Abstract: A diffractive, multifocal ophthalmic lens including an apodization zone with echelettes having a smoothly reduced step height to shift the energy balance from the near image to the distant image and thus reduce the glare perceived when viewing a discrete, distant light source.

Abstract translation: 一种衍射多焦点眼科镜片，其包括具有小阶梯的变迹区，其具有平滑降低的台阶高度，以将能量平衡从近图像转移到远距离图像，从而减少当观察离散的远距离光源时感知到的眩光。
