Checking the prescription of the eyes mostly refers to optometry, which can find out whether the patient has astigmatism and the degree of astigmatism. Checking the degree of the eye is actually checking the state of the refractive error of the eye, and the refractive error includes three types of myopia, hyperopia, and astigmatism. When doing an optometry test, it is possible to determine which type of refractive error the patient is suffering from as well as to arrive at the specific degree of refractive error, and therefore to check whether the patient is suffering from astigmatism. Patients with astigmatism can find out the exact degree of astigmatism and the axial direction of astigmatism and other important parameters. If astigmatism affects the patient’s vision, he or she can wear the appropriate glasses according to the results of the optometry examination to correct and improve his or her vision. Astigmatism patients should also develop good eye habits, especially pay attention to not squinting for a long time to see things, otherwise it may aggravate the degree of astigmatism. It is recommended that patients with astigmatism with obvious symptoms should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
