One image is slightly above the other at all distances. After using the binoculars for even a couple of moments, my eyes are strained. The problem was present when the binoculars were purchased, however...


The oculars are not aligned properly causing double vision. Check on the binoculars to see if there is a place to adjust the alignment of either of the oculars. Look for any loose screws that may cause the two oculars to be out of alignment.
If this is not the case try adding some torque to the binoculars to see if the will adjust to where they will both point in the same direction. The eyes can fuse disparate images slightly but there is a very small range that they can handle. If the two images are separated by more than this small amount it will cause eye strain and double vision.

Focusing problems


Hello Samaro,

This effect is produced when the tho sides of the binoculars are not focusing the same.
Since you sayit is present at long distance, it might be that one barrel is stuck and is not focusing the same as the otherone when you scroll the middle "focuser".

What you can do is open it up and try to clean it, also see if there is something, that is making one of the lenses not move forward as far as the other one.

Good luck,

Accidentally dropped Bushnell Legacy WP 10 X 50 binoculars. Now they have a double image. Is this something that will need professional repair?


Yes, and unfortunately it will cost more than these binoculars are worth. What has happened is that one or more of the prisms inside the binoculars has shifted, putting them out of "collimation", or alignment.

You could have a go at this yourself, as a proper repair is not economic, but treat it as a learning experience.

I have a pair of Plastimo military binoculars which have been fine up to now, but suddenly, despite being able to focus using the two eye piece controls, I cannot get anything other than a double image, no...


Hello - I never had Plastimo before but I have had a similar problem with double vision on a very similar looking pair of binoculars.
The eye piece movement just re-aligns eye focus differences , a double image usually means one of the lenses has moved inside the main tube. (usually from a knock/fall etc)
Can you rotate either one of the tubes ? On my pair I had to rotate anti-clockwide and found a prism inside that had slipped after a fall -
Close one eye and try to gauge which side is the best side -- Ray

I dropped my Nikon Action Lookout III binoculars, ...


The same happened to my Mizar 10X25 I tried things like moving the front lenses but then I discovered that most probably the binoculars fell on one of the four corners, this caused the tubes' direction to be twisted. It could be that the left is pointing slightly down or the right is pointing slightly up, which is essentially the same, and which is what happened to mine. You can discover this miss-alignment by watching using both eyes and then close and open one of them the phantom image will appear and disappear. What you have to do is apply a force with your hands twisting the binoculars one tube up and the other down and hold where you can see clear, I just discovered this and it works, I think I should be able to re-align them again, but I haven't faund how to do so. If you find a different solution please let me know here: gregsoli@yahoo.com

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 bought these for my husband. In trying them


Difficult to answer specifically without knowing the model. But binoculars are designed to view objects in the distance. They all have a limit as to how close they will focus based on the magnification and design. Objective lenses that are far apart such as on a porro prism binocular will not focus very close. The nature of the design of having the objectives further apart than the eyepieces doesn't allow it. When trying to focus too close the image will appear blurred and double. That is the nature of the design. 9 feet or 3 metres is considered quite close to focus a binocular and is usually for a model designed to do this such as a roof prism where the objective lens and the eye lenses are inline. A specialty binocular such as the Pentax Papilo will close focus to 50 centimeters. It has been designed so that the objective (large lenses) lenses converge.

Take into account when focusing that binoculars are also designed to compensate for differences in each eye. One of the eyepieces either right or left will adjust seperately. For binoculars with a center focus ring. First focus using the center ring with one eye covered. The eye that should be covered is the one that doesn't have the adjusting eyepiece. When the image is clear close the eye you have just used and leave the center focus alone. Focusing on the same spot look through the eyepiece that adjusts and turn the eyepiece ring until the image is clear. Now all you have to do is focus using the center ring only as the binoculars are adjusted for each eye.

Some binoculars do not have a center focus and each eye will adjust seperately.

Image appears double and slighly off when viewing


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!
