Add-on eye cups are available from any telescope/binocular dealer. You should be able to get pair from them. Some camera stores carry them as well.

Put the eyepiece with the largest number written on it into the telescope. DO NOT use the 2x barlow if you have one. Go outside during the day time and practice focusing on a distant object.

The moon should be your first target.

Hi,

You should be able to grab both sides of the binoculars and pull them together until the two images merge into one.. If you've done this already then the chances are that this model is too wide for the distance between your eyes (It happens more than you would think!!)
If this is the case, and they're new, you could try returning them to exchange for a better fitting pair..

Here are the instructions for setting up binoculars to suit your own eye-set and strength. You should be familiar with this when buying binoculars so you can test them in the shop..
The model you have is permafocus so you won't be able to adjust the focus but the first part should get you started..

This is more common than you would think.. Here's how to set up a pair of binoculars to suit yourself.
Any good binocular will be able to do this and the reason is to allow you to adjust them for the difference in strenght between your two eyes. I wear glasses myself and sometimes contact lenses so it's good to be able to quickly adjust them.

1. turn the binoculars over so you are looking at the underside.
2. on the eyepieces can you see on one eye(usually the right eye) a little plus - minus marking. The eyepiece should be able to rotate a little to each side of this marking.
3. Set the rotating eyepiece to the middle setting.
4. Look through the binoculars as normal and bring the two sides together until you form the two circles that you see into one.
5. Pick an object app 10 meters away.
6 Presuming that the adjustable eyepiece is on the right hand side then close your right eye, look at the middle distance object you chose with your left eye and use the central focusing knob/wheel in the middle to bring your left eyepiece into focus.
7. Now, close your left eye and adjust the rotating right hand eyepiece while looking at the same object until your right eyepiece is in focus.
8. The binoculars should now be set for the differences in strenght of your eyes and you can use the middle focus control as normal.

Most binoculars have a soft rubber eyepiece that can be folded back for people who wear glasses but I, like most people I know who wear glasses, find it horribly uncomfortable.

This method allows you to set them for yourself and if someone else uses your binoculars you can quickly reset them for you.

Hope this helps...


- Oh yeah, sorry, forgot to mention.. This set up is so you can use them without wearing your glasses.. Much more comfortable!!

Try www.telescopes.com They have a wide selection of standard eyepieces.

Difficult to answer specifically without knowing the model. But binoculars are designed to view objects in the distance. They all have a limit as to how close they will focus based on the magnification and design. Objective lenses that are far apart such as on a porro prism binocular will not focus very close. The nature of the design of having the objectives further apart than the eyepieces doesn't allow it. When trying to focus too close the image will appear blurred and double. That is the nature of the design. 9 feet or 3 metres is considered quite close to focus a binocular and is usually for a model designed to do this such as a roof prism where the objective lens and the eye lenses are inline. A specialty binocular such as the Pentax Papilo will close focus to 50 centimeters. It has been designed so that the objective (large lenses) lenses converge.

Take into account when focusing that binoculars are also designed to compensate for differences in each eye. One of the eyepieces either right or left will adjust seperately. For binoculars with a center focus ring. First focus using the center ring with one eye covered. The eye that should be covered is the one that doesn't have the adjusting eyepiece. When the image is clear close the eye you have just used and leave the center focus alone. Focusing on the same spot look through the eyepiece that adjusts and turn the eyepiece ring until the image is clear. Now all you have to do is focus using the center ring only as the binoculars are adjusted for each eye.

Some binoculars do not have a center focus and each eye will adjust seperately.

There is no reference to Jason scopes on their website, here's some of the history if your interested: Jake Levin founded Jason/Empire, Inc. in 1947. Jake and his son,
****, started the business by importing binoculars from France, as
well as cigarettes and pearls from the Orient. The product was sold
to jewelry stores and catalog showrooms. The company's name was
created by shortening the name of Jake and Son, to get Jason. Empire
was the name of a brand of products the company sold. Jason's
original location was on the 8th floor of a building at 12th and
Walnut in downtown Kansas City, Missouri. The company later moved to
a facility in Kansas City on Warwick Boulevard. As the business
continued to grow, **** was responsible for the expansion and
evolution of the binocular and telescope business into a major
competitor in the U.S. Sports optics market.
Carson Companies, Inc. of Minneapolis acquired Jason/Empire, Inc. in
1977. In 1987, Jason introduced the Perma Focus binocular. This
patented binocular eliminated the need for focusing and revolutionized
the binocular industry. GlassOn, the first binocular exclusively for
eyeglass wearers, was introduced in 1991. The eyeglass wearer could
obtain a wide angle, full field of view when using the binoculars
while wearing eyeglasses. Other innovations included: the graphite
binocular, upscale consumer packaging, **** packaging, the Easy
Track telescope mount, and the telescope dual-position diagonal
eyepiece.

In 1992, Bausch & Lomb a.k.a. Bushnell, purchased Jason from Carlson
Companies and moved the sports optics operation to the current
facility in Overland Park, Kansas. The name of the division was
changed from Bushnell to Bausch & Lomb Sports Optics Division.

Bausch & Lomb divested the Sports Optics Division in 1995 and Bushnell
became a wholly owned subsidiary of Worldwide Sports & Recreation, Inc
(WSR). WSR was a leading designer, manufacturer, and marketer of
brand name sporting goods and outdoor-recreational products.

Since then, Bushnell has changed hands again and the Jason name has
been discontinued. It is no longer used in new products produced by
Bushnell and many of the more popular models were simply rebranded as
Bushnell models.
