Not everyone knows how to set a binocular's diopter. We're here to make sure that you're using your optics correctly to get the best possible view of every bird!

Are you aware that most binoculars allow you to adjust their barrels separately to account for differences in vision between your two eyes? By setting your binocular's diopter, you're ensuring that both eyes can effectively focus on a subject to get the best views possible.

Instructions for Setting Your Binocular's Diopter

No time to watch a video? No problem! Here are our step-by-step instructions for setting the diopter on any binocular.

Step One: Select a subject and look at it through your binocular. Keep both eyes open.

Step Two: Cover the right barrel so that you'll only be able to see with your left eye.

Step Three: Turn the focus wheel to get a sharp image of the subject.

Step Four: Cover the left barrel. You're adjusting for your right eye this time, but keep both eyes open!

Step Five: Turn the diopter to bring the same subject into focus.  

Your binocular is ready to use normally! From now on, you only need to turn your focus wheel to zero in on a bird, butterfly, or any other subject.

Now that you're diopter savvy, you're ready to take on the world of bird watching with any birding binocular!
