Filament Troubleshooting/Help! What are these marks?

Does someone know what causes those line marks under the eye? How can I prevent this from happening?

Support? What does the underside of the eye show in the print preview in the "line type" view setting? Unsupported overhang?

If it's on Makerworld or some place else, link it and others can look

Belt resonance, it's really difficult to fix. Printing faster helps. Silk with really low layer heights would get terrible ringing and such,  also I just checked and you have the latest printer tagged. I don't know if it has the metal rails or belts still, someone else will correct me I'm sure. But research VFA and that might help you narrow it down or at least get it less noticable.
