The examinee’s visual acuity of 5.2 is normal, but it is not possible to speculate on the degree of myopia of the examinee, because myopia and visual acuity do not correspond to each other. Generally, the higher the degree of myopia, the more obvious the patient’s vision loss, but the visual acuity and the degree of myopia do not have a one-to-one quantitative relationship, so it is not based on the patient’s visual acuity, to speculate on the patient’s degree of myopia. If the patient needs to be clear about his or her degree of myopia, the patient needs to go to the hospital for an optometry examination. The normal standard visual acuity for adults is 5.0 and above, so if the examined person’s visual acuity is 5.2, then it belongs to the normal visual acuity range Patients should maintain good living habits and avoid using electronic products for a long time to maintain better vision. Patients with vision loss are advised to seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
