Considering the intention of it is "keep the normies from seeing artifact weirdness", it needs to be worn with a specific intent of, among other things, "don't notice me or what I'm doing", it's supposed to enhance whatever the user percieves under the concept of a Masquerade. If, say, Harry Potter were to wear it, he could cast all the spells he wants in a crowded room and none of the Muggles would be able to notice the fact that he's doing magic.
