His researches extended to almost every branch of physical science, but his most important work was of an optical character.
When you see something that makes your retina's erect

Usually, in a mainstream or social media context, jargon to describe the way in which an event or process will be perceived.

Shell Exec (2): "Blatant virtue signalling - you never fail Hank - I think that could be the most transparent bit of greenwashing in history! But those lycra boys will never buy it..."
British Cycling official: "wow, thanks, guys; we always knew the oil industry was really nice."
Often in a mainstream or social media setting, the way in which an event or process is perceived by others. Often related to the act of virtue signalling - optics are how a signal will be received/ "look".
Shell marketing exec (1): "we need to signal that our company is all about saving the planet, not making £8 Billion profit - and sponsoring those desperate muppets at British Cycling for a few million quid seems like a no brainer"
Shell marketing exec (2) "you've got it - the optics are great, although surely those fresh-air lycra boys won't buy it?!"
British Cycling: "thanks guys, you're so lovely, we cyclists always knew the oil industry was our friend"
