What is Astigmatism? Causes, Symptoms, Diagnosis and Prevention.
Astigmatism is a common vision condition that occurs when the cornea or lens of the eye is irregularly shaped, causing light to refract incorrectly and resulting in blurry or distorted vision. The cornea is the clear, dome-shaped outer covering of the eye, and the lens is a clear structure located behind the iris that helps to focus light onto the retina. In people with astigmatism, the cornea or lens is not perfectly round, but rather is more oval-shaped, like a football instead of a basketball. This irregular curvature prevents light from being focused evenly onto the retina, leading to blurred or distorted vision.
Causes of Astigmatism
The exact cause of astigmatism is unknown, but it is believed to be a combination of genetic and environmental factors.
