I was gifted a pair of enchromas, and while they don't make me see "new" colors, it's undeniable to me that they allow me to distinguish between some colors that I previously could not.
For example, light pinks always flatten out to grey for me. Wearing the glasses lets me distinguish between grey and pink. Likewise, I can see the fall colors in trees and can point out which ones are red/orange/green/yellow whereas I could not before.
So yes, they are deceptively marketed and probably not worth the money. But they do, in fact, have some utility.
This is accurate. Most likely you have a mild form of CVD, where some of the cones in your eyes overlap in their light frequency response. This makes it hard to distinguish colours containing that frequency range, because multiple cones respond to them when only one should.
The glasses actually work by completely blocking out the light in those overlapping frequency ranges. This will help to avoid the confusion between the cones, and could help you better distinguish colours containing components in those ranges. That's also why the glasses have this pink hue in the video. By removing some colours from white light, the remaining ones combine into pink-ish light.
Obviously, you cannot restore normal colour vision by blocking out even more colours. The marketing from enchroma is pretty scummy.
It sucks that their marketing is shitty, because what they actually do seems pretty clever. I have a pair of enchromas and I enjoy them for what they are - being able to distinguish color differences when I can't normally is fun.
It's an overpriced novel experience, probably not worth it but cool if you can afford it.
Shitty, but also really clever in terms of marketing. "Helping people with colour blindness more easily distinguish between certain colours whose wavelengths overlap (but are distinct to those without colour blindness)" is accurate, but not as exciting (or as easily understandable) as "FIXES COLOUR BLINDNESS".
Fair, I honestly don't know how else you explain that to most people concisely.
