Eye distance
The distance between one's eyes varies
from person to person, so it is essential
that you adjust your binoculars before
you use them. Take the binoculars in both
hands (Fig. 1) and hold them to your eyes.
Fold them so that you see a single circle
when looking through them with both
eyes (Fig. 2).
Adjusting the focus
Find an object over ten metres away.
Close your right eye, or hold a finger over
it. Turn the focusing wheel (Fig. 3) to fo-
cus correctly for your left eye. Then repeat
the process with your other eye using the
dioptre adjustment (Fig. 4, 6). Once you
have both focused correctly, you'll be able
to see any object in focus with both eyes.
If you wear glasses
The eyepieces on the lenses fold (7). Fold
them back if you wear glasses to see in
focus (Fig. 5).
