Jōgan

This dōjutsu was awoken by Boruto Uzumaki in his right eye. In the manga, this dōjutsu is featureless in appearance with a barely visible pupil. When depicted in the anime, the dōjutsu is blue in colour with a darkened sclera and visible pupil.

When first used during his time in the Academy, Boruto did not appear to have the ability to activate it on command, instead the eye would involuntarily activate when Boruto focused his attention on a particular person or object. As a teenager, he displayed the ability to activate it at will.

Abilities
Before seemingly gaining control of this dōjutsu, it would independently activate in the presence of dangerous/hidden targets. It can perceive the flow of chakra, enabling Boruto to see the visible changes in one's chakra and likewise track a target through their chakra. It can clearly see the chakra pathway system, determine its most key point. It can also see through invisible barriers that connect between dimensions.

Trivia
He also explained that the eye is related to the Ōtsutsuki clan's dimension and its powers are a combination of the Byakugan's abilities and Naruto's Negative Emotions Sensing, but noted that all this information would be explained in detail in the future and fans should not think too much of it for now.
 * One of the animators of Boruto: Naruto Next Generations posted a picture on his blog that shows Boruto cleaning his right eye. The caption of the picture reads and in the accompanying text, the animator elaborated that Boruto's eye was neither a Byakugan nor a Tenseigan, but officially called "Jōgan".
