Adjusting
for
interpupillary
distance
In order to see one singular image,
you must adjust the two barrels
of the binoculars to your
interpupillary distance (the distance
from your left pupil to right).
To do this, turn the barrels of the
binoculars on their central hinge
until you see one singular field of
view with no disturbing shadows.
Focusing
your
binoculars
The Vortex Razor features a large center focus knob, with the
diopter adjustment integrated inside the focus knob. The diopter
adjusts for differences between your individual eyes. The correct
procedure for attaining proper focal balance using the center
focus knob and the diopter is:
a. Adjust the binocular barrels for your interpupillary
distance (see above).
b. With your right eye closed (or with your hand over the
right objective lens), focus your left eye on a distant object
with the center focus wheel until the targeted object is in
sharp focus.
c. Now adjust for your right eye. To do this, pull on the
focus knob until you hear an audible click - the focus wheel
is now adjusting the diopter. Close your left eye (or place
your hand over the left objective lens) and focus your right
eye on that same distant object. Focus until the object is in
sharply focused. Your binoculars should now be adjusted to
provide a clear and comfortable image.

below). If you do NOT have
the eyecups positioned correctly, you will note black
"crescents" in your field of view.
Using
the
flared
eyecups
The Razor features inventive flared
rubber eyecups that can be easily
interchanged with the retractable
eyecups. The flared eyecups, which
are not retractable and are meant
to be used only in the “up” position
as shown at right, are useful in
eliminating bothersome lateral light.
To install the eyecups:
1. Remove the retractable eyecups. Twist each eyecup
to the “QR” position and firmly (but easily) pull each
one off the binocular.
2. Place the flared eyecup onto the binocular and line the
QR arrows with the dot on the binocular body (inset image
above). Twist the flared eyecup to lock it into position.
The flare of the eyecup should fit comfortably on the outside
edges of your eyes; adjust the eyecups to the best fit.
