SBIR Phase I: Vision care station for on-demand rapid examination of visual performance.

这个小型企业创新研究(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著改善所有美国人获得视力护理的机会。实现商业化和可扩展性的一个关键技术组件是开发一种非接触式自主眼睛扫描仪，它可以在10秒内准确测量处方数量。该售货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，医生远程查看眼科处方，以及获得高质量但负担得起的矫正眼镜。随着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护理产生深远影响。这个小型企业创新研究(SBIR)第一阶段项目调查了一种新型非接触式屈光镜的可行性，该屈光器用于药店和超市的自助式和自主视力护理站。眼睛扫描是通过光折变原理完成的，使眼睛在短短几秒钟内自主屈光。领先的折光镜配置的一个关键问题是由于凝视不对准而导致的漂移。这种新型结构不是折射视野中的单一位置，而是同时折射中心视野和周边视野，从而保证了中心凹屈光误差的测量。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折射器的一小部分成本制造。系统的软件模型将被用来有效地优化配置，之后将建立设计并进行测试。将开发一个物理模型眼并用于测试，以确认在多种凝视角度下的准确性，并确认凝视对准的结果脱钩。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

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.
