How to: Adjust your Binoculars & Get The Best Viewing Experience

Why do you need to adjust your binoculars? Because if you properly calibrate and focus them, you’ll allow your eyes to be comfortable and relaxed. Plus, it will only take less than or about a minute to do it! So let’s start calibrating to improve your viewing experience.

  1. The Center Focus Method

Inexpensive binoculars usually come with a focusing dial at its center. Follow the steps below to adjust them:

  1. Identify which eye has a stronger vision.

  2. Choose a faraway object.

  3. Focus the eyepiece to your dominant eye. If your right eye is dominant, you should close your left eye or cover the left lens and adjust the dial until the object is focused.

If in case you can’t get the object focused, then there must be a few differences between your eyes’ vision. The best thing to do is purchase a new pair of binoculars with higher quality. This will allow you to experience less eye strain for longer scanning sessions.

  1. The Individual Eyepiece Focus Method

If your binoculars come with a more expensive price tag, it may also consist of individual eye adjustments. These are the things you should do:

  1. Look for a distant object and make sure it’s in the common range of the area you’ll be scanning.

  1. Aim your binoculars at that object.

  2. Close your left eye or cover the left lens tube and carefully adjust the focus on your right eyepiece. Continue adjusting until the object is perfectly in focus. Now do the same with the other eyepiece. Close your right eye or cover the right lens tube and adjust the focus on your left eyepiece.

That’s it! Easy as pie, right?

  1. The Diopter Method

Nowadays, binoculars come with a diopter adjustment. This controls one of the eyepieces, usually the right eyepiece. Setting the diopter correctly will make up for the dissimilarities in vision between your eyes—a problem we had in the first method. Here are the steps:

  1. Look for a distant object.

  2. Ensure that the diopter is set to zero.

  3. Identify the side of the binocular that has the diopter then cover its lens.

  4. Keep your eyes open and relaxed. Don’t even think about squinting! If you want to have the best viewing experience, make sure your eyes are open.

  5. Aim your binoculars at the distant object you chose in Step 1.

  6. Adjust the focus dial until you get a sharp image of the object.

  7. Next, cover the left lens with the lens cap.

  8. Without laying even a finger on the focus dial, adjust your diopter wheel until the object is focused clearly.

  9. Lock the diopter down. This is only applicable if your diopter comes with a lock feature.

If you’re constantly altering your target range, you have to refocus every time to acquire the best view of the object.

Now, you’re done preparing your binoculars for the best viewing experience! Congratulations!
