Abstract: A system and method for preventing sight deterioration caused by prolonged use of electronic visual displays in low-light conditions is provided. The system includes a camera directed towards a user, a processing circuitry, control circuitry and, optionally, a light sensor. The processing circuitry determines the illuminance of a user's face, and in case it falls outside of a predefined range (putting the user at risk of future sight deterioration and progression of myopia), the device stores the illuminance data and/or sends a control signal to circuitry operative to notify the user. If processing circuitry determines that the illuminance is equal or greater than the predefined illuminance, the circuitry operative can stop the notification. The notification can be modulated by any combination of the illuminance and the time of use.

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.
