I usually point out that even though they can see everything that's not the same as presenting an avenue for visual genjutsu to flow into their eyeballs. Otherwise, sensor nin like Karen with her Mind's Eye of the Kagura would be susceptible to visual genjutsu from 10 Km away without the caster even being aware of it.

Closed eyes on a Hyūga should prove very effective against Sharingan and other visual genjutsu attacks, like Ephemeral. Kishi really should've addressed this, but he chose not to. Karin's Mind's Eye of the Kagura isn't actual sight like the Byakugan's field of view. A better comparison to the Byakugan's field of view would be Gaara's and Rasa's Third Eye since both involve actual sight.
