Abstract

A head-mounted device comprises a main body, a monitor-base, a monitor, and an adjusting component. The main body is mounted on a user's head. The monitor moves with the monitor-base. An eyes-monitor distance is defined between the user's eyes and the monitor. A visual range is defined by a range seen by the user's eyes through the monitor. The adjusting component is configured for pulling or pushing the monitor-base towards the user's eyes to prevent the eyes-monitor distance from increasing and to prevent the visual range from decreasing. When the user wears a pair of glasses between the user's eyes and the monitor, and the glasses block the monitor causing the eyes-monitor distance to be larger than a preset distance, the adjusting component pulls or pushes the monitor-base until the monitor contacts the glasses, to prevent the eyes-monitor distance from increasing. An augmented reality device is also disclosed.
