I have a pair of Bushnell 20x50 Powerview getting double vision. Can focus each side by themsleves but not together.


Sorry to say but it sounds as if the binoculars have suffered a jolt.

All bincoculars are collimated at the factory so they will focus together at a "central point".

Some Binocular dealers will check the collimnation prior to shipping.. and make adjustments as needed..

If the internal prisms were shifted out of place or the frame was bent.. chances are it will be cheaper to replace then to repair... if not impossible to repair.

Inspect the frame.. to check for any debris or loose fasteners.. but I am afraid that these will need to be replaced.

Best of luck

I have a set of Steiner Military Marine 7X50 binoculars and now they don't seem to be focusing "together" If you look through one eye cup it looks fine, same as the opposite side. But when you...


I think you mean the two sides are not quite pointing in the same direction. This is called collimation, as in "the collimation is out". Alignment would be the everyday word. In binoculars, collimation faults are usually the result of a knock causing one of the prisms to shift slightly. It can be simple to put right, for a skilled person who knows what he is doing, if adjustments are available. Or the binoculars may need disassembly and an optical bench. I imagine that you would be able to replace these more cheaply than fix them, unless they are very high quality or collectable. I have made a mess of a few pair, and had a few successes, always with binocs that were uneconomic to have repaired professionally.

Double image occured after the omega 40 X 70 binoculars were dropped


There are a series of lenses and prisms inside the binoculars. When the unit was dropped one of more of those elements have been dislodged and that is what is causing the double image. You can check with the retailer to see if there is a repair center in your area. The way these units are put together they are difficult to take apart, repair, and put back together. Depending on the cost of the unit you might be better off replacing them. Check with the retailer to see what they say.

I am seeing a double image whel I look through my binocular.


Hi,

Most binoculars should allow you to grip the two sides and pull them closer together to fit the distance between your eyes.. Have you tried this?
What you should see is the two images come together to form one.

If you have tried this already and you still get the two images then it's possible the model is just too wide for your eyes.. If they're new you could try return them for another type that fit better..

If this works for you then here are the instructions for setting up the binoculars to give you the best result for your eyesight..


This is more common than you would think.. Here's how to set up a pair of binoculars to suit yourself.
Any good binocular will be able to do this and the reason is to allow you to adjust them for the difference in strenght between your two eyes. I wear glasses myself and sometimes contact lenses so it's good to be able to quickly adjust them.

1. turn the binoculars over so you are looking at the underside.
2. on the eyepieces can you see on one eye(usually the right eye) a little plus - minus marking. The eyepiece should be able to rotate a little to each side of this marking.
3. Set the rotating eyepiece to the middle setting.
4. Look through the binoculars as normal and bring the two sides together until you form the two circles that you see into one.
5. Pick an object app 10 meters away.
6 Presuming that the adjustable eyepiece is on the right hand side then close your right eye, look at the middle distance object you chose with your left eye and use the central focusing knob/wheel in the middle to bring your left eyepiece into focus.
7. Now, close your left eye and adjust the rotating right hand eyepiece while looking at the same object until your right eyepiece is in focus.
8. The binoculars should now be set for the differences in strenght of your eyes and you can use the middle focus control as normal.

Most binoculars have a soft rubber eyepiece that can be folded back for people who wear glasses but I, like most people I know who wear glasses, find it horribly uncomfortable.

This method allows you to set them for yourself and if someone else uses your binoculars you can quickly reset them for you.

Hope this helps...


- Oh yeah, sorry, forgot to mention.. This set up is so you can use them without wearing your glasses.. Much more comfortable!!

I have a jason 2000 and when i look through it i see double and was wondering how to adjust it back to be able to see right


Hi,

You should be able to grab both sides of the binoculars and pull them together until the two images merge into one.. If you've done this already then the chances are that this model is too wide for the distance between your eyes (It happens more than you would think!!)
If this is the case, and they're new, you could try returning them to exchange for a better fitting pair..

Here are the instructions for setting up binoculars to suit your own eye-set and strength. You should be familiar with this when buying binoculars so you can test them in the shop..
The model you have is permafocus so you won't be able to adjust the focus but the first part should get you started..

The 2 eys don't focus together nikon I can't fine focus the right side focuser as i shold It turned all the way.


Try these instructions

http://www.bestbinocularsreviews.com/how_to_focus_binoculars.php

if that doesn't work your binoculars might be out of alignment. That requires taking the binoculars apart which is best left to a technician. Your binoculars might be under warranty. I would contact Nikon before I would ever attempt to take my binoculars apart.

I hope that they just need to be focused properly and that this was helpful.

How to put lens back together on a Bushnell Permafocus 17-5012. Lens had fallen in and now I have it appart but do not know what goes first,and so on.


Hi,

I presume you have this fixed by now but if not I'd recommend getting it back to Bushnell for repair(is it still in warranty?)
The Permafocus binoculars need specific callibration and the risk of dust or moisture getting in while open is not worth the hassle..
