Focusing the diopter adjustment ring will ensure your birding binoculars are properly tuned for your individual vision.

While a simple, inexpensive pair of binoculars may only have one focus adjustment to blur or sharpen both barrels at once, most binoculars have both a dual adjustment and a diopter adjustment ring that will focus a single barrel.

This is essential for the clearest images, because even a birder with excellent vision will have different visual acuity in the right and left eyes.

The diopter adjustment, then, allows for focusing with a single eye to calibrate the binoculars for that difference in acuity. After they are properly adjusted, the central focus wheel will adjust both barrels simultaneously to maintain that optimum adjustment for viewing at different distances.

For the best possible images with your binoculars that will give you the sharpest looks at birds and the tiny details necessary for proper identificationit is essential to focus the optics' diopter.

While different binocular models may have slightly different focusing methods, the basic technique is the same for all binns. If you have carefully aligned your diopter for the best image but still have trouble with blurry images, there may be other ways to improve the focus of your binoculars. Birding binoculars are expensive, and knowing how to use them properly begins with adjusting the focus to suit your eyes.

If you have the diopter adjusted correctly and there is no other explanation for a blurry image, contact the optics' manufacturer about the possibility of a repair or replacement. Find the diopter adjustment. For most binoculars, the adjuster knob is integrated into the eyepiece of one barrel, most commonly for the right eye. If the diopter adjustment knob is on the center focus wheel, it may snap in or out to make the adjustment. For a central diopter, check the binoculars' instructions to learn which barrel is affected as this adjustment is made.

Set the diopter adjustment to zero before beginning to focus. This will ensure the best possible focus result that is tuned for your eyes and your vision needs. Close the eye or cover the barrel that includes the diopter adjustment knob.

Look only through the other barrel with the appropriate eye, as this adjustment will not work if you use the right eye to look through the left barrel or vice versa.

Covering the barrel may be easier if you have trouble closing just one eye, as it is important to avoid squinting that would change the shape of your eyeball and affect the necessary focus. Use the center focus wheel to get a clean, crisp image, focusing on an object feet away. Choose an unmoving object in good light to ensure the best focus. Uncover the diopter adjustment barrel or open your eye and cover the opposite barrel or close the opposite eye.

Looking through the appropriate barrel with the appropriate eye, use the diopter adjustment knob only to change the image focus until it is as sharp and clear as possible for that eye. Uncover both barrels and use both eyes to check the overall focus. Use the center focus wheel only and check objects at different distances and in different types of light to verify the image clarity.

Choosing the right binocular for your specific application can be a challenge and this guide is intended to help you understand binoculars better. Consider when, where, and how often you plan to use the binocular in order to select the right combination of features that are right for your needs.

Compact and wide angle binoculars are great for outdoor activities and getting closer to the action watching sporting events at stadium. Compact binoculars are usually found at 7x to 10x magnification ranges. Compact binoculars are easy to store in your pocket or on a strap around your neck and the wide angle presents a good field of view. For long range shooting, such as varmint hunting, a 12x to 16x magnification is best. At larger magnification, you will need to use a tripod or to stabilize the binoculars, as the image will be very shaky if used in standing position.

The shaking of your hands is amplified by the larger magnification. The standard binocular for birding is an 8x42 binocular. To see more details on smaller birds at greater distances, you may opt for a 10x or a 12x magnification with a 42 or a 50 millimeter objective.

Longer eye relief and a close focus are also great features to have on your bird watching binoculars.

How to Choose the Right Binoculars

Since you're on the water, a high magnification binocular is not advised. Most commonly used magnification is a 7x, but 8x and 10x are also chosen by some mariners and boating enthusiasts. A 42 or a 50 millimeter objective lens should be used. A larger objective lens, waterproof and rubber armoring are main features to look for in a marine and boating binocular. Compact binoculars with a wide angle are great for concert and theater viewing using a binocular.

Tap Tap to Zoom. About the Author.The Jason binoculars company got its start in when Jake Levin and his son Dick began importing binoculars from France. Demonstrating a diversity of interests, their imports also included pearls and cigarettes from the Orient.

Their early optics customers included jewelry stores along with then popular catalog showrooms. Although they started out as "Jake and Son," the name was soon shortened and formalized to "Jason" with headquarters offices in Kansas City, Missouri. Empire, which evolved as part of the firm's name, was a brand of products sold by the firm in its early years. Dick was the one whose vision promoted their binoculars and telescopes into a competitive force in the United States market for sports optics.

Jason binoculars were one of the first to be marketed as "auto focus" binoculars. Their focus was permanently set at the factory for viewing activity at about 50 feet 15 meters distance or more. They enjoyed some popularity for stadium and racing events, particularly in chilly weather.

Jason's InstaFocus design was indeed popular with consumers briefly after its introduction and still has a number of strong supporters. Bushnell sold Jason's auto focus design among its own product line offerings for a period of time. Since then, the Bushnell company has been bought again and the Jason brand name is no longer used with new Bushnell products.

The term PermaFocus which was associated with the Jason binoculars sold by Bushnell, however, is still used with certain Bushnell models which are offered for sale today. At the time of this writing, the Bushnell PermaFocus models in the 10X42, 10X50, and 12X50 configurations which we considered had prisms made from BK-7 glass and the optics were " fully coated. Since there isn't a diopter-type focus adjustment for either of the eyepieces, you'll want to be familiar with how that may impact your viewing experience.

If you're looking for one of the popular roof prism designs, you'll want to check out the best binoculars page. We've heard from a number of readers who wrote to say that the previously enjoyable covering on the barrels of their Jason binocular had turned sticky. They asked "What can I do to remove the stickiness on my Jason binocular's barrels?!?

If this is your predicament, we've not found an easy solution. However, it is possible to get rid of that sticky layer on most Jason binoculars by using some isopropyl, or "rubbing," alcohol, a clean cloth, and some elbow grease. Initially try it on a small spot in an area of the binocular where it won't present a problem if it doesn't work as expected. It's worth noting that it can be a bit messy by the time you're done and some have found it helpful to wear rubber or latex gloves for the job.

We frequently receive inquiries about the possibilities of repairing a Jason Empire binocular with broken or missing parts. Often the inquiry is for an instrument which hasn't seen much use and is in new or nearly new condition other than the damaged or missing part. After a number of such inquiries, we started asking optical repair technicians whose skills and abilities we value and respect if there might be a particularly good approach to repairing these once popular binoculars after they've been damaged in one way or another.

The response was fairly uniform: while there are a fair number of Jason Empire units still around, the lack of replacement part availability and quality of the instruments' original construction make repairing them difficult.

Usually the cost of repairs is more than the binocular is worth, no matter its condition. Jason Advertisement from If you have a Jason binocular of sentimental significance to your family that has suffered damage or loss of a part, you may find it worth the price to have it repaired. If we were looking for an eyecup, lens cover, or other part or accessory, this is where we would look. Unfortunately, used Jason Empire binoculars are not as plentiful as they used to be and many are finding it difficult to impossible to find a match for their instrument.

If you're interested in information about when your instrument may have been manufactured, we have found it very difficult to locate data to narrow the manufacturing period more than what we've provided above, but have found that finding dated advertising for your particular model may be the easiest route to follow.

Such advertising can sometimes be found in older outdoor magazines - you might try searching Google's scanned books and magazines. If you can borrow a newer binocular from a friend or relative to try for a few days, you may be pleasantly surprised to see the results of improvements in binocular optics which have taken place over the last five or so years.For anyone interested in collecting old binoculars then follow me and lets see what we can discover.

Binoculars have been around and in general useand good quantity since the s. They are the bygone instruments which have been widely used for a long time now, and are still being produced today. Indeed today's instruments are as easily recognizable as those produced many years ago, especially in their design shape, although the technology regarding materials, prisms and lenses has taken great leaps forward.

Now, as we have moved into the 21st century, it is still relatively easy to find such fascinating old instruments dating from the middle-late s to the early-mid s. And there is a fascinating history attached, as these instruments were used for pleasure and work, through peace and war.

Don't forget, apart from the good times we have had two world wars and many minor wars since Queen Victoria reigned, and the military as well as the general public used these instruments in great numbers, and indeed still do. At the time of WW1 there was a shortage of binoculars, so the military 'bought in' a lot of binoculars.

These binoculars could have been French, German, or from private individuals ect, wherever they could find them. The Germans decided during the war that they did not want the allies to know where their optics were manufactured to stop the bombing of the factories?

This is just a list of some of the main codes as there were rather a lot, and they can be looked up on the internet. Many of these binoculars were used right through to WW If you look into the history of some of these makers, you will find that many of them started out in the Optical business such as Opticians and lense makers.

This means that the instrument was tested at - The Kew Observatory. The letter 'N' is followed by 'P' over 'L' and a number, for instance - '43', which would mean it was tested in The sign was also used as a mark of testing, so a full Broad Arrow meant the instrument was up to standard.

Anyway, during WW11 France was 'occupied' and so Binoculars made in France for Germany were given a code which was stamped on the binocular. Also during WW1 when there was a huge shortage of binoculars, the British 'bought in' Binoculars from all sorts of places including France.

Bought in binoculars were stamped by the British Military, so you may have a pair of French Binoculars marked like this - for example. A lot of Opera Glasses were produced in the s and early s, but I don't think anyone made such beautiful glasses as the French. Depending on the level of decoration and condition, some of these Opera Glasses can be quite ex[pensive.
