Is 4.6 normal?

Normal vision standards for people over six years old should reach 5.0 or 1.0. If vision is 4.6, it is lower than normal vision standards. Be sure to go to the hospital as soon as possible to see what causes it. At present, with the widespread use of mobile phones, computers and various electronic products, the incidence of various eye diseases is gradually increasing. Whether it is eye surface disease, fundus disease or refractive error will cause low vision, so be sure to go to the hospital to improve the relevant examination, to see what type of disease. If the fundus disease, often retinal detachment, macular degeneration, macular edema, inflammation of the optic nerve, fundus bleeding or vitreous hemorrhage. The diseases of the eye surface include conjunctivitis, keratitis and the like, but conjunctivitis rarely affects vision, and the most common factor affecting vision is refractive error.
