According to a first aspect, the invention relates to an electrically controlled focusing ophthalmic device (43) to be worn by a user, comprising:—at least one active liquid lens comprising a liquid/liquid interface movable by electrowetting under the application of a voltage,—a driver for applying a DC voltage to said active liquid lens, the amplitude of the voltage to be applied being a function of the desired focusing；—a sensor (41) for detecting eyelid closing events and/or microsaccades of the user；—a controller for synchronizing said sensor and the driver, such that the driver may reverse the polarization of the DC voltage during a microsaccade and/or an eyelid closing event of the user.
