Have you eyes The Sequel
Repetitions are usually good fun to say when speaking. It’s an opportunity to change emphasis, to get a bit of variety in tone, rhythm, timbre, intention. It’s a little trickier when writing a repetition. Especially when they’re so close together.
There are times when it allows a shift in perspective – just like in speech – but I don’t think today is one of those times.
Also, Hamlet is asking a kind of silly rhetorical question. Of course she has eyes. And of course she knows the difference between the two kings and yes she can see whatever it is Hamlet’s pointing to. But hopefully Gertrude judges her partners on more than their outward appearances.
