This project seeks to further develop and test to a level of consumer-ready prototypes a new, Conducting Polymer (CP) based electrochromic (EC) technology for persons with Age-Related Macular Degeneration (ARMD) as well as other age-related ocular diseases. It is based on our prior work at the Atlanta Veterans Administration Rehabilitation R&D Center with EC sunglasses tested on ARMD subjects, and on new, CP EC technology originally developed at this firm for office/auto windows. In the prior work, it was shown that the functional vision and mobility performance of people with ARMD significantly improves with EC sunglasses. In the Phase I work, excellent EC lens performance was demonstrated: 3% to 83% light/dark contrast; 1 to 3 sec switching time; thin (l.t. 3 mm), flexible (plastic), solid-state construction, cyclability g.t. 5,000 cycles. A sophisticated Controller (hardware/software) for ambient-light dependent control of sunglasses was demonstrated. Subject testing on 9 ARMD patients showed a real performance difference in simulated outdoor environment. In the present project, the EC performance of the lenses will be further refined, 100 EC glasses with a more sophisticated hearing-aid- sized Controller fabricated, and patient testing on 25 (Year 1) and 100 (Year 2) patients demonstrated. PROPOSED COMMERCIAL APPLICATION: Prior research has shown that such fast-darkening sunwear would also appeal to the general, normal-sighted populace, in addition to the 2 M people with ARMD and more than 1 M with other age-related ocular problems in the US. Thus, if as expected the EC sunglasses are producible for l.t. US $250, they would command a large market.

该项目旨在进一步开发和测试，以一种基于与年龄相关的黄斑变性（ARMD）以及其他与年龄相关的眼部疾病的人以及基于年龄相关的黄斑变性（ARMD）的人的新型，指导聚合物（CP）的电致聚合物（CP）。它基于我们在亚特兰大退伍军人管理康复研发中心的先前工作，其EC太阳镜对ARMD受试者进行了测试，以及最初是在该公司开发的新型CP EC技术上，用于Office/Auto Windows。在先前的工作中，证明ARMD患者的功能视觉和移动性能通过EC太阳镜显着改善。在第一阶段的工作中，证明了出色的EC镜头性能：3％至83％的光/深色对比； 1至3秒切换时间；薄（L.T. 3毫米），柔性（塑料），固态结构，可环性G.T. 5,000个周期。展示了用于对环境光的依赖太阳镜的复杂控制器（硬件/软件）。对9名ARMD患者进行的受试者测试在模拟室外环境中显示出真正的性能差异。在本项目中，将进一步完善镜头的EC性能，100张EC玻璃杯，具有更复杂的助听器尺寸控制器，并在25（1年）和100年（2年级）（2年级）患者进行了患者测试。拟议的商业应用程序：先前的研究表明，除了2 m的ARMD和1 m的患者外，这种快速黑的阳光也将吸引一般，正常的人群，在美国其他与年龄相关的眼部问题。因此，如果正如预期的那样，EC太阳镜可用于L.T. 250美元，他们将指挥大型市场。
