Passive ophthalmic optic devices correct refractive defects of the eye but are not designed to employ neural adaptation processes. An extended depth of focus technology is implemented on conventional refractive devices, such as spectacles and contact lenses, and its testing is described. This technology is capable of simultaneously correcting all refractive errors, such as myopia, hyperopia, presbyopia, regular/irregular astigmatism, as well as their combinations. This is achieved by exploiting the capacity of the visual system for adaptation to contrast as well as its capability of creating a coherent continuous visual field out of discrete lines of sight.
被动式眼科光学器件可矫正眼部的屈光缺陷，但并非设计用于利用神经适应过程。扩展景深技术已应用于常规的屈光性设备，如眼镜和隐形眼镜，并对其测试进行了描述。该技术能够同时矫正所有屈光不正，如近视、远视、老花、规则/不规则散光以及它们的组合。这是通过利用视觉系统对对比度的适应能力以及将离散视线创建为连续一致的视觉场的能力来实现的。
