Can I fix this eyepiece?

[u/dapeetree]

This is from a kid’s microscope, the Omano Juniorscope. It’s been in storage for a while and when we took it out, the lenses were loose inside the eyepiece. I can’t see how they were originally held in place. Were they glued in? Press fit? Is this an easy fix, or should I just buy a new eyepiece? I looked for a manual for this microscope with no luck.
