The more you play, the less you look at it.
As others have noted, you will sometimes find yourself double checking it just to make sure you actually have the hand your brain is telling you that you have.
Its no different than people playing holdem for the first time have to use that little "possible hands" card when they first start, or a blackjack strategy card. Eventually you just get so use to reading the board, that you don't even give hand reading a second thought. Unless checking that you do in fact have a monster in the face of a shove lol
