Hello. Let me take you directly to the source

call customer service at 800-423-3537 pressing option 1. you will need to send this into repair to procure the parts you need.

You'll need to measure your eyepiece in "mm". Also determine if your eyepiece has an outer ring the eyepiece will slip over. You can find eyecups/guards on Ebay. Search under Binocular Eyecup or Binocular Eye Guard. There are also eyecups under "rubber eyecups/rubber eyeguards" but alot of these are for Microscopes and may not fit. You will need to pay close attention to the mounting type and measurements.

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.

they were famous for that, because the screwpin that holds the eyepice shaft is metal and the groove that it rides in is plastic, and eventually gets jammed....look where you put your fingers to adjust eyepieces. should be small metal plate in center of hinge(sometimes with bushnell logo) that will simply pry off by using small screw driver,and now you will be able to see if the screw is loose or damaged. good [email protected]

first open and close the binoculars untill they fit you eye width,now adjust left eye with the flat section located on the center hinge,now turn right eyepiece till clear. note: once you have adjusted right eyepiece you only have to leave it in that position in order to focus from near and far.........good [email protected]

The distance between the centers of the eyepieces of your binocular must be the same as the distance between your pupils. This distance is adjusted as follows: 1. Focus on a distant object. 2. Pivot the two halves of your binocular farther or closer apart until you can see a single unobstructed, circular field of view. Make sure to focus on a distant object when you do this because when you focus on a close object you always see two slightly overlapping circular fields. Your binocular may have a scale on the top, between the eyepieces, to help you remember this setting.
