Astigmatism can be improved by wearing corrective eyeglasses, corneal refractive surgery and maintaining healthy eye habits. 1. Wearing corrective glasses: Astigmatism is caused by different refractive ability of different parts of the eye, which leads to the light not being able to converge to the same point of the retina. Astigmatism can be accurately measured by professional optometry machines, and corrective glasses can be made according to the astigmatism to improve the condition. 2. Keratoconus surgery: Wearing corrective glasses is simple, but it needs to be worn permanently and cannot solve the problem at all. Corneal laser surgery, corneal rim release incision, intraocular refractive surgery, refractive lens implantation and other surgeries can cure most of astigmatism. 3. Maintain healthy eye habits: Pay attention to reasonable rest of the eyes, and moderate outdoor activities to relieve eye fatigue. Avoid prolonged use of the eyes, frequent rubbing of the eyes, excessive exposure to dust and other substances, and prolonged exposure to dim or bright light.
