In the last 2 decades, there has been a resurgence of the idea that passive aids such as colour filters can be an effective solution to compensate colour vision deficiency (CVD) or improve colour vision for subjects with CVD. We examine briefly the scientific evidence that has to date been gathered to study the reliability of these aids. In the light of our experience working in this field, we reflect on several related issues: why this question has not been elucidated before, how a filter would have to be designed for a specific task, and the importance of developing a personalised colour space for subjects with CVD to gain some insight into the effect of aids.

真的有可能用滤镜补偿色盲吗？

在过去的20年中，人们重新流行这样一种观念：被动式辅助设备（例如滤色镜）可以作为补偿色觉不足（CVD）或改善患有CVD的受试者的色觉的有效解决方案。我们简要地检查了迄今为研究这些辅助工具的可靠性而收集的科学证据。根据我们在该领域的工作经验，我们思考几个相关的问题：为什么以前没有阐明这个问题，如何为特定的任务设计滤镜，以及开发个性化色彩空间的重要性。患有CVD的受试者可以深入了解辅助工具的效果。
