Abstract

This study aims to investigate the potential impact of commercial low-vision filters on intrinsically photosensitive retinal ganglion cells (ipRGCs), which have significantly advanced our understanding of non-image-forming visual functions. A comprehensive analysis by modeling the potential responses of ipRGCs to commercially available low-vision filters was conducted, focusing on how the spectral properties of these filters could alter ipRGC function. Additionally, the influence of aging on the crystalline lens was considered. Colorimetric changes in the transmitted light by these filters were also analyzed, highlighting variations based on the manufacturer. The study uncovered the diverse responses of ipRGCs to fifty low-vision filters, shedding light on the potential modifications in ipRGC stimulation and visual function. Notably, the consideration of aging in the crystalline lens revealed significant alterations in ipRGC response. Furthermore, the analysis of colorimetric changes demonstrated substantial differences in the light transmitted by these filters, with variations dependent on the manufacturer. This research underscores the nuanced relationship between low-vision filters and ipRGCs, providing insights into their potential impact on visual function. The varying responses observed, coupled with the influence of aging on the crystalline lens, emphasize the complexity of this interaction. Additionally, the distinct colorimetric changes based on filter manufacturer suggest the need for tailored approaches in enhancing visual perception for individuals with visual impairments.

摘要

本研究旨在调查商用低视力滤光片对内在光敏性视网膜神经节细胞(ipRGCs)的潜在影响,这极大地推进了我们对非成像视觉功能的理解。通过对ipRGCs对市售低视力滤光片的潜在反应进行建模,开展了全面分析,重点关注这些滤光片的光谱特性如何改变ipRGC功能。此外,还考虑了衰老对晶状体的影响。还分析了这些滤光片透射光的比色变化,突出了基于制造商的差异。该研究揭示了ipRGCs对五十种低视力滤光片的不同反应,为ipRGC刺激和视觉功能的潜在改变提供了线索。值得注意的是,对晶状体衰老的考虑揭示了ipRGC反应的显著变化。此外,比色变化分析表明这些滤光片透射的光存在很大差异,其变化取决于制造商。这项研究强调了低视力滤光片与ipRGCs之间的细微关系,为它们对视觉功能的潜在影响提供了见解。观察到的不同反应,加上衰老对晶状体的影响,强调了这种相互作用的复杂性。此外,基于滤光片制造商的明显比色变化表明,需要采用量身定制的方法来增强视力受损者的视觉感知。
