A 10 year old child with 4.7 visual acuity measured at school is usually abnormal and the cause of the vision loss needs to be found. Under normal circumstances, a 10 year old child should have a visual acuity of 5.0 or more. If the visual acuity is tested at 4.7 on the optic meter, it means that the child’s vision has decreased and it is an abnormal manifestation. It may be caused by myopia, hyperopia, astigmatism, cataracts, etc., and is therefore abnormal.
The child should cultivate good reading habits in daily life, not lying down to read or play with cell phone, not reading or playing with cell phone on public transportation, and guarantee sufficient sleep time so that the eyes can have sufficient rest to protect the eyesight.
It is recommended that children with vision loss should seek timely medical attention to assess their condition and follow the doctor’s instructions for treatment to avoid delays.
