Ten-year-olds have reached adult vision standards, and if their naked eye vision is below 1.0, they should pay enough attention to consider whether they have an eye disease or refractive error. If eye disease is ruled out, the possibility of myopia should be considered. Children with myopia are known to show early signs of myopia, such as not being able to see the blackboard clearly in class, tilting their heads, squinting, watching TV and doing homework in front of the books and TV. The easiest and most reliable way to determine if a child has myopia is to go to the hospital for a dilated eye exam and to be diagnosed with myopic refractive error through medical optometry. If there is already myopic refractive error, the child should be given glasses, keratoplasty lenses, and low concentration atropine to slow down the development of myopia. At the same time of the first optometry, establish a visual health file for six months, review vision once, and optometry once a year to ensure no less than one hour of outdoor activity and sunlight every day. Close eye use should be done in a relaxed manner, often do eye exercises or look at distant greenery to give the eyes sufficient rest and ensure sufficient sleep every day.
