These sunglasses (that come in multiple styles/models) allow people that have color vision deficiency to see in full hues. Of course, there are multiple types of color blindness, but the sunglasses are effective for most people with color blindness to see. Color blindness definitely affects every day life by being unable to differentiate between colors, which come up more often in our lives than I think we initially realize: traffic lights, meat cooked all the way, picking out clothes, etc.
