The sensitivity of the blue cone system to low frequency flicker was tested with a psychophysical and an electroretinographical method. With the psychophysical method the subjects, members of a family with an inherited tritan defect, showed no sign of the presence of the blue cone system. With the electroretinogram the sensitivity was also significantly lower than in normal subjects, thus indicating a retinal origin of the tritan defect.
采用心理物理学和视网膜电图描记法测试了蓝锥系统对低频闪烁的敏感性。通过心理物理学方法，对一个患有遗传性蓝色色盲缺陷的家族成员进行测试，结果显示没有蓝锥系统存在的迹象。通过视网膜电图也发现，其敏感性显著低于正常受试者，从而表明蓝色色盲缺陷起源于视网膜。
