I only want eye tracking on my Index for VRChat integration so my avatar's eyes move with mine. I just cannot imagine using my eyes as some kind of input device, that sounds immensely awkward for someone that has more traditional options (i.e. no physical disabilities). I'm not using VR for productivity in any case, anyway.
