Sunglasses for golf
Does anyone know, with some authority, whether the sunglasses you wear for golf should be polarized or not? I read that polarized glasses may hamper your ability to read putts. Not sure why that's true if it is. Also, are there certain tints of sunglasses that we should or should not use? Just looking for a couple pair of sunglasses for eye/sun protection, but don't want to spend the money for the wrong ones.
