A student’s visual acuity of 4.8 indicates that vision loss has occurred, but it is not always due to myopia.
Under normal circumstances, naked eye vision should reach 5.0. Preschool children may not be able to reach 5.0 temporarily due to the imperfect development of the eyeballs, but they should continue to be observed.
If a student’s naked eye visual acuity is only 4.8, it is below normal, indicating that there is a loss of vision. Since many ophthalmologic diseases can cause a loss of vision, it is not possible to attribute the loss of vision to myopia at this time. Common causes include astigmatism, amblyopia, congenital cataracts, and fundus lesions.
At present, the patient’s visual acuity of 4.8 should go to the ophthalmology department of the hospital for examination in time, and the doctor will diagnose whether it is caused by myopia or other reasons through the relevant examination, and then carry out the treatment according to the specific reasons.
