I've never seen the benefit of wearing sunglasses to a poker table. Then again, in my personal case I don't really think I have as many eye-related
tells as some might, because I have this thing where even when my eyes are open they don't look...fully open, if that makes sense? Like, they look sort of half closed all the time. Not very accessible windows to the soul, those.
And personally, in live situations I've started to be able to get a lot more tells from people's
hands than their faces. So if I sat down with someone in shades I'd just make even more of a point of looking at their hands.
