Something that causes aberration or deviation, particularly in optics, a lens or optical element that introduces optical aberrations.
From Latin 'aberrare' (to wander from) plus '-tor' suffix meaning 'one who does or causes.' The term describes agents of optical distortion.
In optics, engineers spend millions perfecting lenses precisely to eliminate 'aberrations' caused by 'aberrators'—it's a field where the thing you're fighting against literally has a technical name.
