If you do, you may cast it without components (though the eye's transformation makes it obvious you're casting a spell) and as if cast from a spell slot one level higher. As long as your evil eye is showing, you may concentrate on other spells or effects while maintaining concentration on hex. If your concentration is broken, it is broken for all things you are concentrating on at once.



Also added +1 spell slot level, basically allowing somebody investing in an invocation for hex to get 8 hours out of it at level 3. I consider the further upgrade at a higher level to 24 hours to be a much less significant jump, even though it definitely has utility.
I probably wouldn't increase the spell level by 1, and I probably would add a level requirement of Warlock 5, but overall I think the concept is fine (the level requirement helps deter multiclass shenanigans).

There's nothing in Hex's description that placing of the curse is noticeable in any way.
The is an awful argument. Here's why:
"Because that's how 5e spells work. If a subsequent action granted by the spell is supposed to be undetectable, it must be somehow indicated in the spell's description."
"There's nothing in Hex's description that placing of the curse is not-noticeable in any way."

2 letters for the first argument, 3 letters and a dash for the second, and they make the opposite case you are trying to make. And what really sucks is all 4 sentences are technically accurate. The spell description doesn't say anything one way or the other. So it's down to ruling and making inferences.
