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.
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.
One possible fanfiction could be set during a fight with some dark wizards in a back alley. Harry is outnumbered and gets beaten up badly. In the chaos, his glasses are knocked off and broken. He has to rely on his other senses and magic to fend off the attackers until help arrives.
Perhaps in the fanfiction, Harry is kidnapped by a powerful magical creature that has a vendetta against wizards. When it grabs Harry, his glasses are knocked off. The creature takes him to its underground den. Harry, without his glasses, is at a great disadvantage as he can't see well. But he remembers the magic within him. He tries to communicate with the creature using Parseltongue (if it's a snake - like creature). He hopes to either convince it to let him go or at least find his glasses so he can better defend himself and find a way back to Hogwarts.
Another idea is that some Death Eaters find Harry without his glasses in a vulnerable state. They start by taunting him about his weakness without the glasses. Then they use dark magic to make him experience extreme pain, like a searing pain in his eyes as if they are trying to make him feel the 'punishment' for relying so much on his glasses. They might also try to force him to perform difficult magic tasks without being able to see clearly, and punish him severely when he fails.
One possible plot could be that while kidnapped, Harry's lost glasses become a crucial element for his escape. Maybe the kidnappers don't realize the magical properties of the glasses and Harry uses a spell that is activated only when his glasses are in a certain state. For example, he could have a spell on them that when they are broken in a specific way, it sends a signal to his friends at Hogwarts.
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.
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.
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.
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.
Perhaps in the fanfiction, Harry discovers a new spell or a magical item that can temporarily enhance his vision without glasses. But there could be a catch, like it only works for a short time or has some side - effects. This would lead to a whole adventure of him trying to find a more permanent solution while also dealing with the normal challenges in the wizarding world.
