Astigmatism

---

Astigmatism is a common refractive error that affects the way light enters the eye, causing blurred or distorted vision at all distances. It occurs when the cornea or lens of the eye is irregularly shaped, preventing light from focusing correctly on the retina. This condition can be hereditary or develop over time due to factors such as eye trauma, scarring, or eye surgery. Symptoms of astigmatism include blurry or distorted vision, eye strain, headaches, and difficulty driving at night. Astigmatism can be diagnosed through a comprehensive eye exam, and treatment options include corrective lenses (glasses or contact lenses), refractive surgery (LASIK or PRK), or orthokeratology (rigid contact lenses worn overnight to reshape the cornea). Early detection and treatment of astigmatism can help prevent eyestrain and headaches.
