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.
That is, either the spectral sensitivity of the L cone shifts towards the M cone (blue shift), or that of the M cone shifts towards the L cone (red shift). These are then called anomalous cones and denoted by an asterisk (L* or M*). Since the mutated OPN1LW and OPN1MW genes are on the X chromosome, they are sex-linked, and therefore affected males and females disproportionately. Because the colorblind alleles are recessive, colorblindness follows X-linked recessive inheritance. Males have only one X chromosome (XY), and females have two (XX); Because the male only has one allele of each gene, if it is mutated, the male will be colorblind. Because a female has two alleles of each gene (one on each chromosome), if only one allele is mutated, the dominant normal alleles will "override" the mutated, recessive allele and the female will have normal color vision. However, if the female has two mutated alleles, she will still be colorblind. This is why there is a disproportionate prevalence of colorblindness, with ~8% of males exhibiting colorblindness and ~0.5% of females (0.08² = 0.0064 = 0.64%). The following table shows the possible allele/chromosome combinations and how their interactions will manifest in an individual. The exact phenotype of some of the combinations depend on whether the mutation yields an anomalous or non-functioning opsin. Blue cone monochromacy also follows these inheritance patterns, since it essentially a superposition of protanopia and deuteranopia. Y
