Boruto: Two Blue Vortex introduces a significant development in Sarada Uchiha's character, marking a transformative point. Especially considering her recent awakening of the Mangekyo Sharingan. This shows her growth and also inquires about how she could potentially attain the Eternal Mangekyo Sharingan. The unique circumstances of this awakening lie ahead with many possibilities.
The Uchiha clan's prowess is intensely embedded in a powerful visual ability known as Sharingan. This evolves through intense emotional experiences. The Mangekyo Sharingan, a heightened form, normally awakens via profound trauma. And this awakening is often linked to the loss of a loved one. Yet, Sarada's awakening deviates from this norm.
Sarada's Mangekyo Sharingan emerged not from grief but from a deep desire to protect Boruto. When Eida's Omnipotence ability converted reality, casting Boruto as a villain, Sarada stayed unaffected and realized the truth. In that situation, Sarada begs Sasuke, her father, to entrust Boruto. As such, her subsequent emotional unrest activated the awakening of her Mangekyo Sharingan.

In the recent chapter of Boruto: Two Blue Vortex, she finally displayed her Mangekyo abilities in battle. She created what seems to be a gravitational field that selectively absorbs specific targets.
Regardless of that, the Mangekyo Sharingan is a major handicap in the long run. Using it too much eventually causes blindness. This limitation has historically been overcome by attaining the Eternal Mangekyo Sharingan. It traditionally demands transplanting the eyes of a close blood relative.
But this traditional method of obtaining Eternal Mangekyo Sharingan isn't readily available to her. Sasuke, her father, only has one original eye left, and she has no siblings whose eyes she could use.
Potential Solutions of Sarada Uchiha for Obtaining Eternal Mangekyo Sharingan in Boruto

The Shin Uchiha clones introduced earlier in the series could provide a solution. These clones possess Sharingan and have bodies that don't reject transplants. While not directly blood-related to Sarada, the storyline could establish that their unique genetic makeup allows for compatible transplantation with minimal rejection.
The other possibility involves Hidari, who shares DNA with Sasuke. Though Hidari doesn't possess the Sharingan, his connection to Sasuke could provide an avenue for Sarada to obtain eyes compatible with her own. If Sarada were to defeat Hidari in Boruto, this could serve as an earned power-up rather than simply inheriting power.

Lastly, Sarada could follow her mother's footsteps by developing the Hundred Healings Seal (Byakugou). This powerful medical ninjutsu could potentially counteract the deterioration caused by Mangekyo overuse. This would be particularly fitting as it would incorporate aspects of both her parents' abilities, creating a unique power set.
Besides, she's the first Uchiha to awaken her Sharingan through optimistic feelings rather than trauma. This deviation from tradition proposes that the series might introduce entirely new ways for her to develop her ocular powers. Also, Sarada will need significant power-ups to remain relevant alongside strong characters who possess Karma.
The concluding part pulls Sarada Uchiha’s journey in Boruto into a transformative era for the clan. Her Mangekyo Sharingan, born from love and a desire to protect, challenges longstanding traditions. Whatever path she takes to achieve the Eternal Mangekyo Sharingan will likely reflect her unique position as an Uchiha born outside the cycle of hatred.
