There's an ambiguity here. On one hand, vision involves processes taking place in the eyes and the optic nerves that involve light. On the other hand, vision involves processes taking place in the occipital lobes that construct spatial imagery and don't directly involve light. Dark vision seems to be the latter without the former.
