Perhaps this is an obvious fact, but it has only reached me now. So many ghouls wear glasses because they can't wear contact lenses, their eyes are too sensitive
But what about hybrids? Here are some headcannons, let's go.
Eto. She wears glasses only when she is too lazy to insert lenses. By the way, she is absolutely comfortable with lenses. This girl won the genetic lottery.
Arima. In no case does he wear lenses. The most terrible allergy from which no medications help (in fact, it is not an allergy).
Hairu. She can wear lenses, but she is not comfortable in them. But she has pretty good eyesight to avoid using glasses/lenses most of the time.
Furuta. Before the operation, he could wear lenses (he used to mess with colored ones). He doesn't know yet that acquired lens intolerance together with Rize's kakuhou. If his eyesight deteriorates, he is more likely to prefer not to see anything than to wear glasses. He is too afraid to put on glasses and see in the mirror that he looks like Matsuri/Arima/Rize (he doesn't know which option is worse.
Amon doesn't know how to wear contact lenses, so when he became a ghoul, he didn't check if he could wear them. Likes glasses.
The craving for cosplay overcomes any intolerance to contact lenses in Saiko. However, she can wear them, just for a short time
Seidou has good eyesight, but he doesn't like the idea of shoving something in his eye, so no.
Urie wears lenses almost comfortably (he thinks that the quality of his favorite company has deteriorated and not his eyes have changed due to the fact that he is well a ghoul)
Shirazu wouldn't wear lenses because it's not cool, so he didn't even check.
Mutsuki didn't check either, but his eyesight is perfect.
Hsiao wears lenses. She is used to not paying attention to her discomfort, so she lives quietly with lenses.
Kurona had never thought about such things.
Kaneki... I think the canon would say that he can't wear lenses if he couldn't, because the canon clearly indicates what kaneki as a half-human can no longer do. He just needs glasses more (his mom wore glasses, his foster father wore glasses, his favorite author wore glasses). But perhaps in re he is more uncomfortable with lenses after Cochlea.
