One claim on the company's website (at least until October 2017) was that their glasses "are designed to improve the everyday experience of color vision." However, that claim was recently changed to a more subtle statement: "The glasses are an optical assistive device for enhancement of color discrimination in persons with color blindness; they are not a cure for color blindness," it says, pointing out that "results vary depending on the type and extent of color vision deficiency per individual."

In an article published in Optics Express, researchers from the University of Granada (UGR) have debunked the effectiveness of these glasses for color vision deficiency (CVD), proving that the EnChroma glasses don't make color blind people's vision comparable to that of people without color blindness.
