For the drama. It creates a sense of vulnerability for Harry. His glasses are an important part of his identity, and without them, he's at a disadvantage. This can heighten the tension in the story.
It could be a plot device to lead to new adventures or encounters. Maybe because he's without his glasses, he stumbles into a new part of the wizarding world he wouldn't have otherwise discovered. Or it could be a way to force him to interact with characters he might not have interacted with while having his glasses and being more in control.
One reason could be to explore the vulnerability of a character. In the 'Harry Potter' series, glasses are an important part of Harry's identity. By confiscating them, the writer can show a different side of the character, a more helpless side. It adds a new layer of depth to the character's story.
One possible scenario could be that he's being dragged by some dark magic force in a forbidden part of Hogwarts. Maybe he lost his glasses during a fight or while being chased, and now he's in a vulnerable state. Without his glasses, his vision is blurry, adding to the sense of danger and confusion.
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.
Well, some people might write it for shock value. They want to create something really out of the ordinary that will make readers go 'wow' or 'eww'.
In fanfiction, if Harry Potter were without glasses, it would likely have a significant impact on his character arc. His glasses are not just a visual accessory but also a symbol of his 'nerdy' or 'outsider' status at the start. Without them, he could be more integrated into the 'cool' crowd at Hogwarts. He might also be more daring in his adventures as he wouldn't have to worry about his glasses getting broken or lost during battles or dangerous situations. This could lead to a more confident and perhaps even a more flamboyant Harry Potter in the fan - created stories.
Some people might write it to explore a darker, more alternative take on the characters. They could be interested in seeing how the story would change if Dumbledore had a more sinister side. It's a way to break the established perception of the characters.
It could be a form of expressing a very different view of the Harry Potter universe. Some writers might feel constrained by the relatively positive and heroic nature of the original story and want to break free by creating something extremely contrasting. But this kind of fanfiction is likely to be frowned upon by many in the fandom. The original series has themes of love, friendship, and heroism, and this type of 'beaten to death' concept is a complete deviation from that. It might also be a result of the writer having some personal issues or a very different understanding of the characters and the world, but it's not a typical or welcome addition to the fanfiction landscape.
Perhaps they are fans of 'what - if' scenarios. In the original books, Harry marries Ginny. But by writing him with Fleur, they can create alternate storylines that deviate from the canon. This can be exciting for both the writer and the readers who enjoy exploring new and unexpected plot directions in the beloved Harry Potter world.
In fanfiction, without his glasses, Harry Potter might be seen as more vulnerable. His glasses are like a part of his identity, and without them, he may struggle more with seeing clearly, which could add an interesting layer to his character, like when he's in a dangerous situation and his blurry vision could lead to some unexpected plot twists.
A fanfiction idea could be that without his glasses, Harry's world becomes a bit of a blur. He starts to rely more on his other senses. In the Forbidden Forest, this could be both dangerous and enlightening. He might be more attuned to the sounds and smells of the forest, but at the same time, he could easily walk into a dangerous area. His friends, Hermione and Ron, would have to be extra vigilant in protecting him. This new dynamic could change the relationships between them and lead to new adventures.
