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 barrels closer together or further apart until you see a singular circular field. Always reset your binoculars to this position before using. 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 eyepeice 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. twist-adjust eyecups adjustable right diopter (eyepiece) ed ÿeld of view. central focusing wheel
