Paragraph about how Harry Potter's glasses are represented throughout the movie:
Harry Potter's glasses are one of the most visible things about his appearance in the movies. He is blind without them. One way his glasses are represented throughout the movie is his smart abilities. Although he may not be a crazy study-person like Hermione Granger, he is undeniably smart. If you don't think so, then take a look at this: he was The Chosen One that had to take down Voldemort and not any dumb kid could pull that off. Another way his glasses are represented throughout the movies is by a very powerful character trait; creativity. Creativity is shown by his glasses because he used them as an advantage in his Quidditch match one time when it was raining very hard and he needed to repel water away from his eyes so he could more easily see the Snitch (Hermione used the Impervius Charm). Who would've thought you could repel water using your own glasses? Lastly, his glasses show that his father, James Potter, also wore glasses, as he too had problems seeing.
Paragraph about how the glasses symbolize school:
One way Harry Potter's glasses symbolize school is they show anyone can be smart. Harry was not the top of his class, though he was famous. However, he is undeniably a smart kid. Another way Harry's glasses symbolize school is because of this neat idiom: "four eyes". This represents many things. For example, it could represent that one is very aware of what is going on in school. Lastly, Harry's glasses show that one must keep moving forward in school. You can connect to this from a clip in the movie, when Harry lost his glasses at the Whomping Willow, but had to keep moving forward into the Whillow in order to catch up to Ron Weasley. (Harry did get his glasses in the movie clip before he entered the tree, of course).
Hope this really helps you out! :)
