"Optics"
Optics is the study of light or the instruments involved in manipulating it.
It does not work as a stand in for "perception".
Saying "they are worried about the optics" is like saying "they are just worried about the camera" when you mean "they are worried about how it looks".
It's (yet another) dumb FOX fluff word that people have taken to use because they think it sounds smart and fancy. It's not, it's fucking dumb.
Edit: btw, it follows the pattern of other words imposed on the American psyche by FOX in the same vein as "slant", "bias", "spin" and "partisan", all of which had their heyday until people caught on, and another one was needed for projecting the idea that truth is negotiable and that all sides and opinions are "equally valid" and a matter of opinion and motivated by personal agendas. I have been trying to make people aware of this for decades, it's an impossible battle, it's been an outspoken strategy of FOX and the Republicans for decades, and it makes me sick seeing how well it works and how easily it penetrates public discourse.
