It's possible the first element in the eyepiece has come loose from its
frame. The evidence of glue around the edge could indicate that it was
already repaired at least once. Luckily the eyepiece on an OM-4 can be
completely disassembled for servicing. You can find the exploded parts
diagram on my web site here:
http://olympus.dementia.org/Hardware/PDFs/OM-4_exploded.pdf
The last page contains the diagram for the eyepiece. If you're technically
inclined and have a good assortment of tools, it's not too difficult to do
this repair. You will of course need to remove the top and then pull the
eyepiece out, so if you're not comfortable doing that, then leave it to a
qualified technician.
