Abstract: Systems and methods for preventing sight deterioration caused by near work with devices with electronic screens arc provided. A system can include, in addition to an electronic screen, a distance detector directed towards a user. A system can also include processing circuitry coupled to a distance detector. Processing circuitry determines the distance between a user's head and a screen, relative to a calibration distance, and in case it is shorter than the calibration distance (putting the user at risk of future sight deterioration and progression of myopia), it can send a control signal to circuitry operative to notify the user. If processing circuitry determines that said distance is equal or longer than the calibration distance, the circuitry operative can slop the notification. A notification can be modulated by stud relative distance, making a user instinctively move a device away.
