In 2018, a study of EnChroma lenses showed that they help color blind people to see the same colors in a different way since the colored filter altered the way colors appeared in their eyes. The researchers found the effect of using EnChroma glasses is similar to glasses where the use of color filters changes the user's perception and increases the contrast among the colors, such as those used for shooting or hunting. The research showed that EnChroma glasses did not reveal any improvement in the Ishihara test and Farnsworth–Munsell 100 hue test.
