Presbyopia, the age-related reduction in near vision acuity, is one of the leading issues facing the contact lens industry due to an increasingly ageing population and limitations associated with existing designs. A plastic-based liquid crystal contact lens is described which is designed to allow switchable vision correction. The device is characterized by low operating voltages (<5V(rms)) and has curvatures suitable for placement upon the cornea. Imaging and Point Spread Function analysis confirm that the lens provides an increase in optical power of + 2.00 ± 0.25 D when activated, ideal for presbyopia correction.
老花眼是一种与年龄相关的近视力下降问题，由于人口老龄化加剧以及现有设计的局限性，它是隐形眼镜行业面临的主要问题之一。本文描述了一种基于塑料的液晶隐形眼镜，其设计目的是实现可切换的视力矫正。该设备的特点是工作电压低（<5V（rms）），并且具有适合放置在角膜上的曲率。成像和点扩散函数分析证实，该镜片在激活时可提供+2.00±0.25 D的屈光力增加，非常适合老花眼矫正。
