Special filters in glasses could help the colorblind see colors better, according to new research from the UC Davis Eye Center and France’s INSERM Stem Cell and Brain Research Institute.
The much-touted EnChroma glasses don't help colorblind users see new colors; they merely let the colorblind see the same colors in a different way, according to a new study published in Optics Express by scientists at Spain's University of Granada.EnChroma makes glasses that are designed to help with a specific form of color blindness, one in which a hybrid of red- and green-detecting receptors confuse the differences between colors.So the new results don't come as a surprise to University of Washington color-vision expert Jay Neitz, who has long been skeptical about what the glasses actually accomplish.But EnChroma CEO Andrew Schmeder takes issue with the study's conclusions.Writing in The Atlantic in 2015, he said "It's not like they were worse than regular sunglasses—there was a way in which certain things popped out—but not in the way that it felt like it was advertised."He was not blown away when he donned them, unlike many of the people in the company's testimonial videos.
