Collimation is a term used to indicate the direct entrance of light in both lenses of binoculars. When the light path in the binoculars gets blocked or distorted, it causes the binoculars to register different images on both sides.

Therefore, when you take your optics to action, the performance becomes significantly underrated. If you are out on a hunting adventure, then it limits your ability to spot your target accurately. In return, double imaging limits you from experiencing excellence in any outdoor adventure.

When you have double vision, at times, it becomes impossible for you to also distinguish between objects. The fixed double vision makes it impossible for you to tell what you are watching, especially if the object is moving.

What Causes Double Imaging On Binoculars?


Mishandling your binoculars could be the greatest reason why you have double vision. This can be done in numerous shapes, including how you carry and store the binoculars to how you use them, and the terrains of your usage. For instance, if you are hiking and your optics keep slipping off your hands and falling, there are higher chances that it will get loose.

In return, the alignment of passing light will automatically be distorted hence developing double vision. Also, if your device keeps falling every other minute, apart from losing alignment and becoming loose, it also experiences wear and tire.

This eventually leads to its breakdown and even if it has a convenient warranty, it will be ineffective sooner than you would expect. Additionally, when your binoculars develop an issue, the way you repair it matters a lot. Putting your creative skills into repairing your binoculars isn’t bad.

However, when you are not sure of what you are doing, it could lead to double vision. Even as you engage your creative minds, you also need to ensure that when you are unsure, you get help from professionals. This way, it will be easy to maintain quality viewing without possible eye strain. It is also good to learn how to get moisture out of binoculars.

Poor Adjustments

For you to get the best from your binoculars, you have to ensure that it is adjusted appropriately. Both lenses require to be adjusted to zoom on the same item at the same time for better focus.

The essence of the binoculars is to focus on a single image with both lenses. However, when one side adjusts more than the other, the image quality becomes distorted hence affecting the way you see through the lenses.

Additionally, when you adjust the binoculars prisms, it ensures that you will enjoy your adventure with accurate target observation. However, when you adjust the prism poorly, the results will not be as friendly. Poor alignment indicates that both lenses will not have the same image magnification.

In return, this will give you double imaging or worse inaccuracy. Therefore, when you use the binoculars to view, you will not be certain that the image you see is located at the exact distance you see it. Therefore it will impair your ability to make an accurate judgment on the things you see. This will therefore result in missed calculations when releasing the trigger.

When your one eye sees one inch differently from the other, it will automatically change where the bullet lands on your target. For instance, if one eye gives you an accurate bullseye and the other eye gives you different coordinates, your bullet will automatically land somewhere different. Another effect of the poor adjustment is that it hinders your ability to enjoy the adventure as you should.

For instance, if you are using binoculars for bird watching, double imaging will get you confused about the number of birds you are watching at a time. Also, it will be difficult for you to keep up with your target’s movements.

Avoid Feeding Your Curiosity

Curiosity is what killed the rat. The need to know beyond what you see always has consequences whether positive or negative. It is easy to be tempted to know how the binoculars look in the inside. However, as much as this feeling will come, keep reminding yourself you are not a pro mechanic.

The much you are allowed to go is only perform deep cleaning, adjust the strap, and rotate the focus knob.

Therefore, it is essential to avoid getting yourself in a place where you will be responsible for breaking the device while feeding curiosity.

Now using your binoculars, check through the lenses to see which of the two is worse off to start with it in fixing.

At times, you may get double vision simply because one of the lenses is not aligned, while other times it could be a problem on both.

However, even if both lenses have an issue, start with the one that is completely off, work on it then move to the other. Aligning one lens after the other also allows you to fix the issue gradually until you get to the point where it’s all better.
