It's sad that this needs to be stated, but literally the only similarity between Old Goggles Lady and Maz Kanata is that they have goggles. But, said goggles are literally completely different in every way other than they ARE goggles.

And even then, one common theory that's going around is that they aren't goggles at all; they're some kind of artificial eyes.
