They will only work on trichromats (anomalous or normal), and unlike the other types, do not have a significant effect on Dichromats. The glasses do not significantly increase ones ability on colorblind tests. Apps
Many mobile and computer applications have been developed to aid color blind individuals in completing color tasks:

Some applications can identify a color - by name or RGB code - of a color on screen or the color of an object by using the devices camera. Some applications will make images easier to interpret by the colorblind by enhancing color contrast in natural images and/or information graphics. These methods are generally called daltonization algorithms. Some applications can simulate color blindness by applying a filter to an image or screen that reduces the gamut of an image to that of a specific type of color blindness. While they dont directly help colorblind people, they allow those with normal color vision to understand how people with color blindness see the world. Their use can help improve inclusive design by allowing designers to simulate their own images to ensure they are accessible to the colorblind. Epidemiology
Color blindness affects a large number of individuals, with protans and deutans being the most common types. In individuals with Northern European ancestry, as many as 8 percent of men and 0.4 percent of women experience congenital color deficiency.
History
The subsequent studies, following Eduard Glanzmanns  description of hemorrhagic symptoms and "weak platelets" demonstrated that these patients have prolonged bleeding times and their platelets failed to aggregate in response to activation. In the mid-1970s, Nurden and Caen and Phillips and colleagues discovered that thrombasthenic platelets are deficient in integrins  αIIbβ3. See also
