Color blindness all variations in human color vision involve the red and green receptors in male eyes. It is very rare for males or females to be "blind" to the blue end of the spectrum. The first scientific paper on the subject of color blindness, "Extraordinary facts relating to the vision of colours", was published by the English chemist John Dalton in 1798 after the realization of his own color blindness. Because of Dalton's work, the general condition has been called "daltonism", although in English this term is now used only for deuteranopia. Color codes present particular problems for those with color
Change blindness with a visual cue can help lower the negative effects of change blindness. Stimulation of the superior colliculus improves performance and reaction time in the same way. However, recent research has also been done on countering tactile change blindness. A 2016 study by Riggs et al. shows that three successful methods for limiting tactile change blindness in distinguishing changes in vibration patterns are attention guidance, signal gradation and direct comparison. All three methods seek to bring attention to the area of change. Attention guidance works proactively by increasing the frequency of a cue. The second and third methods are reactive
