Astigmatism is a common refractive condition that occurs when the cornea or lens has an irregular curvature. This uneven shape affects how light enters the eye and can lead to blurred or distorted vision. Understanding astigmatism empowers patients to recognize symptoms, seek timely care, and explore effective treatment options. Eyes On Norbeck is committed to helping patients stay informed about the causes, signs, and solutions for astigmatism so they can enjoy clearer, more comfortable vision.
Understanding Astigmatism and Its Impact on Vision
In a healthy eye, the cornea and lens have a smooth, round curvature that allows light to focus sharply on the retina. With astigmatism, the surface is more oval or football shaped, which causes light to focus at multiple points instead of one. This leads to distorted vision at various distances and can make everyday tasks more challenging.
Symptoms and Diagnosis
Astigmatism often produces symptoms such as blurred or fuzzy vision, eye strain, headaches, and difficulty seeing clearly at night. Because these signs can develop gradually, many people do not realize they have astigmatism until it begins to interfere with daily activities.
Diagnosis requires a comprehensive eye exam, which may include visual acuity testing, keratometry to measure the curvature of the cornea, and corneal topography for detailed mapping. These evaluations help determine the degree and type of astigmatism present.
Causes and Genetics of Astigmatism
Astigmatism can be inherited, meaning its root cause often lies in the natural shape of the eye passed down through family genetics. It may also develop due to changes in eyelid pressure or as a result of certain eye conditions. For example, keratoconus, a condition that causes the cornea to become thinner and more cone shaped, can significantly worsen astigmatism over time.
Treatment Options, From Glasses to Surgery
There are several effective options for correcting astigmatism, depending on individual vision needs and preferences.
Eyeglasses are the most common solution, providing clear and comfortable vision by adjusting how light enters the eye. Toric contact lenses are another reliable option that offers more precise correction for corneal irregularities.
For individuals seeking a long-term correction, refractive surgeries such as LASIK or PRK can reshape the cornea to create a more uniform curvature. These procedures can significantly reduce or eliminate the need for corrective lenses.
The Role of Eye Care Providers
Regular eye exams are essential for detecting astigmatism early and maintaining overall visual health. Eye care providers can monitor changes in the cornea, guide patients on the most effective treatments, and ensure that any vision correction method remains accurate and comfortable.
