Why do I see 2 images through binoculars?
Double vision usually indicates that the binoculars are out of collimation. Now, what is collimation? It is the process of aligning all components in both lenses of binoculars to bring light to its best focus. If this process somehow gets interrupted, the binoculars register different images on each side.
How do you fix binocular vision dysfunction?
How Do You Fix Binocular Vision Dysfunction? BVD is treated by correcting the eye misalignment. This is done with our specialized micro-prism lenses, which bend light in such a way that the image seen by the eye is moved into the position it needs to be in order to once again realign the images.
Can you realign binoculars?
The process of collimating and aligning a pair of binoculars requires a special optical jig and extensive training. The only thing the average person can do at home is adjust the collimation in one or both sides so that the images can be merged. This is done by slightly uncollimating one or both of the optical paths.
Is binocular double vision serious?
Binocular double vision is only present with both eyes open. This distinction is very important because monocular double vision is never dangerous, while binocular double vision can be caused by some serious neurologic conditions.
How do you fix collimation in binoculars?
The collimation screw tilts the prism against the tension of the spring clip. Look through both eyepieces, and rotate each screw by no more than one eighth of a turn at a time to see what effect it has on the image, then return the screw to its original position.
Can binocular double vision go away on its own?
Double vision may go away on its own, but people should still see a doctor. The most important part of the examination is the eye examination, but usually imaging is needed.
What causes sudden double vision?

What is double vision in binoculars?
Double vision in binoculars occurs when they are out of collimation (a term used to indicate direct entrance and exit of light through both lenses). There is a situation when the path which light follows may get distorted resulting in a different image from two sides.
Why can’t I focus on anything when using binoculars?
Not being able to focus on the minute details of your favourite object can be very frustrating. Double vision problem in binoculars happens due to numerous reasons i.e. mishandling, carelessness etc. but don’t worry much.
Why do my binoculars have two copies of the same image?
If you look through your binoculars and see 2 copies of the same image, then this is probably a problem with your collimation. Collimation is the position of the prisms within the binoculars, and if they’re not centered correctly, then they need adjustment for a proper image.
Is it possible to fix double vision?
However, if you want to do it yourself, then it’s possible with some patience. Be prepared for some trial and error as you adjust the alignment screws and try to center the image. When you’re done, the double vision should be all gone.
