, CT, you may hear the term astigmatism during your eye exam. Astigmatism is a common vision condition that affects how light enters the eye. Understanding it can help you recognize symptoms, know your treatment options, and maintain clearer vision.

Understanding Astigmatism

Astigmatism occurs when the cornea or lens of the eye has an irregular shape. Instead of being perfectly round, the surface curves more in one direction than the other. This uneven curvature prevents light from focusing properly on the retina. As a result, images may appear blurry, distorted, or stretched. Some people experience astigmatism alongside nearsightedness or farsightedness.

Symptoms to Watch For

People with astigmatism may notice blurred vision at all distances. Eye strain, headaches, or frequent squinting are also common signs. Sometimes, objects may look tilted or stretched. Symptoms can appear gradually, so you might not notice them immediately. Children with astigmatism may struggle to read or have trouble seeing the board in school. Regular eye exams can detect these changes early.

Diagnosis and Testing

Our optometrists diagnose astigmatism through a comprehensive eye exam. We may use a keratometer to measure the curvature of the cornea or a phoropter to check how your eyes focus. These tests help determine the severity and type of astigmatism. Once diagnosed, we can discuss treatment options that best suit your needs.

Treatment Options

Astigmatism is often corrected with prescription glasses or contact lenses. Some people choose toric lenses specifically designed to address irregular corneal shapes. For those seeking a more permanent solution, refractive surgery may reshape the cornea. Our eye doctors will guide you to the most effective solution for your lifestyle.
