Astigmatism is a refractive error of the eye where the cornea or lens has an irregular shape, causing light to focus unevenly onto the retina. This leads to blurred or distorted vision at all distances. Common symptoms include eyestrain, headaches, and difficulty seeing fine details.
Astigmatism often occurs alongside nearsightedness or farsightedness. It can be diagnosed through a comprehensive eye exam and corrected with eyeglasses, contact lenses, or refractive surgery.
Treatment aims to compensate for the irregular curvature of the cornea or lens, enabling light to focus properly on the retina and restoring clear vision.
