Congratulations on selecting your new Carson binoculars!
With reasonable care,your binoculars will provide you with years of enjoyment.
In order to achieve optimum performance,please read the instructions
carefully on the proper use and care of your binoculars.
Instructions for Care
Like any fine optical instrument,your binoculars should be
given sensible care. Keep the lens covers (not included with
some models) on the lenses when binoculars are not in use.
Do not drop or violently jar your binoculars. This may cause the internal
optical components of your binoculars to become misaligned resulting
in a double image when looking through them.Non-waterproof models
should not be exposed to excessive moisture.

Magnification: Typically binoculars range from 5x to 12x power. A 5x binocular means that the image you see through the binocular is 5 times larger than it would be when viewed with the naked eye. instructions_8page.indd 2...
- Page 3 358’wide and a thousand yards away will take up the entire viewing area of the binocular image you see. Sometimes this measurement is listed in degrees and is referred to as Angle of View,i.e. 8°. To convert to feet,multiply the number of degrees by 52.5 and you will get the FOV.
- Page 4 Binoculars come in two distinct styles in which design is dependent upon the type of prism system used. The image that passes through a binocular is upside down (a function of the lens) and needs to be corrected. This prism is the optical glass inside a binocular whose purpose is to“invert”the image.

Page 5: Eye Adjustments
Porro Prism Systems: the objective lens is offset from the eyepiece. Light is redirected through the binocular internally. The result is a shorter,stockier shaped binocular. In general, porro prism binoculars offer a wider field of view. Most zoom binoculars use the porro prism system for this reason. - Page 6 Focusing your binoculars: Most 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 interpupillary distance. 2.
- Page 7 Others will not have a center focus wheel,and you must turn each eyepiece independently to focus. Never try and force an eyepiece if it was not designed to turn. This may seriously damage your binocular. Roll-Down Eyecups Your binoculars may be fitted with rubber eyecups designed to exclude extraneous light. If you wear eyeglasses,you may be able to roll-down the eyecups.
