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.

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力是通过超市和药店的低成本视力检查亭显着改善所有美国人获得视力保健的机会。实现商业化和可扩展性的一个关键技术组成部分是开发一种非接触式自动眼科扫描仪，可以在10秒内准确测量处方数量。该信息亭使美国人平均每年访问20-30次的零售商能够提供即时视力检查和报告，由医生远程审查眼科处方，并获得高质量但负担得起的矫正眼镜。有1.75亿美国人受益于视力矫正，这一解决方案可能会对所有社区的视力保健产生深远的影响。这个小型企业创新研究（SBIR）第一阶段项目研究了一种新型非接触式眼睛验光仪用于药店和超市自助和自主视力保健站的可行性。眼睛扫描是通过光折射原理，使自主眼屈光在短短几秒钟内完成。一个关键的问题与领先的照片折射配置是所产生的漂移源于凝视错位。代替在视野中的单个位置折射，所提出的新配置同时折射中心和周边视野，从而保证测量中心凹屈光不正。这种新颖的配置将使用常用的低成本组件，并可以在一小部分的商业自动验光仪的成本制造。将使用系统的软件模型来有效地优化配置，之后将构建和测试设计。将开发一个物理模型眼并用于测试，以确认在多个注视角度下的准确性，并确认注视对准的结果解耦。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
