DESCRIPTION: Diplopia is usually corrected by spectacle lenses with prismatic corrections. Such spectacles are thick, heavy and uncomfortable. Fresnel press-on prisms overcome the thickness problem but suffer from a number of other problems such as reduction in contrast sensitivity and acuity, noticeable lines and deterioration of optical quality due to trapped air bubbles. Proposed optical elements have the potential of correcting diplopia without these deficiencies. The specific aim of phase I would be to design and fabricate the proposed optical elements on flat substrates and to establish their efficacy in correcting diplopia. These element, however can be fabricated on a surface with curvature (both concave and convex) as well. Use of these optical elements in combination with conventional spectacles with refractive corrections as well as their use for other vision applications would be the longer term objective of the project. Well established technology exists to fabricate and replicate (thus mass produce at low cost) these optical elements. In Phase I, we will optically measure and analyze the prototype elements and conduct human subject trials at a clinical facility.

描述：复视通常由眼镜片矫正， 棱镜校正 这种眼镜又厚又重， 不舒服 菲涅耳压装棱镜克服了厚度问题 但是存在许多其它问题 敏感度和敏锐度，明显的线条和光学退化 质量是由于被困的气泡。 所提出的光学元件具有 矫正复视的潜力而没有这些缺陷。 的 第一阶段的具体目标是设计和制造拟议的 光学元件，并确定它们在 矫正复视 然而，这些元件可以制造在 曲面（包括凹面和凸面）。 使用这些 光学元件与传统眼镜的组合 屈光矫正及其在其它视觉应用中的应用 这将是该项目的长期目标。 很好地建立 存在制造和复制的技术（因此以低成本大规模生产）。 成本）这些光学元件。 在第一阶段，我们将光学测量和 分析原型元素并进行人体试验， 临床设施。
