Binoculars are an optical device with a fairly accurate setting. Therefore, falls and sharp blows are contraindicated for him. Even in the presence of a rubberized casing, such treatment can cause a discrepancy in the optical axes of both pipes and, as a result, ghosting of the picture. What to do if something like this did happen?

Screwdriver, blade
Instructions
Step 1
We open a secret - in the overwhelming majority of cases, everything is fixable. You can correct the misalignment on your own. The main thing is to act carefully, otherwise you can further aggravate the situation. With careful handling, it will not be difficult to fix the problem.
Step 2
If you have binoculars with Porro prisms (tubes with a characteristic kink), then in 9 cases out of 10, in case of misalignment, one of the objectives should be rotated around the axis, which specially have a slight displacement of the thread relative to the optical axis. When making adjustments, visually check the clarity of the image each time.
Step 3
Binoculars of another common type - with “roofed” prisms, which differ in straight tubes, have special screws that hold the prism unit in the desired position. By rotating these screws with a clock screwdriver or a suitable blade, you can shift the axis of one of the pipes until the images are aligned with the other.
Step 4
Theatrical binoculars (without prisms and with a diffusing eyepiece) are less sensitive to shocks due to their low magnification, but if necessary, they are repaired in the same way. And, to which you should pay special attention, you should not try to eliminate double vision by forcefully moving the pipes themselves - with a high probability you will break them.
