大细胞系统在视觉运动处理、控制眼球运动和阅读中发挥着重要作用。黄色滤光片可以通过消除对该通路的抑制性蓝色输入来增强大细胞活性。研究发现，佩戴黄色滤光片可以提高许多有阅读困难的儿童的运动敏感性、注意力集中度和调节能力，无论是立即还是使用滤光片三个月后。使用控制中性密度滤光片并没有增加运动灵敏度。此外，与使用安慰剂的儿童相比，阅读障碍儿童在佩戴过滤器三个月后阅读能力显着提高。结论是黄色滤光片可以永久改善大细胞功能。因此，它们应该被视为矫正镜片、棱镜或治疗不良会聚和调节练习的替代品，也可以作为有阅读问题的儿童的辅助手段。
The magnocellular system plays an important role in visual motion processing, controlling vergence eye movements, and in reading. Yellow filters may boost magnocellular activity by eliminating inhibitory blue input to this pathway. It was found that wearing yellow filters increased motion sensitivity, convergence, and accommodation in many children with reading difficulties, both immediately and after three months using the filters. Motion sensitivity was not increased using control neutral density filters. Moreover, reading-impaired children showed significant gains in reading ability after three months wearing the filters compared with those who had used a placebo. It was concluded that yellow filters can improve magnocellular function permanently. Hence, they should be considered as an alternative to corrective lenses, prisms, or exercises for treating poor convergence and accommodation, and also as an aid for children with reading problems.
