AI Technical Summary
Existing eyeglasses cannot meet the linear changes in refractive state of children and adolescents at different distances, leading to eye strain and increased myopia.
The infrared-controlled liquid glasses use a drive device to push the extrusion assembly to change the curvature and shape of the flexible film layer, and combine this with a distance sensor to detect the viewing distance, thereby achieving automatic adjustment of the lens diopter.
It meets the refractive power needs of patients at different distances, reduces eye strain and the risk of myopia progression, and achieves personalized refractive state design.

Abstract
Claims
1. An infrared self-regulating liquid eyewear, characterized in that: The device includes a frame (1), a lens (2) mounted on the frame (1), and a driving device (3). The surface of the lens (2) is provided with a deformable flexible film layer (4). There is a fluid chamber (5) between the flexible film layer (4) and the lens (2). The fluid chamber (5) is filled with fluid. Squeezing components (6) are provided on both sides of the fluid chamber (5). The driving device (3) drives the squeezing components (6) to squeeze or release the fluid in the fluid chamber (5) to change the curvature shape of the flexible film layer (4). An elastic sealing membrane (7) is provided between the squeezing components (6) and the fluid to isolate the squeezing components (6) from contact with the fluid.
2. An infrared self-regulating liquid lens according to claim 1, wherein: The opening edge of the fluid chamber (5) is provided with a sealing ring (8), and the elastic sealing membrane (7) contacts and cooperates with the sealing ring (8) to form a sealed space. 3. The liquid lens of claim 1, wherein: The front end of the frame (1) is provided with a distance sensor (9), which uses an infrared ranging module to detect changes in the distance to the target being gazed at by the user.
4. The liquid lens of claim 1, wherein: The extrusion assembly (6) includes an extrusion block (61) disposed on one side of the fluid chamber (5), and the end of the extrusion block (61) away from the fluid chamber (5) is connected to the drive device (3). 5. An infrared self-regulating liquid lens according to claim 4, characterized in that: A guide rail structure (10) is provided between the extrusion block (61) and the inner wall of the fluid chamber (5), and the guide rail structure (10) restricts the movement direction of the extrusion block (61).
6. The liquid lens of claim 1, wherein: The drive device (3) includes a small motor (31) installed in the frame (1), and the output shaft of the small motor (31) is connected to the extrusion block (61) of the extrusion assembly (6).
7. The liquid lens of claim 1, wherein: A storage battery (11) is provided inside the frame (1). The storage battery (11) is electrically connected to the drive device (3), the distance sensor (9) and the controller through wires to provide power.
8. The liquid lens of claim 1, wherein: The frame (1) is provided with a detachable cover (12) on the side, and the battery (11) can be removed and replaced through the opening of the cover (12).
