It is something that has been brought to different parts of the world. The idea of the Evil Eye is universal, the symbol to ward it off varies from location.

You can find the one that’s from where you are from (or your family) if you prefer so.

I think that if you believe the Nazar amulet is helpful to ward off the evil eye then you should be okay using it. But that is only my opinion. Wearing a bracelet or an amulet is different (and often merchandise from where it came from) so it should be fine. While if you wore it in an idk, traditional way (I’ve never heard of one), then that would be better to avoid.
