How astigmatism is caused

The main causes of astigmatism are curvature and exponential astigmatism, and corneal diseases, corneal degeneration, cataracts, and corneal surgery can also cause astigmatism.

1. Main causes

1. Heredity: heredity is the main factor of astigmatism, according to clinical data statistics, the probability of astigmatism in minors with astigmatism in either parent is much higher than the probability of astigmatism in minors with both parents.

2. Bad habits: Maintaining bad eye habits for a long time, such as lying down and reading, often rubbing and squinting, is easy to compress the cornea, which changes the shape of the cornea, and then leads to astigmatism.

3. Diseases: Astigmatism can also occur after curing of some eye diseases, such as keratoconus, corneal ulcer, keratitis, pterygium, etc.

4. Trauma and surgery: When corneal damage occurs and some eye surgery errors occur, keratoconus may be caused, and astigmatism may occur.

2. Predisposing factors

1. Advanced age: the probability of astigmatism increases significantly with age, which may be related to the natural aging of the human body, and is generally more common in the elderly over 65 years old.

2. Malnutrition: When the human body is malnourished, the hardness of the cornea will decrease significantly, and the risk of corneal astigmatism will increase.

3. Obesity: According to relevant research statistics, among clinical astigmatism patients, there are significantly more obese minors than normal minors.
