Your Carson 3D binoculars
feature a roof prism system.
The prisms overlap closely
allowing the objective
(front) lenses to line up
directly with the eyepieces.
The result is a slim,
streamlined shape in which
the lenses and prisms that
magnify and correct the
image are in a straight line.

The distance between the eyes, called “interpupillary distance,” varies from person to person. To achieve perfect alignment
of lens to eye, follow these simple steps:
t alignmen o ey w these simple steps:
1. Hold your binoculars in the normal viewing position.
2. Grasp each barrel firmly. Move barrels closer together or further
apart until you see a singular circular field. Always reset your binoculars
to this position before using.
ED GLASS
Your Carson 3D-ED binoculars contain ED Glass (extra low dispersion glass) in their lenses. This ED Glass helps prevent
chromatic aberration (fringes of color that appear around the viewing image).
FOCUSING YOUR BINOCULARS:
Carson 3D binoculars have a center focus wheel and an
independent right diopter eyepiece to account for small
differences in the strength of each eye. Please follow the
steps below to focus properly:
1. Adjust the interpupillar distance.
2. Rotate the right eyepiece to its index mark and
sight on a fixed distant object.
3. Cover the right objective (front) lens with your
hand, then rotate the central focusing wheel until
the image in the left eyepiece is sharp.
4. Cover the left objective (front) lens with your
hand then rotate the right eyepiece until the
image is sharp. (Note this setting for future use.)
5. Image should now be focused to your individual
eyestrength.
TWIST-UP EYECUPS:
Your Carson 3D binocular features twist-up eyecups
designed to exclude extraneous light. If you do not wear
eyeglasses, you may choose to twist the eyecups out to
block stray light and reflections from your view. If you are
an eyeglass wearer, lowering the eyecups will bring your
eyes closer to the binocular lenses, providing an improved
field of view.
