Color blindness (color vision deficiency) is a disorder that impairs the true perception of colors. Using the information in this study, appropriate policy can be made to identify high-risk groups, as well as educational policies for families to perform more effective genetic diagnosis methods. This study aims to examine the prevalence of color blindness in Iranian students through a meta-analysis. Articles related to color blindness published between January 1990 and December 2020 were searched in Scopus, Cochrane Library, Web of Science (WoS), Science Direct, Embase, SID, MagIran, IranDoc, Medline, and Google Scholar databases. The keywords used were based on medical subject topics (MeSH Terms) and, after careful review, articles were selected according to varied sections of Participants, Exposure, Comparison, and Outcomes (PECO). Participants: students; Exposure: students with color blindness were examined; Comparison: Students from multiple provinces and regions of Iran were surveyed for color blindness; Outcomes: the pooled prevalence of color blindness in Iranian students reported from different provinces. The prevalence of color blindness in Iranian students was 3.8% (95% CI: 2.7-5.4%). The pooled prevalence of color blindness in Iranian male and female students was 4.7% (95% CI: 3.5-6.4%) and 0.7% (95% CI: 0.3-1.3%), respectively. The pooled prevalence of red-green color blindness (Tritan) was 41.7% (95% CI: 18.9-68.8%). The pooled prevalence of red color blindness (Protan) was 13.9% (95% CI: 7.8-23.8%), and the pooled prevalence of green color blindness (Deutan) based on meta-analysis was 45.3% (95% CI: 29-62.7%). Due to the high prevalence of color blindness in students, especially male students, it is necessary to be screened for through genetic tests in couples before having children.
色盲（色觉缺陷）是一种损害对颜色真实感知的病症。利用本研究中的信息，可以制定适当的政策来识别高危群体，以及为家庭制定教育政策，以实施更有效的基因诊断方法。本研究旨在通过荟萃分析来考察伊朗学生中色盲的患病率。在Scopus、Cochrane图书馆、科学引文索引（WoS）、Science Direct、Embase、SID、MagIran、IranDoc、医学期刊数据库（Medline）和谷歌学术数据库中搜索了1990年1月至2020年12月期间发表的与色盲相关的文章。所使用的关键词基于医学主题词表（MeSH术语），经过仔细审查后，根据参与者、暴露因素、对照和结果（PECO）的不同部分选择文章。参与者：学生；暴露因素：对患有色盲的学生进行检查；对照：对伊朗多个省份和地区的学生进行色盲调查；结果：报告的来自不同省份的伊朗学生色盲合并患病率。伊朗学生色盲的患病率为3.8%（95%置信区间：2.7 - 5.4%）。伊朗男、女学生色盲的合并患病率分别为4.7%（95%置信区间：3.5 - 6.4%）和0.7%（95%置信区间：0.3 - 1.3%）。红绿色盲（蓝黄色盲）的合并患病率为41.7%（95%置信区间：18.9 - 68.8%）。红色盲（红色弱）的合并患病率为13.9%（95%置信区间：7.8 - 23.8%），基于荟萃分析的绿色盲（绿色弱）合并患病率为45.3%（95%置信区间：29 -
