There is no one-to-one relationship between myopia and visual acuity, so you cannot accurately estimate visual acuity based on myopia alone. There is no one-to-one relationship between myopia and naked eye vision, so you can’t accurately predict naked eye vision based on myopia alone. Naked eye vision can be reduced in myopic patients, but patients need to go to the ophthalmology department of the hospital for a visual acuity examination to determine the current level of visual acuity. 500 diopters is considered moderate myopia, less than 300 diopters is mild myopia, 300 to 600 diopters is moderate myopia, and more than 600 diopters is high myopia. Myopia patients should pay attention to their eye use, and can improve their vision by getting glasses to correct myopia. Myopia patients are advised to consult a doctor in time to assess their condition and follow the doctor’s instructions for treatment.
