本文通过对当今眼镜市场上传统产品的比较及配戴使用效果的分析，结合眼睛的调节与适应原理，引出一传统消费的误区，提出了一种眼镜消费的新空间即双焦镜片的应用开发。本文概述了双焦镜片设计的基本原理，并对符合眼睛调节的双焦镜片片形设计、光度调节以及像差理论进行了论证。结论是：双焦镜片可解决中老年眼疾患者看远近物体时需配戴两副不同光焦度眼镜的痛苦；双焦镜片同样适用于年轻人，可缓解眼睛的调节疲劳，防止度数的上升。充分开发双焦镜片的功能，对于卫生用眼，后天防治眼疾有着重要意义。 Based on the comparison of the traditional products on the market of glasses and the analysis of the effect of wearing and using, combined with the regulation and adaptation principle of the eyes, this paper leads to a misunderstanding of traditional consumption and proposes a new space for the consumption of glasses, namely, the application and development of bifocal lenses . This article outlines the basic principles of bifocal lens design and demonstrates the sheet-shaped design, the photometric adjustment, and the aberration theory of the bifocal lens that is in line with the eye’s adjustment. The conclusion is: Bifocal lenses can solve the pain of elderly patients with eye diseases need to wear two pairs of glasses with different optical powers when looking at objects in the near and far. Bifocal lenses are also suitable for young people, which can relieve eye fatigue and prevent the degree increase. The full development of the function of dual focal lenses for eye health, acquired control of eye disease is of great significance.
