Cleaning the ocular lenses of those center focus binoculars that move the oculars in order to focus is a little different than cleaning the oculars of independent focus binoculars and center focus binoculars that move the objective lenses to focus. Also, the oculars are not sealed at all , so they tend to get quite dirty.

Remove the screw holding the center hinge pivot cover in place, and remove the cover.
On most of these binoculars there is a screw on the retainer plate that that is locked in place by a small set screw. Remove the set screw. The screw is quite small, so take care not to drop or lose it
The plate is usually screwed tight. The proper removal method would involve a special wrench with pins that align with holes in the plate. A serviceable expedient is to catch the edge of the hole with a screwdriver blade and then tap the screwdriver to ”walk” or rotate the plate. It is best to use a cheap screwdriver. After it is loose, remove the plate with your fingers.
Lift the arm and associated ocular off, making sure neither end binds up. It may be necessary to gently pry the center pivot end off. If you lift one side and the other binds, then it is not too hard to break the arms. Keep track of which arm goes over and which goes under.
Clean the ocular lens with a cotton swab tip wetted with optical cleaner, followed by a dry cotton swab. Check for cleanliness.
Replace the oculars and arms going to the center pivot. Then screw in the plate. Note that on one arm assembly (usually the left one) there may be a hole the arm that needs to be lined up with a pin.
Replace the washer and screw on the plate. Note that the set screw hole in the plate ( A ) will have to line up with a relief hole under it. ( B ) Walk the plate into alignment by tapping the screw driver while watching for the set screw holes to align. Then affix the set screw.
Re-attach the center pivot beauty cover, with it’s screw.

I often get asked “Where can I get replacements for the [frequently missing] plastic eyecups for my Nikon JB-7 marked (older issue) 7x15 binoculars?” The answer is nowhere as far as I know, and I know of no eyecups of other binoculars that fit that particular model. Eyecups are often missing from miniature binoculars. Sometimes eyeglass wearers discarded them to correct eye relief, and sometimes they broke or stripped out or were removed and lost. Replacement parts were not available when the binoculars were new, and are less available now. Purchasing another [preferably cheap and common] binocular with parts that will fit and can be scavenged is the normal recourse to sourcing missing parts. But in general, parts from one manufacturer (not brand) may not fit another manufacturer’s miniature binoculars, due to minor differences. For my own convenience in sourcing missing eyecups, I created an eyecup interchange list, by physically trying a pair of eyecups on other binoculars in my collection. Keep in mind that a single brand and power of binocular may have been made by multiple manufacturers (I have documented at least 4 variants for Selsi 7x18 CF binoculars for example). So pay a lot of attention to JB manufacturer code numbers of what you are buying to get parts from. Because of all the variables, it is best to view my interchange list as being a “probability” chart, and while it certainly increases the chances of getting something that will fit, it hardly guarantees it. It is specific to brand, power, focus type, and manufacturer “JB” mark. I will expand this when I have nothing else to do (infrequent occurrence) and am overloaded with surplus patience.
