Method for the recovery and repair of eyesight through which out of the two eyes the weaker eye in need of repair or recovery is determined both eyes are assigned an optical element influencing the passage of the incident light the path of the light reaching the eye is periodically interrupted, thereby forcing the eye to perform additional focusing activity, so that transparency characteristics of the optical element assigned to the chosen or designated eye are left unchanged, and the transparency characteristics of the optical element assigned to the other eye are modulated so that the passage of incident light into the other eye is blocked and then unblocked with a frequency in the 0.2 Hz to 0.8 Hz range.Corrective eyeglass composed of an eyeglass frame designed for holding and positioning the eyeglass on the head containing two fixed optical elements influencing the passage of the received light, a control unit exerting temporal control over the optical characteristics of said optical element, and one power supply unit supplying at least one optical element and at least one control unit with electrical energy, wherein the optical element influencing the passage of incident light is embodied as a controlled light shutter, at least one control unit is electrically connected to the control unit, and said control unit is embodied as a control unit influencing the optical characteristics of at least one optical element based on a pre-defined controlling signal and providing asymmetric control with a frequency in the range of 0.2 Hz to 0.8 Hz to the optical elements.
