Flicker fusion is the ability to distinguish many separate flashes of light simultaneously.

Flying inscets and humans, both have the ability of flicker fusion and it provides them to give a better visual of a fast-moving objects. Though humans have less flicker fusion threshold than insects.

They both can change their flicker fusion threshold as a function of viewing stimulus size, distance, luminance, intensity, achromatic vs. chromatic, and retinal location.
