A spectacle lens includes an activable optical filter having at least an electrochromic device and being configured to be actively switched between at least three configurations. In the first configuration, the activable optical filter is uniform. In the second configuration, the activable optical filter attenuates selectively light from a localized light source. In the third configuration, the activable optical filter is uniform. Furthermore, the chromaticity difference &#x394;Chrom between each of the configurations is smaller than or equal to 20.

Spectacle lens comprising an activable optical filter and optical equipment comprising such spectacle lens

A method for controlling an ophthalmic system including at least one optical element, at least one measuring sensor, at least one interface for communication with a communicating external electronic device, and at least one processor connected to the optical element and used to control a variation of a functionality relating to the optical element. The method includes: obtaining at least one measurement using the sensor, selecting at least one piece of information obtained by a communicating external electronic device, determining an instruction based on the measurement acquired by the sensor and the information obtained by the communicating external electronic device, and executing the instruction by the processor to control the variation of the functionality relating to the optical element.
