Sunglasses have long been symbols of coolness and attractiveness, and research explains why. Sunglasses enhance facial symmetry by covering asymmetrical features around the eyes, which is often linked to beauty. Additionally, they create an air of mystery by obscuring the eyes, making the wearer seem more intriguing and leading to positive snap judgments about their intelligence, confidence, and sincerity. Moreover, people in sunglasses are often perceived as more stoic and less expressive, adding to their composed and cool image.
