The pandemic condition forces us to do physical distancing, and this has an impact on the child's learning system. Children learn at home using assisted technology. The impact that occurs is that children's screen time becomes longer, and the results of the study show that eye complaints in children are increasing. Based on this, the purpose of this study is to propose a real time system that can monitor the distance between the eyes and the screen, besides that this system can monitor the intensity of light in the children's study room when online learning takes place. This system is also designed to be able to monitor the duration when children are in front of the monitor. The experimental results show that this system can work well in real time. It is hoped that this system can reduce children's eye complaints caused by long screen time.
