An optic is glass the focusses the beam, as opposed to being simply a lens/reflector combo. Most optics are cone-shaped and sit right on the emitter.

or plastic... KL1 has a plastic like one. I know because i accidently drilled into one!
So a reflector takes all the light and tries to emit all it can with minimal loss while also not defining the beam per se but having an impact on output? Reflectors have lens and sit at the emitter level?
An optic then just shapes the beam to attain an output (lets say tight spot)? They dont have lens and they usually sit above the emitter?
Do I have this right?

anything that bends light either to focus or to dissipate

Illum is right:
Everything we use to collimate the light, comming from a lamp or led is in fact an optic.. Parabolic reflectors are optics as well.
But indeed, in many cases, when someone refers to an optic, he (or she..) means an aspherical lens or one of those acrylic TIR-optics (Total Internal Reflection)
