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.

Abstract: A method for determining at least one optical parameter of an eye of a person comprising displaying at least two sharp images on a retina of the eye of the person, the at least two images comprising a target and being carried by two light beams focused substantially in the plane of a pupil of the eye at at least two different positions, adapting a parameter of the target in each image based on feedback of the person relative to the change of the parameter of the target in the image, and determining the at least one optical parameter of the person's eye based on the adaption of the parameter of the target in each image.
