The Farnsworth-Munsell (FM) 100-hue test is well known but is also time consuming, especially its analytical component. To reduce this needless time-waste during precious working hours, a simple modification was devised.
Prospective, comparative, observational study.
A transparent clear plastic carrier box replaced the opaque one, allowing ready digital photodocumentation of top and bottom without even opening the box, or handling/inverting the caps -200 reportedly normals and 50 known color vision defectives could be easily tested on this modified-FM and results stored, allowing rapid turnover. The captured scores with patient ID were analyzed, at leisure, outside hospital time, saving 45-60 minutes/patient. After recording, the box was promptly handed over to the next subject for rearrangement. Times taken for test/patient were recorded.
Running time was reduced from 60-75 min to 15 min/patient with no waste of invaluable lab hours. Turnover time is limited to capturing two photographs (60 sec). The box is relatively cheap and easy to maintain.
Our simplified FM 100-hue test allowed rapid assessment of color visions with easy data storage of both top and bottom.
法恩斯沃思-芒塞尔（FM）100色调试验广为人知，但也很耗时，尤其是其分析部分。为了在宝贵的工作时间内减少这种不必要的时间浪费，我们设计了一种简单的改进方法。
前瞻性、对比性、观察性研究。
用一个透明的塑料载盒取代了不透明的载盒，这样甚至无需打开盒子，也无需操作或翻转瓶盖，就能对顶部和底部进行即时数码拍照记录。据报道，使用这种改良后的FM试验，可以轻松对200名正常人和50名已知色觉缺陷者进行测试，并存储结果，实现快速周转。在医院外闲暇时间，对带有患者ID的捕获分数进行分析，每位患者节省45至60分钟。记录完成后，立即将盒子交给下一位受试者重新安排。记录每位患者的测试时间。
每位患者的运行时间从60至75分钟减少至约15分钟，且宝贵的实验室时间没有浪费。周转时间仅限于拍摄两张照片（约60秒）。该盒子相对便宜且易于维护。
我们简化的FM 100色调试验能够快速评估色觉，并能方便地存储顶部和底部的数据。
