This reference distance can for example be set at between 20 and 50 cm depending on the spectacle wearer. A kit is also provided comprising a frame, telemetry means and an alarm. The spectacle frame can be prescribed for slowing down the evolution of acquired myopia in children who are starting to acquire myopia; here, the spectacle frame is provided with progressive multifocal lenses.
