I'm not entirely sure what specific situation you're referring to. In the Harry Potter series, Harry is the one who wears glasses, and he has his own share of hardships but not in a context of 'tortured and puts glasses on' in the original. In fanfiction, this could be some really out - of - the - box or dark interpretation where perhaps an author has created a scenario where Harry is tortured and then his glasses are put on him in a cruel or strange way. But without more context, it's hard to say exactly.
I'm not aware of any extremely famous fanfiction with that exact plot. There are thousands of Harry Potter fanfictions out there, but this seems like a rather specific and somewhat dark concept that may not be as widespread in well - known fanfictions. However, it's possible that there are some niche or more adult - themed fanfictions with this idea, but I can't recommend those as they might not be appropriate.
A fanfiction might have it that a new dark force in the wizarding world targets Harry. They manage to trap him in an old, abandoned manor. They torture him using various dark spells, and during the chaos, his glasses are lost. Harry endures the pain and tries to remember some of the spells Hermione taught him for self - defense. Eventually, he breaks free from his bindings and starts looking for his glasses. He stumbles around the manor, using his wand light to search, while also being on the lookout for the return of his captors.
Well, it could start with Harry being lured into a trap by some mysterious enemies. They might be after the secrets of Dumbledore's Army or something. Once trapped, they start torturing him. His glasses could be lost when he's thrown around during the torture. Then, he might use his magical skills, like his ability to communicate with snakes (which he has from being a Parselmouth), to call for help or find a way to escape. He'd be at a disadvantage without his glasses, but his determination would keep him going.
Maybe in this fanfiction, the island is a place filled with illusions. Harry's lost glasses are not just ordinary glasses but hold some sort of key or magic. As he tries to find them, he discovers secrets about the island and its connection to his past. For example, the island might have been a place where a powerful wizard once hid something important, and Harry's glasses are somehow related to it. He has to use his wits and magic skills to overcome the illusions and find his glasses before it's too late.
Well, it might be about Harry losing his glasses on an unknown island. Maybe he has to search for them while facing magical creatures and challenges specific to that island. It could also involve his friends helping him out, and in the process, they discover some long - lost secrets of the island.
One such fanfiction could be 'The Dark Trials of Harry Potter'. In this story, Harry endures intense torture by dark wizards which causes him to lose his glasses. It shows his struggle to survive without his vision aid while facing the evils. However, such fanfictions often deviate from the original J.K. Rowling's vision, but they can be interesting to explore different aspects of the characters.
Obviously, Harry Potter would be the main character as it's in his name. Hermione and Ron might also be there to help him find his lost glasses. They could use their combined knowledge and skills to explore the island.
Perhaps a magical creature that has made the island its territory. This creature doesn't want outsiders like Harry and his friends interfering. It sees Harry's glasses as a strange and foreign object and will do anything to keep them from leaving the island. It could be a giant spider - like creature that spins webs to trap intruders, just like the acromantulas in the Harry Potter series.
Harry might initially be in a state of shock. He has always been able to rely on his glasses to see, and without them, the world is a blur while he's being tortured. This could make him angry too. He might lash out blindly, trying to cast spells in the direction he thinks his enemies are, even if he's not sure. And as the torture continues, he could become more determined to resist, using his strong willpower to endure the pain and fight back in whatever way he can.
