I dont know how it is in other fields, but in physics, at least, reviews are only singly blind. The reviewer knows who the author is. Even then, it is often possible to guess at the referrer based on the comments they make. Blinding the author would be nearly impossible due to the small number of workers on most specific topics. That being said, I'm not sure why journals don't at least try (which should benefit newcomers to an area).
