Abstract: A system including a sensor configured so that the presence of a spectacle within a detection range of the sensor is detectable by the sensor when the spectacle includes a predetermined identification structure. The system may further include a control unit configured to receive an information from the sensor and to carry out a predetermined action, upon a condition in which the one or more spectacle lenses may be detected. A method may include detecting the presence of the spectacle within a detection range, and further providing, by the sensor, an information to the control unit. The information may confirm the detection of the spectacle. The method may include carrying out, by the control unit, the predetermined action. A computer program product including instructions to cause the system to execute the steps of the method. A computing device including the sensor and a memory.
