Are you using mods/cc in your game ? If so, please remove them
See this for more information: [PLEASE READ] Usage of Mods and Custom Content
The same happens to me!
I tried repairing the game, and it didnt work
then i moved the mods folder to desktop and started the game to see if the bug was still there and it was gone! 🙂
But the thing is i like my mods, so then i tried moving The Sims 4 folder to desktop, started the game to make new folder in documents,
and then moved all of my saved files an mods back, and it still didnt work :/
Mods get outdated with patches and need updating.
It's probably some eye replacement that either needs updating (check with the creator) or removing.
You could easily download contact lenses cc online! I suggest meteor eyes as they aren't too creepy looking and are absolutely beautiful. Download the face paint versions for children (they work on both toddlers and children), or you could also download the adult version as well. I don't suggest the non default version as they tend to switch back to the vampire eyes. This issue has come across me as well, so you could use these eyes (or any other) while waiting for EA to release a patch.
