You've asked about Lightroom CC but posted in the Lightroom Classic CC forum. Two totally different software apps.
I assume you're using Classic CC.
There's a Red Eye Correction Tool in the Classic CC Develop module.
In Lightroom Classic CC you use a Red-Eye Tool in Develop Module
There is no red eye reduction available in Lightroom CC. As already said, in Classic you can do it (albeit very poorly), but not in Lightroom CC. If you need it, go to Lightroom CC: Please add red eye removal | Photoshop Family Customer Community and add your vote/comment.
I should imagine this is something Adobe will add to LRCC in a future update. Artificial intelligence based upon millions of machine learning data sets could possibly fix red eye automatically.
Indeed. It knows already how to find faces (although it has to do this in the cloud) and should be able to automatically detect the eyes and place a red eye target on them.
