Morphology

antiblue + filter

The phrase is transparently compositional: 'anti-' (against/reducing) + 'blue' combined with 'filter' clearly yields a device that reduces blue light. This mapping is cross-linguistically common (e.g. 'blue light filter' / 'filtro de luz azul') so a B1 learner who knows the parts would readily infer the intended meaning.

Etymology

Antiblue filter comes from its simple parts: anti meaning 'against', blue the colour, and filter something that blocks light. So it names a setting or device that blocks blue light from your screen to 'reduce eye strain' and 'help sleep'.
