Definition: Astigmatism is a condition in which an individual's eye lens appears to be bent or distorted. This can cause vision problems and may also affect other aspects of the person's life, such as sports performance or job performance. Astigmatism can be caused by various factors, including genetic predisposition, age-related changes, and certain medical conditions like glaucoma. Treatment for astigmatism varies depending on the underlying cause and severity, with some patients needing surgery to correct their vision.
