Tunable apodized multiple-focus ophthalmic devices and methods characterized by a lens with multiple optical zones each with an optical power optimized for one or more focal lengths and a tunable apodization mask positioned within at least a portion of the optical zone(s). Upon a desired change of focus for the wearer, an optical transmission characteristic of the tunable apodization mask may be varied. The tunable apodization mask may take the form of an electrochromic device or another suitable material.可調整切趾(apodized)多焦眼用裝置及方法，其特徵在於：一鏡片，其具有多個光學區，該多個光學區各自具有針對一或多個焦距所最佳化的一光學度數；及一可調整切趾罩(apodization mask)，其經定位在該(等)光學區之至少一部分內。在配戴者的一所欲聚焦變化時，可改變該可調整切趾罩之光學透射特性。該可調整切趾罩可採取一電致變色裝置或另一合適材料的形式。
