They play an important part in
creating the unique STEINER view-
ing experience. As twist-up / twist-
down eyecups they easily adapt
to your individual preferences,
whether you wear glasses or not.
eyeglass wearers
Wearing glasses you have already
created the necessary distance be-
tween the binoculars’ oculars and your eyes. Contrary to
users without glasses (or with contact lenses) you usually
don't need to artificially create this distance and you can
use your binoculars with both eyecups fully retracted.
To retract the eyecups simply use your thumb and index
finger to twist them in the direction indicated by the
arrows. Then fold down the sidelight screen. When
looking through your binoculars you can put your glasses
directly onto the eyecups - the soft silicone material
prevents scratching.
