When this option is enabled, the Facing Color intensity is corrected to better match the computed Fresnel reflectivity, for more realistic results.

This shader node computes a Fresnel effect weighted color. The Fresnel effect determines how the reflectivity of a surface changes when an incident ray is parallel vs perpendicular to the surface normal, with the reflectivity being strongest when perpendicular. This node is useful for effects such as controlling color ramps that change with viewing angle or blending material reflection layers in a physically correct way.

Above shows an example of the 'Fresnel effect' of facing reflectivity vs perpendicular reflectivity, tinted green to highlight the effect

When Use Index of Refraction is disabled, this option controls the shape of the Fresnel fall-off curve as it transitions between the Facing Color and the Perpendicular Color.

This allows you to toggle between a cheap Schlick Fresnel computation that does not require an Index of Refraction and a more complex, but more correct, method that does.

When Use Index of Refraction is enabled, this is the value that describes the index of refraction. For non-metals, the facing Fresnel reflectivity is pretty dim and this value should be between 1.0 and 2.0.
