It works for me:Black eye bug, your character is too far away from the world center. Under Render Settings change Optimization > Instancing Optimization > Memory.
Surfaces tab > {your character's name} > Surfaces > Eye Moisture > Base > Refraction Weight. Probably defaulted to 1.00, reduce it. I've sometimes had the problem corrected if I reduce it even to 0.9999, sometimes you have to reduce it further.
