What do flirting eyes in dolls do?

Flirting eyes in dolls are designed to move side to side, simulating a playful or engaging expression. This design feature is often created to give the doll a lively appearance, making it more interactive and appealing to children. The mechanism allows the eyes to shift back and forth, which can enhance the storytelling experience during playtime by making the doll seem more animated and responsive. While other features like fixed positions or the ability to close and open eyes can be found in different types of dolls, the specific characteristic of "flirting eyes" refers to the smooth, side-to-side movement that evokes a sense of flirtation or charm.
