A myopia of 150 degrees is considered mild myopia, which can cause a patient’s vision to decrease, but does not determine the patient’s vision. Myopia can lead to vision loss, and generally the higher the degree of myopia, the more significant the loss of vision. However, there is no one-to-one quantitative relationship between myopia and visual acuity, so it is not possible to infer a patient’s visual acuity based on his or her myopia. The exact visual acuity of a patient should be determined by a visual acuity examination, or corrected acuity if the patient is wearing eyeglasses. If the patient is wearing glasses, the vision is corrected. If the patient is wearing no glasses, the vision is naked. It is recommended that myopia patients should consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment, and they should increase outdoor exercise, eat a balanced diet and use their eyes properly.
