Well, in some fanfictions, it could be through a powerful magic spell cast by a very skilled wizard. Maybe Dumbledore left behind a special spell in his old notes that Hermione discovers and uses on Harry.
Another possibility is that Harry's own inner magic somehow mutates or evolves. Due to all the powerful magic he has been exposed to over the years, his body starts to adapt and his eyesight is restored as a result. His connection with Voldemort's magic might also play a role. When Voldemort was defeated, some of the dark magic that had affected Harry in a negative way was reversed, and this could include the restoration of his sight.
In certain fanfic scenarios, it might be related to some ancient magic artifact. For example, there could be a magical amulet that has the power to heal any kind of injury, including restoring eyesight. Harry might find this amulet during one of his adventures in a hidden chamber in Hogwarts. He touches it and suddenly can see again.
In Sequence 1, Wei Yuan had regained his vision through Ren Xiaosu's ability. In order to save Yan Liuyuan, Ren Xiaosu chose to use " Command of Law " on Wei Yuan. As a result, Wei Yuan regained his vision. While waiting for the TV series, you can also click on the link below to read the classic original work of "Dafeng Nightwatchman"!
He could regain it through the support of his friends. If Hermione and Ron show him unconditional love and support, and remind him of all the good he has done and all the people he has saved. Their friendship has always been a strong bond in his life, and it can be the key to bringing him back from the brink. Also, if new friendships are formed, like with some previously overlooked characters who offer him new perspectives on life.
There might also be some new or minor characters from the wizarding world that are introduced specifically for this fanfiction. For instance, an old healer who has a unique method of restoring eyesight that no one else knows about. This character could play a crucial role in Harry being able to see again.
Maybe he was in sudden pain. It could be due to a spell that backfired on him and affected his diaphragm area, causing him to clutch it instinctively for relief.
Well, in Harry Potter fanfiction, 'in plain sight' could refer to many things. It might be about magic items or characters that are hidden yet somehow still visible in a sense. For example, the Marauder's Map shows people's locations in Hogwarts which are, in a way, in plain sight but only to those who know how to use the map.
He could find a new purpose. Maybe he starts to focus on helping the younger generation of wizards, teaching them how to defend themselves. This gives him a sense of hope for the future and reignites his will to live.
He could start by having an honest conversation. Just sitting down with his friends and explaining his side of the story, whatever it may be. Clear communication is often the first step in mending relationships.
Often through the creative interpretations of the fanfiction writer. They might give him a special spell or charm that enables him to see magic.
Well, it could make his relationships more complex. For example, if he sees a dark aura around someone, he might be more cautious. But if it's a bright, friendly aura, he could be more trusting. This ability would give him an extra sense when dealing with friends and foes alike.
The plot could progress with Harry using magic to compensate for his lack of glasses. For example, he could use a spell to make his eyesight better. Or, his friends could use their skills to help him. Hermione might use a spell to locate his glasses in the chaos of the brawl.
