There could be a fanfic where Harry's glasses are replaced with a magical charm that gives him perfect vision. In this story, the charm might have some unexpected side effects that make his magical abilities even stronger. For example, he could see magical auras more clearly, which helps him in his Defense Against the Dark Arts classes.
A great fanfiction idea might be that Harry enters a parallel magical world where he was never born with the need for glasses. This would change his whole appearance and how others perceive him. He could make new friends who are drawn to this more confident version of him, and together they could uncover secrets about this alternate magical world.
One interesting fanfiction could be where Harry discovers a spell that temporarily changes his eyesight so he doesn't need glasses. This could lead to all sorts of new adventures as he no longer has to worry about his glasses getting broken during Quidditch or in a fight. He might even be able to use this new ability to his advantage in his battles against Voldemort.
One possible plot could be that without his glasses, Harry discovers he has a new magical ability related to his vision. Maybe he can see magical auras more clearly and it helps him in his fight against the dark forces. For example, he can easily detect hidden Death Eaters by the color of their auras.
One possible fanfiction could be where Harry loses his glasses during a crucial battle and has to rely on his other senses while glaring at the enemy. It might show his determination and inner strength even without the aid of his glasses.
A possible plot could involve Harry being forced to go without his glasses during a crucial part of a battle or a mission. Since he can't see clearly in the traditional sense, he taps into a latent magical ability that he didn't know he had. This new ability not only helps him in that situation but also changes the way he approaches magic in general. Also, perhaps a potion is spilled on his glasses and he has to go without them for a while, and during this time he meets a mysterious character who has a special connection to his lack of clear vision.
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.
One possibility could be that in this fanfiction, Harry's glasses are some sort of magical anchor. Without them, he might accidentally slip into a different dimension. Maybe he was in the middle of a battle at Hogwarts, his glasses got knocked off, and suddenly he vanished. It could be that the glasses were enchanted by Dumbledore long ago to keep Harry in the 'right' magical space, and without them, he's lost in a sort of limbo.
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.
One idea could be that in a magical accident, Harry's glasses are broken and he has to rely on his other senses and the help of his friends more than ever. For example, Hermione could use a spell to temporarily enhance his other senses. Another plot could involve a villain who targets Harry's glasses to disable him, leading to a race against time to get new ones or find a magical cure for his bad eyesight.
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.
Perhaps in this fanfiction, Harry is in a cage as part of a magical experiment. Some rogue wizards are trying to study how a wizard's magic is affected without their usual aids, like Harry's glasses. In the cage, Harry discovers new aspects of his magic that he didn't know before. He could start to manipulate the magical energy around him in different ways, even without clear vision, and eventually break free from the cage and confront those who put him there.
In this fanfiction, Harry without his glasses could be in a situation where he is forced to rely on his friends more when dealing with Horcruxes. His vision impairment without glasses makes it difficult for him to be as independent as he used to be. So, Hermione and Ron play a more crucial role. For example, when they are searching for a Horcrux in a dark and dangerous place, Harry has to trust their descriptions completely. And as they progress, Harry discovers that the Horcruxes are affecting his vision in a magical way, and he has to find a way to break this spell while still trying to destroy the Horcruxes.
