Presbyopia is an age-related loss of accommodation ability of the eye which affects individuals in their late 40s or early 50s. Presbyopia reduces the ability of a person to focus on closer objects at will. In this study, we assessed electronically tunable lenses for their aberration properties as well as for their use as correction lenses. The tunable lenses were evaluated in healthy subjects with cycloplegia by measuring visual acuity and contrast sensitivity for their use in presbyopia correction. Furthermore, we have developed and demonstrated the feasibility of a feedback mechanism for the operation of tunable lenses using a portable solid-state LIDAR camera with a processing time of 40 ± 5 ms.
老花眼是一种与年龄相关的眼睛调节能力丧失，影响40多岁后期或50岁初期的人群。老花眼会降低人随意聚焦较近物体的能力。在本研究中，我们评估了电子可调透镜的像差特性以及它们作为矫正透镜的用途。通过测量视力和对比敏感度，在患有睫状肌麻痹的健康受试者中评估可调透镜用于老花眼矫正的情况。此外，我们开发并证明了一种反馈机制的可行性，该机制使用处理时间为40±5毫秒的便携式固态激光雷达相机来操作可调透镜。
