It could slow down the plot. For instance, if Harry's glasses are constantly malfunctioning, he might miss important clues or signals. This would add more obstacles to his journey of solving mysteries or fighting against the dark forces.
In this fanfiction, his glasses could have a disorder where they constantly fog up, no matter the temperature or humidity. It would be really annoying for Harry. He might be in the middle of a battle with Death Eaters or trying to solve a mystery in Hogwarts, and he has to keep wiping his glasses to see clearly.
His relationship with Hermione might change. Hermione would probably be more protective and try to help him find a solution to his 'without glasses disorder'. She might also be a bit more bossy as she tries to guide him around since he can't see well.
Family relationships are explored too. If it's a Weasley with an eating disorder, the large and close - knit Weasley family would be deeply concerned. Molly Weasley might try to force - feed the character in a well - meaning but perhaps misguided way, while Arthur might be more at a loss about how to handle it, showing the different ways family members react to such a difficult situation.
Harry might become withdrawn and introverted. Feeling unloved and unwanted, he could start to keep to himself more, spending time alone in his room or exploring the grounds of their home alone, trying to make sense of why his parents seem to favor the twins.
The 'last will' can also create conflicts. If multiple characters are named in a will, they might fight over the inheritance, whether it's a physical item, a property, or knowledge. This conflict can be between friends or enemies. For example, two houses in the wizarding world might battle over a powerful spellbook left in a will, which then spreads the conflict to other characters and events in the story, greatly affecting the overall plot development.
He might become withdrawn. Feeling unloved and ignored, Harry could start to keep to himself more, not sharing his thoughts and feelings with his family. He may also become resentful towards the twins, seeing them as the cause of his being neglected, even if it's not entirely their fault.
The loss of Harry's glasses might create a vulnerability that Shacklebolt has to address. It could be a starting point for a new adventure or a plot twist. Maybe it makes Harry more reliant on others, like Shacklebolt, which changes the power dynamics in their relationship.
Well, it would definitely make it harder for him to see clearly in classes. He might struggle to read the blackboard or follow along in his textbooks, which could affect his grades.
In fanfiction, Harry's understanding of the Potters can expand. He might see his parents as more complex characters. For instance, if a fanfic shows James Potter as having a struggle with a certain type of magic, it makes him more than just the heroic figure Harry knew. This changes Harry's view of his father.
In a fanfiction, if Harry Potter loses his glasses, the plot will likely take a different turn. His lack of clear vision could make him seem less confident, which would change how others perceive him. Enemies might underestimate him, giving him an opportunity to surprise them. His search for a replacement or a solution to his vision problem could introduce new characters, like an old wizard who specializes in eye - related magic, and new sub - plots could unfold as a result.
