Under the bottom of both eyes feel like someone punched me. Very sore... The whole cheek bone feels like a bruise. Nothing visible?

Pain. Sinus infection, allergy, tooth issues are probably first to rule out. If none of that is found, try warm compress to the area, Ibuprofen or acetaminophen. If other symptoms are present or if it is getting worse, see doc.
Get checked. You might have a problem with you sinuses, which is behind the bone that you describe. If it is persisting you should get evaluated.
