VR headsets do this. They are one of the most common applications due to how important tracking motion is, and also because they refresh at a higher rate by design - for content at lower refresh rates (60hz for a game) the flicker is very noticeable. If you've used an Oculus Go, some games run at only 60hz and the backlight flicker becomes quite noticeable.
If you do that and the eye is tracking (as in the context, here) then you get ghost images rather than blur, which is still quite distracting. That's the reason that a lot of films avoid mid-speed panning shots.

You can strobe at a higher rate than the refresh rate; IIRC film projectors would strobe at 72Hz with a frame rate of 24Hz.
