摘要
综述渐进多焦点眼镜片的设计方法,旨在阐明渐进多焦点眼镜片设计技术的现状以及发展方向。首先介绍了渐进多焦点眼镜片的基本设计原理,随后深入探讨了三种主要的设计方法:直接设计方法、间接设计方法和梯度折射率设计方法。尽管这些方法在提升镜片光学性能和满足个性化需求方面取得了显著成果,但仍存在设计复杂、制造成本高和材料特性依赖等局限性。最后,强调了计算机辅助设计和制造技术在渐进多焦点眼镜片设计和制备中的重要意义,并指明了未来研究方向。
This paper reviews the design methods of progressive addition lenses to address the increasing number of presbyopic patients in the context of the global aging trend.The paper first introduces the basic design principles of progressive addition lenses,including their four functional zones:the distance vision zone,the near vision zone,the gradual transition channel,and the peripheral astigmatism zone.The paper then discusses three main design methods in detail:the direct design method,the indirect design method,and the gradient refractive index design method.The direct design method achieves continuous multifocal variation by precisely controlling the geometry and curvature changes of the lens;the indirect design method designs customized progressive addition lenses by minimizing an optimization function;the gradient refractive index design method utilizes the gradual change in refractive index of the material to achieve increasing optical power.The paper notes that,while these methods have made significant progress in improving optical performance and meeting individualized needs,they are limited by design complexity,manufacturing cost,and material properties.Finally,the paper emphasizes the importance of computer-aided design and manufacturing technology in optimizing design methods and improving production efficiency,and suggests directions for future research to meet the ever-changing needs of visual health.
