The conversations about Eichner's baby blues apparently spurred after he was spotted with a lazy right eye in season 6 of the NBC drama Parks and Recreation.
A Reddit thread based on the show's characters and storyline reported that the famed actor's right eye was droopy for the entire season.
But, interestingly, it wasn't visibly there when Eichner returned for season seven.
The Reddit user wondered if the actor made his appearance so deliberately, noting that Eichner didn't have such a look in real life.
The person guessed Eichner "did it as a sort of...metaphor, for one side being 'calm' and the other being 'intense'"
However, the user ended the topic by admitting they had no idea.

Another Reddit thread on the same topic encapsulated similar opinions. One internet user pinpointed he had seen many of Eichner's YouTube videos but never noticed the asymmetry.
"Maybe it's a new affliction," the person added. However, another follower suggested it could be an "over-exaggeration for the character."
While many of his fans believe Eichner faked the lazy eye in the show for his character, not everyone is on the same page.
Some netizens speculate that he might have a glass eye. And some even wonder if he suffers from horner syndrome, a nerve pathway disruption from the brain to the head that might cause drooping eyelids, among other symptoms.
That's because the comedian still had a lazy eye when he portrayed the role of Billy Epstein in the television series Difficult People.
And the appearance had everyone rushing to the internet to find out why he looked so.
A Twitter user wrote, "Not me googling, 'Why does Billy Eichner's eye look like that?'" on December 5, 2021.
Despite the burning curiosity, Eichner has never commented about his looks, neither confirming nor refuting the claims of him having a glass eye. Still, one can see the distinct differences between his two eyes—his right eye seems to move less and looks smaller than his left eye.
