The eye may receive 10 million bits per second, and the optic nerve and brain do a marvellous job of finding patterns in those 10 million bits, but that doesn't mean we're processing it efficiently.
As Eliezer pointed out, an "Efficient" processing would allow us to derive the theory of relativity (or at least Newtonian mechanics) from about 6 frames of an apple falling in a field. That would be a super-efficient use of available information, but not even the best possible use! The eye might be a fantastic piece of kit, but it sure as hell doesn't do that. (or if it does, I need a proper user's manual, cause I haven't figured out how to do it yet!)
