Astigmatism in a three-year-old baby can be corrected through general treatment, wearing framed glasses, corneal contact lenses, and surgical procedures.

1. General Treatment

If a three-year-old baby has astigmatism without affecting normal vision or causing significant discomfort, they can adjust their eye usage habits by avoiding prolonged close-up exposure to electronic devices and ensuring sufficient sleep time. This can help alleviate the symptoms of astigmatism to a certain extent.

2. Wearing Framed Glasses

If the degree of astigmatism is severe and has already impacted normal life, it is necessary to consult an ophthalmologist at a reputable hospital and undergo relevant examinations. Then, under the doctor's guidance, wearing framed glasses can be used to improve the condition and achieve the purpose of correcting astigmatism.

3. Corneal Contact Lenses

If the astigmatism is relatively severe, corneal contact lenses can also be prescribed for correction to improve blurred vision.

4. Surgical Treatment

If the above methods are ineffective and the baby has reached 18 years of age, laser surgery or other surgical procedures can be considered for treatment. These treatments are usually effective in improving astigmatism.

In daily life, it is important to maintain a reasonable diet, primarily consisting of light and easy-to-digest foods such as millet porridge and pumpkin porridge. Adequate rest and avoiding overexertion are also crucial. If any significant discomfort occurs during this period, immediate medical attention is necessary to avoid delaying treatment.
