Abstract: An eyeglass device including a variable transmission ophthalmic lens, a method for driving the transmission of such lens, and a non-transitory computer-readable storage medium for implementing such method. The eyeglass device comprises a light sensor configured for measuring an amount of light in the environment of a wearer and a controlling circuit configured for receiving at least light data from said light sensor and for driving the transmission of said ophthalmic lens on the basis of said light data. The controlling circuit is configured for driving the transmission of said ophthalmic lens on the basis further of movement data, said movement data being derived from an estimation of a movement of the wearer's head.
