An electrically-controlled optical device intended to be placed in front of a user's eye, the electrically-controlled optical device being an ophthalmic device, the electrically-controlled optical device comprising: a front shell defining a front surface and a back surface opposed to the front surface, the front shell comprising a slab, at least one functional layer arranged on the back surface and one primer layer, said primer layer being arranged between the at least one functional layer and the slab; and an electrically-controlled object facing the back surface of the front shell wherein the primer layer is conformed such that the electrically-controlled optical device is mechanically resistant to an impact energy of at least 200 mJ.

Electrically-controlled optical device with a front shell

An optical lens intended to be placed before a wearer's eye and having a front surface and a rear surface, the rear surface being the surface intended to be the closest to the wearer's eye when the optical lens is placed before a wearer's eye, the optical lens having a mineral glass element on the front surface and further comprising an eye protector that is configured to prevent any piece of the mineral glass element from reaching the wearer's eye when the element is broken, said eye protector comprising a polymer wafer arranged on the rear surface.

Optical lens

Active optical filter adapted for a spectacle lens, the active optical filter being configured so as to filter light radiations over at least one predetermined range of wavelengths, wherein the full width at half maximum of the filtering function of the optical filter is smaller than or equal to 100 nm.
