best goggle lens?

Tweet

Since I got a gym membership I want to get some goggles so I can go swimming. I used to just have ones that were tinted bue way back when because that's all they really had. I'm out to get a new pair so I can swim. However, I don't know what's best for indoors clear, blue, black/grey or silver lens. Though the silver was supposed to reduce glare in the water perhaps?
