архетип как меганекко

Personality-wise, Bespectacled Cuties [Meganekko] are sweet and affable by nature. Some are very friendly and trusting of other people, while others are painfully shy and prefer to fade into the background. As intelligence is often seen as a defining trait for such characters, they tend to double as Cute Bookworms. Sometimes the presence or absence of glasses shows a change in personality.

с смысловой точки зрения (хаха зрения) такая лёгкая модель бесполезна, ведь, опять же, они могут легко слететь, потеряться

если очки тут используются как элемент фансервиса

As glasses are fragile by nature and wearing them is normally (but not always) a sign of poor eyesight, they add an additional layer of vulnerability
