Whether or not a patient with astigmatism needs to wear eyeglasses is related to the degree of astigmatism. If the patient’s astigmatism is low and his or her vision is not affected, he or she can go without eyeglasses. If the patient’s astigmatism is high or if the patient has high requirements for fine vision, glasses can be worn to correct and improve vision. Astigmatism is a common ophthalmologic condition and is a type of refractive error, usually caused by congenital developmental abnormalities or poor eye habits, such as squinting to see. Patients with astigmatism can undergo an optometry examination to determine the exact degree of astigmatism and the axis of astigmatism. Generally, low degrees of astigmatism have a lesser impact on vision, and the patient can be exempted from wearing eyeglasses. If the patient’s astigmatism is high or if the patient has a high demand for fine vision, then the patient can wear glasses for correction to improve vision. It is recommended that patients with astigmatism consult a doctor to evaluate their condition and follow the doctor’s instructions for treatment.
