How to fix double vision in binoculars Easy Steps and Tips

In this blog post, I’ll share some tips for fixing double vision in your binoculars.

Factors Affecting Binocular Vision It’s Working

What are Binoculars used for? Binocular vision is the ability to see with both eyes simultaneously, allowing us to perceive depth and distance accurately. When using binoculars, the two lenses work together to create a single, magnified image. This can be affected by factors such as the alignment of the lenses or the user’s eyes and can result in double vision or a blurry image.

  • It’s important to understand the basic principles of binocular vision to know how to troubleshoot issues with your binoculars. The two lenses must be properly aligned to ensure that the image from each eye is merged into a single, clear image.
  • Another factor to consider is the distance between the two lenses, which is known as interpupillary distance. This distance varies from person to person, and binoculars typically have a mechanism to adjust the distance between the lenses to match the user’s eyes.

Also, you should know how binoculars are rated.

Causes of Double Vision

Binocular double vision can be a frustrating experience, especially when you’re out birding, stargazing, or watching a sporting event. Understanding the common causes of double vision can help you identify the issue and correct it accordingly.


One of the most common binocular double vision causes is misalignment. This could be due to the binoculars being dropped or bumped, which can cause the prisms inside to become misaligned. Another cause could be the diopter setting, which is used to adjust for differences in each eye’s focus. If the diopter setting is not adjusted correctly, it can cause double vision.

Interpupillary Distance

Another cause of binocular double vision could be the interpupillary distance, which is the distance between your eyes. If your binoculars are not adjusted correctly for your interpupillary distance, it can cause double vision. This is easily corrected by adjusting the binoculars to match the distance between your eyes.

Quality of the Binoculars

Lastly, double vision can also be caused by the quality of the binoculars. Poor-quality binoculars may not have the same level of precision and alignment as high-quality binoculars, which can cause double vision. If you’re experiencing double vision in your binoculars, it may be time to invest in a higher-quality pair.

By understanding the common causes of double vision in binoculars, you can identify and correct the issue, allowing you to fully enjoy your outdoor activities without any visual interruptions.

Steps to Fix Double Vision in Binoculars

Double vision in binoculars can be frustrating and make viewing objects difficult. Here are some steps you can take to fix double vision in binoculars:

Adjust the Focus

Most binoculars have a focus wheel or knob that you can use to adjust the focus. Try turning the focus wheel until the object you are looking at appears clear and in focus in both lenses.

Adjust the Interpupillary Distance

Binoculars have adjustable eyepieces that can be moved closer or further apart to match the distance between your eyes. Adjust the distance between the eyepieces until you see a single, clear image through both lenses.

Adjust the Focus

Check the Diopter Adjustment

Some binoculars have a diopter adjustment, which allows you to fine-tune the focus for each eye. Look through one lens at a time and adjust the diopter until the image is clear and in focus.

Check the Diopter Adjustment

Clean the Lenses

Dirt, dust, and fingerprints can cause double vision in binoculars. Use a soft cloth or lens cleaning solution to clean the lenses, being careful not to scratch them.

Check for Damage

If none of the above steps help, there may be damage to the binoculars. Check for any visible damage to the lenses, focus wheel, or other parts. If the binoculars are damaged, they may need to be repaired or replaced.

Tips for Adjusting the Focus

Adjusting the focus is one of the easiest and most common ways to binocular double vision fix.

  • Start by closing one eye and adjusting the focus on the other eye until you see a clear image.
  • Then, switch eyes and repeat the process. If the image is still blurry or doubled, you may need to adjust the diopter, which is a small dial or lever near the eyepiece that fine-tunes the focus for each eye individually.
  • It’s important to note that focusing on one object may not always solve the issue of double vision. Sometimes, the binoculars may be misaligned or the lenses may be damaged or dirty. In these cases, adjusting the focus won’t help and other methods of correction may be needed. Also, have a look at how to keep binoculars from fogging up.
  • If adjusting the focus and diopter doesn’t solve the problem, try using a tripod or stabilizing the binoculars against a solid surface to reduce shakiness and improve the clarity of the image.
  • Additionally, make sure the binoculars are properly adjusted to fit your eyes and that you’re not wearing glasses or contacts that may be interfering with the image.

With a little patience and experimentation, you can find the right adjustments to fix double vision and enjoy clear, crisp images through your binoculars.

Tips for Adjusting the Interpupillary Distance

One of the biggest culprits behind double vision in binoculars is an incorrect interpupillary distance. The interpupillary distance refers to the distance between your eyes, and adjusting this distance on your binoculars can make a large difference in the clarity of your view. Can binocular double vision be corrected?

  • First, you will need to adjust the distance between the two barrels of binoculars. This can be done by holding the binoculars up to your eyes and adjusting the barrels in or out until you see a single, clear image.
  • Once you’ve adjusted the barrels, you’ll need to adjust the focus on each eyepiece.
  • Close your right eye and focus the left eyepiece until the image is clear.
  • Then, close your left eye and focus on the right eyepiece until the image is clear.
  • Finally, adjust the focus on the center wheel to fine-tune the image.
  • It’s important to note that the interpupillary distance can vary from person to person, so if you share your binoculars with someone else, you’ll need to readjust the distance to fit their eyes.

By taking the time to adjust the interpupillary distance, you can greatly improve the clarity of your view and minimize double vision.

Tips for Cleaning the Lenses

One of the most common causes of double vision in binoculars is dirty or smudged lenses. If the lenses are dirty, they will not be able to focus properly, causing the image to appear doubled. Cleaning the lenses is a simple but effective way to fix this problem. How to focus binoculars properly?

  • First, use a soft-bristled brush to gently remove any dust or debris from the surface of the lenses.
  • Next, use a microfiber cloth to wipe the lenses clean. Be sure to use a gentle touch to avoid scratching the glass.
  • If there are smudges or fingerprints on the lenses, use a lens cleaning solution and a microfiber cloth to gently clean the lenses.
  • Avoid using harsh chemicals or abrasive materials, as these can damage the lenses.
  • It’s important to clean the lenses regularly, especially if you use your binoculars frequently or in dusty or dirty environments.

How to Hold Binoculars Steady to Avoid Double Vision

How to adjust binoculars with double vision? When you’re using binoculars, it’s important to hold them steady to avoid double vision. Double vision occurs when the images from the two separate lenses do not properly align with each other. This can be caused by a variety of factors, including holding the binoculars improperly or not holding them still enough.

  • To hold your binoculars steady, first, make sure they are adjusted to fit your eyes properly.
  • Adjust the distance between the two lenses so that they are the same distance apart as your eyes, and adjust the focus for each eye individually so that the image is clear.
  • Next, hold the binoculars with both hands and bring them up to your eyes. Keep your elbows close to your body to help stabilize the binoculars.
  • Make sure the center of the binoculars is lined up with the center of your face, and that your eyes are looking through the center of each lens.
  • If you’re still having trouble holding the binoculars steady, consider using a tripod or other stabilizing device to keep them still. This can be especially helpful if you’re using high-magnification binoculars, as even small movements can cause the image to become unstable.

By holding your binoculars steady, you can avoid double vision and get a clear, crisp image every time you use them. Also, you should know what are the strongest binoculars.
