摘要

本文研究目的係使用非球面及重量最佳化設計一精巧型高度近視眼鏡。設計時著重客製化眼鏡設計以適合高度近視眼睛病患的配戴，設計當中並進一步對遠、中、近視場進行優化，使眼鏡也適合看遠、中、近距離。本精巧型高度近視眼鏡除了可矯正高度近視(-8.00D)之外，還可以使配戴－8.00D眼鏡之後的眼睛解像率在301p/mm的MTF值達0.3。經重量最佳化設計之後，還可以使高度近視眼鏡的邊緣厚度從6.16mm降至3.98mm。

This paper studies the design of the aspheric high power myopic ophthalmic lens by the aspheric surface and the optimizing mass of lens for the minimum edge thickness. The design of myopic ophthalmic lens has considered the effects of myopic eyes and three configurations, named far, middle, and near view fields according to visual action of the human eye. These three configurations have three different view angles for the eye. We have designed a -8.00D aspheric eyeglass lens to correct the myopia. The MTF values have more than 0.3 when spatial frequency is 30lp/mm.The edge thickness of the lens reduces from 6.16mm to 3.98mm by using this novel technology.
