摘要

本文研究目的係使用重量最佳化與偶次非球面複曲面設計一精巧型散光眼鏡鏡片。此種鏡片優點具超薄型重量輕，解像率又高。研究方法係採用ZEMAX光學設計程式的多重組態對無限遠、1000 mm、500 mm，3種視場(View Field)進行設計，使具散光眼患者在配戴精巧型散光眼鏡後也適合看遠、中、近距離。除了可矯正-1.00 D散光之外，還可以使配戴精巧型散光眼鏡之後的視網膜解像率在30 lp/mm的MTF值達0.3。

This paper studies the design of astigmatic eyeglass lens by using even aspheric toroidal surface, multi-configuration and optimizing the mass of eyeglass lens. The innovation method will provide the best solution of correcting astigmatism and minimum edge thickness of eyeglass lens. Making a human eye modal with astigmatism and the multi-configuration was defined three distances that are far, middle and near, 10.0e(superscript +09) mm, 1000 mm and 500 mm respectively, according to the human eye's adaptive function with three different view angles. The designing result of 1.0 D astigmatic eyeglass lens can largely correct astigmatism and the Modulation Transfer Function (MTF) is 0.3 at 30 lp/mm spatial frequency. And super thin and compact astigmatic eyeglass lenses are designed. This innovation design is custom design solution.
