Tritan (blue-green) colour vision disturbances have been found in 79 individuals in six families, revealing an autosomal dominant mode of inheritance with a wide variability of test results within families. Evidence is presented that it is--in contradistinction to the X-chromosomally inherited red-green defects--incorrect to make a subdivision between dichromasia (tritanopia) and anomalous trichromasia (tritanomaly). On the basis of three small screening series, totalling 1900 individuals, the frequency of tritan disturbances is estimated to be around 2 per 1000. Seven males have been observed carrying both inherited tritan and red-green defects.
在六个家族的79个人中发现了蓝绿色（ Tritan ）色觉障碍，揭示了常染色体显性遗传模式，家族内测试结果差异很大。有证据表明，与X染色体遗传的红绿色缺陷不同，将二色视（蓝色盲）和异常三色视（蓝色异常）进行细分是不正确的。基于三个总计1900人的小型筛查系列，估计蓝色觉障碍的发生率约为每1000人中有2例。观察到7名男性同时携带遗传性蓝色觉和红绿色觉缺陷。
