DESCRIPTION (provided by applicant): As the popularity of refractive surgery increases, so does the need for an accurate evaluation tool for glare assessment in both the pre- and post-surgical patient. There are several glare disability testing instruments currently available, however, these instruments do not accurately recreate physiologic conditions in the eye in the presence of glare. Based on the need for improved instrumentation that assesses visual performance without changing the optical parameters of the eye, InterScience proposes the development of glare disability assessment instrumentation, based on the digital micromirror array technology. The actual means of assessment will not differ from established procedures, i.e. testing visual acuity with established vision charts (IogMAR, Landolt ring, etc.) under various lighting conditions including glare. The goal of this work is to increase the flexibility in glare testing through the development of improved instrumentation. The proposed effort is aimed at the design, development, and demonstration of a digital glare testing device. The adaptability and flexibility of the device, including the presentation of dynamic glare sources, numerous contrast levels in test charts, programmable variations in size, intensity and location of the glare source, and a user friendly computer control system will be successfully demonstrated in the Phase I work.

描述（由申请人提供）：随着屈光手术的普及，对术前和术后患者眩光评估的准确评估工具的需求也越来越大。目前有几种眩光失能测试仪器，然而，这些仪器不能准确地再现眼睛在眩光存在下的生理条件。基于对在不改变眼睛光学参数的情况下评估视觉性能的改进仪器的需求，InterScience提出了基于数字阵列技术的眩光残疾评估仪器的开发。实际评估方法与既定程序无差异，即使用既定视力表（IogMAR、Landolt环等）测试视力。在包括眩光的各种照明条件下。这项工作的目标是通过改进仪器的开发来增加眩光测试的灵活性。建议的努力是针对设计，开发和演示的数字眩光测试设备。该仪器的适应性和灵活性，包括展示动态眩光源、测试图表中的多种对比度、可编程的眩光源大小、强度和位置变化，以及用户友好的计算机控制系统，将在第一阶段的工作中成功展示。
