What is the adult vision standard?

The standard of adult vision is 1.0 or 5.0. At

present, there are logarithmic and decimal visual acuity charts commonly used in clinical practice. If logarithmic visual acuity chart is used for examination, adult normal vision should generally reach 5.0; if decimal visual acuity chart is used for examination, adult normal vision should generally reach 1.0. If the patient's naked vision does not meet this standard, it is suggested that the patient's vision is abnormal. It is recommended that the patient go to the hospital for relevant examinations in time.

Daily attention should be paid to developing correct eye habits. Do not use electronic products for a long time, and do not overuse eyes.
