Prism System
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.
Eye Adjustments
How to adjust for distance between your eyes: 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:
1. Hold your binoculars in the normal viewing position
2. Grasp each barrel firmly. Move the barrels closer together
or farther apart until you see a single circular field.
Always reset your binoculars to this position before using.
