It’s not just the eyes, it’s both. I can fuck up your vision through drugs, none of which actually affects the physiology in your eyes.
The brain is the one that transmogrifies the light and reassembles your world. Remember that the eyes see upside and in reverse. It’s the brain that puts it all together. And that processing matters.
The tl;dr is that this is complex. And glasses can’t help you. Even if you somehow fixed your cones to see colour, your brain would still be left in the dark. It’s… complicated. More complicated than putting a film over your eyes.
It’s a scam. And they probably have a long legal disclaimer that protects from simply “doing nothing.”

What they can do is block certain light that overlaps in some of your rods and cones (colorblind) in your eyes allowing you to distinguish between colors you previously could not.
Not magic. Just pyshics. They do not fix the issue but it gives your brain new information that was previously obscured. Then your brain can use this info to distinguish between the two overlapping wavelengths that you previously could not.
