l
Pupil distance
The purpose of this adjustment is to align the exit pupils of the binocular
with the pupils of your eyes. If they are not correctly aligned, you will
experience discomfort from having to use only one eye. Whilst looking at a
distant object, carefully move the binocular tubes downward or upward so
that both fields are correctly aligned, forming a perfect circle.
