Astigmatism is a common refractive error that affects how light focuses on the retina. Many people experience blurred or distorted vision without realizing that astigmatism may be the cause. Our optometrist can diagnose this condition during a comprehensive eye examination and recommend appropriate astigmatism treatment.
What Is Astigmatism?
Astigmatism occurs when the cornea or lens has an irregular curvature. Instead of being perfectly round, the surface of the eye is curved, which causes light entering the eye to not focus evenly on the retina, and vision can appear blurry at all distances. Astigmatism may be present at birth, or it can develop over time. Some individuals are told that astigmatism is mild and does not require immediate correction. Others need prescription lenses to improve clarity.
Common Symptoms of Astigmatism
Blurred vision is one of the most frequent symptoms. Objects may appear stretched or shadowed, and fine details can be difficult to see. Headaches and eye strain are also common, especially after reading or using digital screens for long periods. Night driving may become challenging, since lights can appear streaked or haloed. Children with astigmatism may squint, tilt their heads, or complain of difficulty seeing the board at school. Adults may notice that their current glasses no longer provide clear vision.
How Is Astigmatism Diagnosed?
An optometrist uses several tests to diagnose astigmatism. Visual acuity testing measures how clearly you can see letters at different distances. A refraction assessment determines the exact prescription needed to correct refractive errors. Keratometry or corneal topography may be performed to measure the curvature of the cornea. Other conditions that affect vision can be ruled out, and a clear diagnosis can be made.
Astigmatism Treatment Options
Eyeglasses are a common and effective treatment. Special cylindrical lenses are prescribed to correct the uneven curvature. Contact lenses can also be used, including toric lenses that are designed specifically for astigmatism.
In some cases, refractive surgery may be discussed. Your optometrist will explain the benefits and risks of each option, and recommendations will be based on your vision needs and lifestyle.
