Nowadays，the popularization of electronic devices such as TV, computers and ipods has lead to the severe case that people become myopia much younger than before due to overuse of these devices. To avoid status quo, we designed this computer accessory Zoom Screen particularly for kids. When they are using computers, unfold Zoom Screen just in front of the screen. Only if they kept a proper distance from the screen could they see the clearly. Sitting too far or too close to the screen would fail. Zoom Screen is a most effective way to prevent them from myopia.
