Passive vision vs. active attention

VerbGeneral ideaWhen to use
SEE Passive — things simply enter your vision. No effort or intention needed. You just see what's there.
WATCH Active — sustained attention over time. Something that moves or changes: TV, a game, a film, someone doing something.
LOOK (AT) Active — you deliberately direct your eyes. A specific point. Always needs "at" before the object.
A common exception: "See a movie" (at the cinema) is a fixed expression, even though you're actively watching it. Don't overthink it — it's simply the expression natives use.
