Fluorite and flouride are two different things. In fact, you'll likely never see fluorite in binocular lenses. Flourite's main purpose is to further reduce chromatic aberration on optics with longer inter-lens distances and is therefore all but useless in binoculars.
Zeiss has been using flouride lenses and coatings for decades with great success. I also prefer their 3-reflection Abbé-Koenig prisms with achromatic lenses which makes for a stunning picture with no rolling-ball effect along with the best edge-to-edge uniformity.

Most others HD manufacturers including Swarovski use the Schmidt-Pechan prism with 5 reflections plus air gap.

They also grind their lenses for more of a "sweet spot" which can affect the view when panning, especially in complex terrain such as trees. Have a look through a Swarovski, especially their scopes, while panning and see if you notice that rolling-ball effect. I find it a little distracting and unreal looking.
I believe Zeiss optics use the best, most natural looking lens setup for a hunting binocular.
