Astigmatism is a common vision condition that causes blurred or distorted vision due to an irregular shape of the cornea, affecting how light focuses on the eye.
What Is Astigmatism?
Astigmatism occurs when the cornea or natural lens of the eye has an irregular curvature. Instead of being evenly rounded, the surface may be shaped more like an oval, causing light to focus unevenly on the retina. This results in blurred or distorted vision at all distances, not just near or far.
Astigmatism can occur on its own or alongside other refractive errors such as nearsightedness or farsightedness. Because the condition can vary in severity and presentation, accurate diagnosis is essential for effective astigmatism treatment.
