There is no way to accurately estimate a patient’s vision based on the amount of myopia, but patients can have a clear vision test to determine the level of vision.
Myopia is a common ophthalmic disease, a type of refractive error, usually the higher the degree of myopia, the greater the impact on the patient’s vision. 400 degrees of myopia belongs to the moderate myopia, which will have a significant impact on the patient’s vision, but due to the existence of individual differences, the tolerance level of the same degree of myopia varies from patient to patient, and thus the degree of vision loss is also not the same.
At present, it is impossible to accurately speculate the patient’s visual acuity based only on the degree of myopia, if the patient wants to know the current visual acuity, it is necessary to do a vision examination to make it clear.
Patients with myopia are advised to visit the hospital in time to assess their condition and follow the doctor’s instructions for treatment.
