Is It "eye Cup"?

[AlvinMac]

"I reportedly have drinking vessel used for bathing in North America."
I suppose that the answer is "eye cup" but I can't quite see the North America connection! Or am I missing an alternative answer??

Eyecup ("I cup") - an American eyebath

Americans call an 'Eye Bath' an 'Eye Cup' - so it may well be the answer.

Ah, thank you so much. I was beginning to think it might be something to do with the fact that the metal baths used by cowboys in the old westerns seemed to be shaped like gigantic eyebaths!
