what is an eye astigmatism

Astigmatism is a common eye condition that causes blurred or distorted vision at all distances. It occurs when the cornea or lens of the eye has an irregular shape, causing light to bend unevenly as it enters the eye. This makes it difficult for the eye to focus light properly on the retina, resulting in blurry vision. Astigmatism can be present at birth or develop after an eye injury, disease, or surgery. Symptoms of astigmatism include blurry or distorted vision, eyestrain, headaches, and difficulty seeing at night. Treatment options include corrective lenses or surgery
