It could be that the glasses represent more than just a visual aid for Harry. Maybe they are a symbol of his identity as 'Harry Potter, the Boy Who Lived'. In the fanfiction, the realization might be part of a deeper exploration of how his appearance and the items associated with it are intertwined with his destiny. For example, his glasses could be a connection to his past, perhaps having some magical origin or significance that he was previously unaware of.
Another plot development could be related to his family. Harry might find out that the glasses were passed down from his parents or some other important family member, and there is a family secret or power associated with them. This could involve a quest to learn more about his family's past and the true nature of the glasses, which could put him in conflict with some dark forces that don't want him to uncover the truth.
In many fanfictions, Harry Potter's glasses play an important role. Some might explore how his need for glasses affects his magical abilities. For example, a fanfic could have a plot where a spell goes wrong because his glasses were broken, leading to a series of comical or dangerous situations. It could also be a part of his identity in the fanfic world, like other characters recognizing him mainly by his glasses.
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.
It could be that Harry's glasses disappear as a result of a magical experiment gone wrong. For example, Hermione might be trying out a new spell she read about in an ancient book, and it backfires, causing Harry's glasses to vanish. This would create a bit of a rift between them at first, but they would soon realize that they need to work together to reverse the spell and retrieve the glasses.
There could be a fanfiction where Harry is studying in the library with his broken glasses. He's squinting hard to read the old, faded texts. Hermione notices and offers to help him fix his glasses with a spell she's been researching. But Harry refuses at first, wanting to do it on his own. This creates a bit of tension between them, and as they argue, Ron comes in and tries to mediate. It could be a comical and character - driven fanfiction scenario.
There could be a fanfiction where Harry discovers the blindfolded glasses in an old, dusty corner of the Room of Requirement. When he puts them on, he's transported into a different dimension within Hogwarts where everything is a mystery. He has to use the limited vision through the glasses (maybe they have some sort of enchanted sight) to figure out how to get back to his own Hogwarts while also uncovering secrets about the castle's past.
