Title:
AUTOMATICALLY ROTATING GLASSES
Document Type and Number:
WIPO Patent Application WO/2021/254450
Kind Code:
A1
Abstract:
Automatically rotating glasses comprise a frame formed by temples (3), a fixed rim (1), a rotatable rim (2), and a bridge (4). The fixed rim (1) and the rotatable rim (2) are hinge-connected to each other by means of an output shaft (9) driven by a micro motor (5) via a reducer (6), and a rotation shaft (10) coaxial with the output shaft (9). The micro motor (5) drives the output shaft (9) via the reducer (6) so as to rotate the rotatable rim (2). A lens (8) is mounted on the rotatable rim (2). The micro motor (5) is controlled by a controller (20). The controller (20) is automatically controlled by an infrared range sensor or a laser range sensor according to the distance to a viewed object, and if the distance exceeds a critical distance, the controller (20) is triggered to automatically control the micro motor (5) to rotate to drive the rotatable rim (2) and the lens (8) to rotate, such that lens switching is automatically performed for long distance viewing and short distance viewing during use. The invention is applicable to prevention and treatment of myopia, can be used as presbyopic glasses, and is also applicable to other scenarios requiring automatic lens switching.
