An eyeglass (10) is adapted for providing an ophthalmic vision and a supplementary vision to a wearer of said eyeglass, both ophthalmic and supplementary visions being sharp during respective periods. To this purpose, a transparent active device (3) is located between the back face (BF) of the eyeglass and a light-conducting element (2), this latter being embedded within the eyeglass and dedicated to ouput the light of the supplementary vision. The transparent active device switches between two optical power values, which are dedicated to make sharp the ophthalmic vision and the supplementary vision, respectively.
