Although good or bad visual acuity can have a certain reflection on the degree of myopia, but the two represent different meanings, 4.7 visual acuity can not be converted to the patient’s specific degree of myopia.
Patients through the vision meter test is the visual acuity data, mainly reflecting the macular retina of the eye on the external things imaging ability, and myopia is a completely different concept. There is no one-to-one quantitative relationship between myopia and myopia, and it is not possible to speculate the degree of myopia based on the patient’s visual acuity of 4.7.
Myopia can lead to vision loss, and generally the higher the myopia, the more significant the vision loss. However, even patients with the same amount of myopia do not have the same visual acuity.
It is recommended that patients with vision loss seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
