Title: (EN) Multifocal ophthalmic spectacle lens arranged to output a supplementary image
Abstract: front page image
(EN)

A multifocal ophthalmic spectacle lens (10) capable of correcting a wearer's ophthalmic vision and having a back surface (BS) and a front surface (FS), said lens comprising a light guide optical element arranged to output a supplementary image (SI) to the wearer through an exit surface (ES) of said light guide optical element, where the exit surface (ES), the back surface (BS) and an optical material located between said exit surface (ES) and said back surface (BS) form an optical device (OD) and wherein said optical device (OD) comprises an area of stabilized optical power.
