Nowadays, children use mobile phones more and more. And more and more teenagers are wearing glasses. What's wrong The academic world has the answer. Electronic devices emit harmful blue light, which may harm our eyes. As a result, the longer the child uses the mobile phone, the faster his or her myopia will be. To this end, the Institute of Child Health has developed a device called a cell phone portable jammer.

The device may emit radio interference, which effectively prevents signal transmission from the mobile phone network. This can effectively prevent children from using the phone for a long time. The device is currently very popular among parents in Europe. In the US, certain trends are beginning to become popular, and it is estimated that in the future, families with young children will have a jammer.
