Lutein has not been found to be effective in treating astigmatism. Astigmatism is caused by congenital developmental abnormalities or bad eye habits such as ptosis, long-term squinting, etc. It is related to the inconsistency of the refractive power of the refractive system of the patient’s eyes in different directions, and taking lutein cannot change this situation. Patients with astigmatism may experience symptoms such as decreased visual acuity, double vision, etc. Patients can wear eyeglasses to correct their astigmatism and improve their vision as prescribed by their doctor. If the patient does not want to wear glasses, astigmatism can also be corrected through surgery, such as corneal laser surgery, intraocular lens implantation and so on. If the astigmatism is caused by squinting for a long time, patients also need to improve their eye habits to avoid astigmatism aggravation. Patients with astigmatism are advised to consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
