(2) Methods: study participant colour vision was assessed with anomaloscope, HRR, FM100 hue, and CAD tests. (3) Results: No significant correlation was found between participant age and chromatic sensitivity of the red\u2013green colour opponent channel. However, a decrease in blue\u2013yellow colour opponent channel chromatic sensitivity was confirmed with the FM100 hue test and CAD test. Analysis of FM100 hue test error scores across age groups revealed a decline in chromatic sensitivity in the short-wave region of visible light with increasing age. Comparison of the colour-deficient individual results of the CAD and anomaloscope tests confirmed that CAD test sensitivity and specificity reaches 100%. However, some individuals with deutan-type deficits were misclassified as having protan-type deficits. This study confirmed the effectiveness of the FM100 test in identifying individuals with moderate to severe colour vision deficits, with sensitivity and specificity rates of 81.25% and 95.38%. (4) Conclusions: It was found that the FM100 hue test effectively identifies individuals with moderate and severe red\u2013green colour vision deficiencies. On the other hand, individuals with mild colour vision deficiencies may go undetected with the FM100 hue test.<\/jats:p>","DOI":"10.3390\/vision8030053","type":"journal-article","created":{"date-parts":[[2024,9,6]],"date-time":"2024-09-06T06:18:35Z","timestamp":1725603515000},"page":"53","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Colour Vision Changes across Lifespan: Insights from FM100 and CAD Tests"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5694-0614","authenticated-orcid":false,"given":"Ren\u0101rs","family":"Truk\u0161a","sequence":"first","affiliation":[{"name":"Department of Optometry and Vision Science, Faculty of Science and Technology, University of Latvia, LV-1004 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergejs","family":"Fomins","sequence":"additional","affiliation":[{"name":"Institute of Solid-State Physics, University of Latvia, LV-1063 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6596-3364","authenticated-orcid":false,"given":"Zane","family":"Jansone-Langina","sequence":"additional","affiliation":[{"name":"Department of Optometry and Vision Science, Faculty of Science and Technology, University of Latvia, LV-1004 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Tenisa","sequence":"additional","affiliation":[{"name":"Department of Optometry and Vision Science, Faculty of Science and Technology, University of Latvia, LV-1004 Riga, Latvia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"313","DOI":"10.1364\/JOSAA.29.000313","article-title":"Worldwide prevalence of red-green color deficiency","volume":"29","author":"Birch","year":"2012","journal-title":"J.
