Your eyes can see a range of colors from 380nm and 760nm. That is, we can tell the difference between two different wavelengths when they’re both in that range. Some colorblind people are missing 1 of 3 color cones and can’t tell the difference between red(700nm) and green(520nm), but they can still see the colors between blue(470nm) and green(520nm).
The glasses take all the light that blends together for them, and squishes it down into the range that they can tell the colors apart. They don’t see any colors they couldn’t see before, but all the details that were hidden from them now suddenly pop out.
