It's a scientific fact that the best way to see evil aliens who walk among us is through use of magic sunglasses.  John Carpenter's 1988 classic They Live took this fact and ran with it.  But now producer Eric Newman says they might be going in a different direction with the remake.  Speaking at the New York Comic-Con [via io9], Newman said:

Are you going to keep the whole sunglasses aspect to it?

We're discussing that. I'd like to say that really, a vagrant wandering around the streets could get you to try on his sunglasses, if he would leave you alone afterwards. He may even pay you $100, "Hey put these on." So we're kind of exploring different versions of what is that thing that allows you to see. But I'm not going to tell you what it is.

So it might be something different than sunglasses?

It might be something different than sunglasses.

I don't know how you see evil aliens without special sunglasses.  I get the sinking feeling they'll use cell phone cameras or something else that is in no way believable.  However, Newman says the remake isn't going forward until at least next summer and that writer D.B. Weiss is currently busy on HBO's upcoming mini-series, Game of Thrones.  In the mean-time, keep plenty of bubble-gum on hand.
