There is no one-to-one correlation between visual acuity and the degree of myopia, and it is not possible to infer the patient’s naked eye vision based on the degree of myopia, and the patient needs to clarify the level of visual acuity through visual acuity examination. Myopia can be caused by long-term over-exertion of the eyes, incorrect eye posture and genetic factors, etc. Patients usually have symptoms such as blurred vision, decreased visual acuity and visual fatigue. The higher the degree of myopia, the more pronounced the decrease in the patient’s naked eye vision, but there is no quantitative relationship between the two, and it is not possible to speculate on the patient’s vision level based on his or her degree of myopia. When myopia occurs in the eyes, patients can go to the hospital to be equipped with glasses, under the guidance of professional doctors to wear keratoconus, frame glasses and other glasses to correct. For adult myopia patients, refractive surgery is also available, such as corneal laser surgery and crystalline lens implantation. It is recommended that myopia patients should consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions to choose the appropriate treatment.
