A 7 year old child has 300 degrees of myopia, and it is impossible to predict the amount of myopia he or she will have as an adult.
Myopia is prevalent in children and adolescent patients and can lead to blurred vision in affected children. Myopia is usually caused by a combination of genetic factors and poor eye habits, and may gradually increase with age. However, due to individual differences and different eye habits, it is not possible to accurately predict the amount of myopia a child will experience in adulthood.
At present, myopic children need to develop good eye habits to prevent myopia from increasing, such as doing more outdoor exercise and looking at fewer electronic products such as cell phones, TVs and computers.
Children with myopia are advised to visit the hospital in time to assess their condition and under the guidance of their doctor.
