建立老花眼球光學系統模擬配戴單焦與多焦的矽水膠隱形眼鏡之視覺表現探討

本研究以Zemax軟體建立人眼光學模型，並在眼球模型上附加隱形眼鏡，探討老花眼球配戴矽水膠材質之單焦與多焦點隱形眼鏡的在視覺的表現。眼球生理隨老化改變，且性別、人種也有差異，本研究以40歲女性白人的初期老花參數作為老花眼球模型設計參考。研究將隱形眼鏡的鏡片前表面以不同屈光度設計成同心圓屈光變化的多焦型式，隱形眼鏡模型的屈光設計參數以酷柏珂朗清日拋隱形眼鏡的規格為參考依據最後將探討老花。人眼模型附加單焦與多焦隱形眼鏡後，模擬眼球系統在各種不同工作距離與環境光亮度下所得到的視覺表現。

In this study, Zemax software was used to build an optical model of the human eye, and contact lenses were added to the eyeball model to explore the visual performance of the presbyopia of unifocal and multifocal contact lenses made of silicone. The physiology of the eyeball changes with aging, and there are also differences in gender and race. This study uses the initial presbyopia parameters of a 40-year-old white female as a reference for the design of the presbyopia eyeball model. In the study, the front surface of the contact lens was designed with different refractive powers into a multifocal type with concentric refractive changes. The refractive design parameters of the contact lens model were based on the specifications of the CooperVision clariti daily contact lenses. Finally, we will discuss the presbyopia with the addition of unifocal and multifocal contact lenses to the human eye model, the visual performance of the eyeball system under various working distances and ambient brightness is simulated.
