Eyes are very important to us and we all take care of our eyes.  Once our eyes are damaged, it can affect our daily life.  So for photographers who like to use binoculars, there’s a big worry: can binoculars hurt your eyes?  So let’s take a look at that.  

1. Do binoculars affect vision?  

Even if you’re not a professional binocular photographer, you probably have to use binoculars at some point in your life.  Most of us don’t look at birds or stars or conduct some kind of investigation with the help of these gadgets.  But you may just decide to get a better view of the sights on this rare sightseeing trip.  In this case, it is important to understand how binocular use will affect your eyes.  A lot of times, it’s not the binoculars that are harmful.  Rather, it’s how you use them and what you try to see by using them.  

2. How to avoid hurting your eyes?  

There are many ways to avoid damaging your eyes, and I’ll cover them in this article.  It involves two things: the first is choosing the right telescope.  The second is knowing how to use binoculars.  

Otherwise, your optical equipment may harm your eyes.  If you have binoculars or plan to buy one, you must know not to look at the sun through binoculars as it can damage your eyes.  To do this, you can purchase special filters for your objective lens, called solar filters.  

Use your binoculars carefully and try to avoid dropping or tapping on them.  If you don’t understand or follow simple rules, the effects of binoculars on human vision can be serious.  If you have astigmatism, you will need to purchase binoculars with at least 15 mm eye distance.  

Be sure to twist up the blinders on your binoculars so you can see images without black spots and avoid eye strain.  Be sure to adjust your vision by turning the center focus wheel until you see a clear image.  It is used to adjust the image of the left eye.  Be sure to adjust the vision in your right eye by turning the diopter on the right tube until you see a clear image.  

3. How to use binoculars correctly?  

(1) Use the lowest magnification possible  

The lowest possible magnification of binoculars not only magnifies images but also reduces handshaking.  The higher the magnification of your eyes, the more your hands shake.  

(2) Use binoculars with the correct objective

Binocular lenses should be kept away from the eyes.  The larger the image, the more light it concentrates.  For example, when using binoculars in low-light situations, the lens should be as large as possible.  

(3) Adjust the center hinge of the binocular 

The two binoculars are connected by a central hinge.  It is necessary to adjust the binocular to get a clear image.  

(4) Adjust the eye mask  

The eye mask helps to position your eyes at the correct distance from the eyepiece so that you can see the image without any dark shadows around the edges.  Users can increase or decrease the depth of the cup until the edges become crisp.  

(5) Set the diopter 

No two eyes work the same way, and this difference needs to be taken into account when using binoculars.  In binoculars, an eyepiece with diopter adjustment can help make up for this difference.  

(6) Train your naked eye  

Binoculars help magnify what the naked eye can see.  Training the naked eye to see small distant targets can be difficult.  This can be frustrating for you, but try to get as much of a wider view of an area as you can with the naked eye, and once you adjust your vision, see the rest of the field through binoculars to get a more limited view for accuracy.  

(7) Do not clean the telescope with your shirt  

One should never use a shirt, unlike the cloth used to clean binoculars, which can damage the fine glass of binoculars and leave scratches.  The scratches have severely blurred your vision in both eyes.  Only use a soft brush or compressed air or lens paper to clean the binoculars.
