Oh, I forgot to mention your comment on excellent eyesight. Deer have very low visual acuity, in fact from a few yards away, they cannot distinguish leaves on a bush. Dr. Gino D'Angelo and colleagues (I have taken a course in which Gino presented results on deer senses) studied deer vision using test similar to a vision chart in human except using black bars of different sizes. They concluded that deer have about 80% less visual acuity than humans, the equivalent of 20/100 distance vision. Analysis of the anatomy of the deer eye further supports that it is incapable of providing a high degree of acuity. LINK

Deer do collect more light in their eyes than humans do and so can see shapes better at night than we can but they still have very poor vision in terms of acuity.

In contrast, they have excellent motion detection capabilities, which is what I think you were trying to convey. They also have very good peripheral vision, but again, this mainly aids them in motion detection.
