Hello, I heard from a friend that ophthalmology is a major to help teenagers correct myopia and help control the deepening of myopia in children. You can see for yourself. In fact, there are many brands of plastic mirrors, mainly depending on which brand the child's eye data is suitable for. Give you a suggestion, you can compare it from the aspects of wearing safety, wearing effect and price. After all, cost performance is very important. Orthokeratology can control the deepening of myopia, but pay attention to hygiene and wear it according to the instructions. After wearing it, you need to check it regularly to pay attention to your child's eye health and recovery in real time.
