How do I remove the big lenses on the bottom of a pair of binoculars?

They are glued in with epoxy, to keep dirt, dust and moisture out of the binoculars. You’ll probably break the lenses before getting them out of the binoculars.

Go to Fisher Scientific for science project lenses.

Thanks. I’d easily just go out and buy some but I figured it would be more useful to re-use an old pair of binoculars.

Maybe those things you hacked up unscrew…

“Rubbery stuff”?
What’s the age of the binoculars?
The binoculars are made of…?

Were it me, I would put them bottom down in as small of a glass dish as I could find and soak the lenses in paint/lacquer thinner.

@ibstubro I decided to just order the lenses, didn’t know getting the old lenses out of binoculars would be so tricky lol.

Normally, the lenses just screw off.

I was curious about the ‘rubbery’ stuff because I bought a ‘yard totem’ (bunch of crap glued together that is supposed to be pretty) that has parts worth more than the whole. But I can’t get it apart. lol
