The paper analyzes the imaging properties of the light sword optical element (LSOE) applied as a contact lens to the presbyopic human eye. We performed our studies with a human eye model based on the Gullstrand parameterization. In order to quantify the discussion concerning imaging with extended depth of focus, we introduced quantitative parameters characterizing output images of optotypes obtained in numerical simulations. The quality of the images formed by the LSOE were compared with those created by a presbyopic human eye, reading glasses and a quartic inverse axicon. Then we complemented the numerical results by an experiment where a 3D scene was imaged by means of the refractive LSOE correcting an artificial eye based on the Gullstrand model. According to performed simulations and experiments the LSOE exhibits abilities for presbyopia correction in a wide range of functional vision distances.
本文分析了用作老花眼人眼隐形眼镜的光剑光学元件（LSOE）的成像特性。我们使用基于古尔斯特兰德参数化的人眼模型进行了研究。为了量化关于扩展焦深成像的讨论，我们引入了表征数值模拟中获得的视标输出图像的定量参数。将LSOE形成的图像质量与老花眼人眼、老花镜和四次反轴棱锥形成的图像质量进行了比较。然后，我们通过一个实验对数值结果进行了补充，在该实验中，基于古尔斯特兰德模型的人工眼通过折射LSOE对3D场景进行成像。根据所进行的模拟和实验，LSOE在广泛的功能性视觉距离范围内具有矫正老花眼的能力。
