It's kind of a thing.

Research shows that the "Japanese phenomenon" was a hoax made up by some reporters, but as far as I'm aware, eyeball licking fetish exists. It's just nowhere near as popular as some sources say (for click bait).

The concept is the same however; it's a show of affection that's more "advanced" than kissing. It's to show that Eto has an "attraction" to Kaneki by having her perform something that's not excessively sexual, but bizarre enough to make clear that her interest is not normal.
