"The rabbits' eye differs from that of the owl."
This saying is basically about how the eyes of one person differ
from the eyes of another. Just as the eyes of the owl differ from
those of the rabbit.
Two persons may see the same event and recount two different
stories as to what occurred. In this situation a person may say this
saying commenting how they knew how the event really occurred as their eyes
are sharper than the other person's, just like the way the owl's eyes are
sharper then the rabbits.
