The distance between the eyes,called"interpupillary distance" varies from person to person, To achieve 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 futher apart until you see a single circular field.Always re-set your binoculars to this position before using, Most binoculars have graduated area at eht top of the center hinge for reference in sunsequent use in setting interpupillary distance.
Diopter setting and central focusing
1.Set right eyepice(A) to zero and sight on a distant object
2.Cover right objective (front)lens with your hand, then rotate central focusing wheel(B) until the image in the left eyepiece is sharp. Keep both eyes open while making this adjustment.
3.Cover left objective(front) lens with your hand then rotate the right eye-piece until the image is sharp again.
4.Image should now be focused to your eyestrength .
Note diopter setting for future reference.
Roll down eyecups
