There is no standard height for a door viewer. The door viewer should be positioned so that the majority of people can use it, which will mean low enough to accommodate a majority of short people, because taller people can bend down to use it.
While this may be inconvenient for taller people, they can at least use it, whereas short people would need to use a step, which would be extremely inconvenient.
Other factors are the likely users. If there are likely to be wheelchair users or very short people it may be best to have two viewers.
Note that the viewer needs to be set for eye height, not head height.
