The broader impact /commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to significantly improve access to vision care for all Americans via a low-cost vision exam kiosk for supermarkets and pharmacies. A key technical component for reaching commercialization and scalability is the development of a contactless and autonomous eye scanner that accurately measures prescription numbers in under 10 seconds. The kiosk enables retailers that Americans already visit on average 20-30 times per year to offer instant vision exams and reports, eye prescriptions reviewed remotely by physicians, and access to high quality but affordable corrective eyewear. With 175 million Americans benefiting from vision correction, this solution could profoundly impact vision care across all communities. This Small Business Innovation Research (SBIR) Phase I project investigates the feasibility of a novel contactless eye refractor for use in a self-serve and autonomous vision care station for pharmacies and supermarkets. Eye scanning is done via the photo-refractive principle enabling autonomous ocular refraction in mere seconds. A key issue with leading photo-refractor configurations is the resulting drift stemming from gaze misalignment. Instead of refracting single positions in the visual field, the proposed novel configuration refracts the central and peripheral visual field simultaneously, thus guaranteeing the measurement of foveal refractive error. This novel configuration will use commonly available low-cost components and can be manufactured at a fraction of the cost of commercially autorefractors. A software model of the system will be used to efficiently optimize the configuration, after which the design will be built and tested. A physical model eye will be developed and used for testing to confirm the accuracy at a multitude of gaze angles and to confirm result-decoupling of gaze alignment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I阶段项目的更广泛的影响 /商业潜力是，通过对超市和药房的低成本视觉考试亭可显着改善所有美国人的视觉护理。达到商业化和可伸缩性的关键技术组成部分是开发非接触式和自主眼扫描仪，该扫描仪可以在10秒钟内准确测量处方数量。售货亭使零售商每年平均每年20-30次访问零售商，以提供即时视觉考试和报告，医生远程审查的眼部处方以及获得高质量但负担得起的纠正式眼镜。由于1.75亿美国人受益于视力校正，因此该解决方案可能会对所有社区的视力护理产生深远的影响。这项小型企业创新研究（SBIR）I阶段项目研究了一种新型的非接触式眼折射器，可用于药房和超市的自助服务和自主视觉护理站。眼睛扫描是通过仅在短短几秒钟内实现自主眼折射的光赋予原理进行的。领先的光折射配置的关键问题是凝视未对准的造成的漂移。所提出的新型配置不是在视野中折射单个位置，而是同时折射中央和外围视野，从而确保了中央凹折射误差的测量。这种新颖的配置将使用常见的低成本组件，并且可以以商业自动磨砂器的成本的一小部分制造。系统的软件模型将用于有效地优化配置，然后将设计和测试设计。将开发和用于测试物理模型的眼睛，以确认众多凝视角度的准确性，并确认凝视对齐的结果。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力优点和更广泛的影响审查标准通过评估来进行评估的。
