Generally speaking, if the myopia exceeds 100 diopters, or if the patient’s naked eye visual acuity falls below 0.8, glasses are needed.
Patients with myopia should go to the ophthalmology department of the hospital for examination in time. Usually, it is necessary to do naked-eye visual acuity examination, optometry examination, slit-lamp microscopy examination, funduscopy examination, and corrective vision examination, etc., in order to clarify the current refractive state and visual acuity.
For myopic patients with myopia of less than 100 diopters, if the naked-eye visual acuity can reach 0.8 or above, it usually does not cause any inconvenience in life due to lack of clarity, so they can not wear glasses for a while.
However, if the patient’s myopia is more than 100 degrees, the naked eye visual acuity has decreased to less than 0.8, you should wear glasses to correct it, otherwise it will not only cause inconvenience in life, but also may increase the fatigue and cause myopia to grow.
Occurrence of myopia is recommended to consult a doctor for examination, specific whether glasses should follow the doctor’s advice.
