Agreed on Hair but honestly the "Baked in" reflections
,on well done photo based eyes ,work for me most of the time under most lighting conditions

But still the aforementioned merchant "Shaharra" was kind enough to provide versions of his eye mat poses without the baked in reflections as well, for those who wish to use actual ray traced reflections from their scene environment,

True, they can look okay if your lighting is just right--but that does constrain the lighting you can do. If you set your eye shaders up right (the ones BB posted recently work fantastic) and set up a proper scene--either with a full set off camera or an HDRI--the reflections will be more realistic and non-scene dependent.
