Astigmatism is a common eye condition that causes blurred vision. It occurs when the cornea, the front part of the eye, is curved or has an irregular shape. This prevents light from entering the eye in a focused manner, creating a distorted image. Astigmatism is usually present from birth, but it can also develop later in life.
Common Causes of Astigmatism
Astigmatism can be caused by a number of factors, including genetics, trauma to the eye, and eye diseases.
Genetics: Astigmatism can be inherited from a person’s parents. In some cases, both parents may have the condition, while in others, only one parent may have it.
Trauma: Trauma to the eye or head can cause astigmatism. This includes physical force, such as a punch or a sports-related injury, as well as medical procedures, such as eye surgery.
Eye Diseases: Certain eye diseases, such as keratoconus, can cause astigmatism. Keratoconus is a condition in which the cornea of the eye gradually becomes thinner and takes on a cone-like shape.
Treating Astigmatism
Astigmatism can be treated with corrective lenses, such as eyeglasses or contact lenses. In some cases, surgery may be necessary to correct the shape of the cornea. Surgery is usually only recommended for severe cases of astigmatism.
