The visual acuity of a person with 100 degrees of myopia can be tested using a visual acuity chart. Visual acuity testing is usually done with a standardized visual acuity chart. First, you need to sit 5 meters in front of the standardized visual acuity chart, cover your eyes in turn, and check the visual acuity of each eye. Under normal circumstances, the naked eye visual acuity should reach 1.0. If the myopia is 100 degrees, the general visual acuity examination can be found that the patient’s naked eye visual acuity decreased. Myopia of 100 degrees is usually the refractive error obtained through refraction, while visual acuity is the acuity of vision detected through the visual acuity meter, the two are not directly related. It is recommended that myopic patients seek medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
