This is why I keep my cc sorted by creator. Makes it easier to find out where it came from and to keep alert for updates. You may be able to use S4pe to open this package folder and see who created it. Can get the tool

I usually click on the 'tag' column to put it in name (tag) order. Then either select the OBJD or the STBL line that will usually show the creator's name. You can then figure out where it came from. Once you have the package name you can delete it from your mods folder which is where eye mods go.
Hope this helps, otherwise I don't know any way to find unwanted cc than to remove all mods and start adding them back one by one. If you do this, or even if you just add a new mod, you should always open your pc/documents/electronic arts/sims4 folder and delete the localthumbcache.package file and, if there are any lastexception.txt exception notes (associated with the MCCC mod I think?), delete them too.
I never heard of the Sim Tray Importer, so thanks for that tip. I'll be checking that out!
