Question about Bausch and Lomb Legacy 12-1056 Binocular

1 Answer

For some reason, I get a double vision in my binoculars. I sent them off to be repaired. They were O.K. for three months. Now I have the same problem again. The binoculars have not been dropped or handled roughly. Why did this problem happen again?

Your binoculars either have a bent or broken yoke assembly (the bit which carries the eyepieces) or one or more prisms have came unseated.

The first repair involves replacing the entire yoke assembly: the part is expensive in comparison to the retail cost of a new pair of binoculars and with labour charges on top is not usually a cost-effective repair except on really high end models at prices far higher than yours which can be replaced for under US$110.

The second repair is straightforward and fairly quick for anyone with the right collimation equipment, but the screw(s) need to be secured with thread-locking liquid afterwards.

In this instance, your repair should have lasted longer. Unless a mishap has occurred since repair which has damaged the yoke, you should ask the last repairer to correct their defective work at no extra charge.

I hope you manage to use this information to fix your binoculars or at least that it assists you to choose your next course of action. Please take a moment to rate the free answer I have provided for you and any testimonial which you might wish to add is always welcome!

    How do you get to the prism alignment screws on the unit? It is covered with rubber.

    On most similar models you can carefully peel back the rubber, folding it back over itself.

No apparent exterior damage but now my nikon's have "double vision" clear on each individual tube but doubled vision when veiwing normal. any suggestions?


The prisms have shifted inside of the binoculars. This is not an easy job as you have to make corrections to the angle of the prisms for leaning field and collimation. Two suggestions:
1. If they are under warranty take them to a repair agent.
2. If you want to do it yourself, there are instructions on the web about how to go about effecting a collimation. Too long to go into detail here.

If you have double vision it is out of collimation (alignment of the optical axis). You need to send this to the manufacturer for repair.

Double vision


I'm assuming you have set the dioptre correctly for your eyes.

Normally this is caused by a collimation error when one (or both) prisms move. This can be by a small amount.

Your going to have to take them in for service/repair to fix this as is not a DIY problem. (Unless of course you have a collimator lying around)
