Re: canon 12x36 is binoculars
Your alignment is out in the vertical. There are two prisms on each side and you want to adjust the lower ( on the right side ) prism so that you correct the image in the vertical dimension.
Caution : it doesn't follow that just because the image seems to be out on the right hand side that it is the right side that fas to be adjusted. So be prepared to adjust the other side. Also the best is to adjust little bit on each side until alignment comes right.

This is a common problem with binoculars. One of the prisms has shifted and the two sides are therefore no longer in optical alignment (collimation). Unfortunately, fixing this requires a degree of expertise, which may cost more than you will want to spend. I have often taken old binoculars apart or found external adjustments that allowed me to realign them, but I have ruined a few pair this way. Not a good idea if they are valuable.
If you can find the paperwork and they are still in warranty, you might try to get Canon to repair them, but I suspect that they will say they have suffered an accident, not a manufacturing fault.
Chuck them away and replace them. Seriously. Your binoculars have suffered the most common fault which occurs to all makes and models: a bent or broken eyepiece yoke assembly.
If broken it cannot be fixed without replacing the whole yoke assembly, and on budget models like anything that Tasco sell it's cheaper to buy new and the spare part is probably unavailable anyway. If the yoke has bent then it's virtually impossible to unbend it without breaking it, and even if you do it's usually not accurate enough. So you try again and it breaks... On the rare occasions where you're lucky enough to get it right, the yoke has fatigue cracks and soon breaks regardless. Due to the loads involved and the tiny contact patch, gluing is a waste of time and usually just turns a broken yoke into a weak and bent yoke.
Given that you can now buy very good quality similar or superior binoculars from Bresser and others for around £10 to £15 new any kind of repair simply makes no sense. There's nothing wrong with cheap binoculars in general, but you have a simple choice; pay a lot for top quality models which then have full after sales and spares back up or pay very little and replace them more often. Even then, the yoke assembly for a high quality brand will pay for around six to eight complete new pairs of low cost binoculars. Your call...
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!!
Your binoculars are known as the Zeiss Classic or what was once known as the Dialyt. They focus differently from the usual binoculars like those mentioned. The rear wheel is to focus both binocular barrels while using them. The front focus wheel is adjust the right eyepiece to suit your right eye. Binocular manufacturers take into account each eye is slightly different. To focus the Dialyt...First close your right eye and turn the rear wheel until the image is sharp in the left barrel. Leave the focus wheel alone. Now close left eye and adjust the front wheel until the image is sharp for your right eye. The image should now be clear and in focus for both eyes. It should not be needed to use the front wheel from now on. The rear wheel is what you will use to change the focus from near to far objects.
I was having a double vision problem with my Barska 10-30X50 zoom, 195FT/100YDS binoculars. One image was always higher than the other. This was tolerable at low zoom, but was further aggravated the more I zoomed in. I found that I could grasp both barrels and twist them in opposite directions (one side up, the other side down) and force the two images to merge--but that was a strain and an unpleasant viewing experience. As an experiment, while looking through the binoculars, I grasped the far end of the right barrel and twisted it on its axis. Nothing happened at first, but after a certain amount of resistance it began to rotate independently of the body. Lo and behold, this shifted the barrel's axis, and the image for that eye moved vertically! I turned it until the two images merged, and now I'm thrilled to say that the problem is solved! I don't have a clue if this would work on any other brand or model, but it's worth a try!
more than likely one or more optics have shifted, its hard to tell if it can even be fixed as some of the mass produced binoculars today are impossible to get apart without taking off the outside leather or rubber. you dont want to mess with it cause it will only get worse, and probably you will get dust etc. inside if you get it apart. if i can be of any further help contact [email protected]
What you see is fungus . It comes off very easily BUT if allowed to grow it will damage coating and glass because the organism releases hydrofluoric acid. So the key is to clean as soon as possible.
You can do this your self but be careful around the prisms because even slight movement here will upset your collimation ( will get 'double image')and then you will need to have your nbinocs aligned properly.
