一种调光镜片及防控眼镜
By setting a dimming film of liquid crystal/polymer hybrid material on the lens, the contrast can be adjusted by switching on and off the power, which solves the problem of fixed contrast in existing myopia control lenses, improves the myopia control effect and ensures visibility.

AI Technical Summary
The contrast of existing myopia control lenses cannot be adjusted according to changes in ambient light, resulting in poor myopia control effects.
The dimming film, which uses a liquid crystal/polymer hybrid material, adjusts the contrast by switching on and off, and achieves automatic adjustment in conjunction with a light sensor and control unit.
It achieves dynamic adjustment of lens contrast, improves myopia control, and maintains a certain light transmittance in a semi-transparent state to ensure visibility.

Abstract
Claims
1. A light-adjustable lens, characterized by: The device includes a lens body having two opposing surfaces, at least one of which is covered with a dimming film. The dimming film is made of a liquid crystal / polymer hybrid material and is electrically connected to a power supply. As the dimming film is switched on and off, the liquid crystal molecules in the dimming film switch between a regular arrangement and a disordered arrangement, and the dimming film changes to a transparent state or a semi-transparent state, thereby changing the contrast of the dimming lens.
2. The light-adjustable lens of claim 1, wherein: The lens body is a single-layer lens structure, and the dimming film is provided on both surfaces of the lens body.
3. The light-adjustable lens of claim 1, wherein: The lens body has a double-layer lens structure, and the dimming film is disposed in the middle layer of the lens body.
4. A dimming lens according to claim 1, characterized in that: The dimming film has multiple light-transmitting holes; the light-transmitting holes are filled with a transparent material.
5. A light control lens according to claim 4, wherein: The light-transmitting holes are divided into a central light-transmitting hole and peripheral light-transmitting holes. The central light-transmitting hole is located in the central area of the dimming film, and the peripheral light-transmitting holes are distributed around the central light-transmitting hole.
6. The light-adjustable lens of claim 1, wherein: The dimming film is adhered to the surface of the lens body.
7. The light-adjustable lens of claim 1, wherein: The lens body is a transparent resin lens or glass lens. The dimming film is used to make the liquid crystal molecules inside it arrange in an orderly manner to form a transparent state when the power is on. The dimming film is also used to make the liquid crystal molecules inside it arrange in a disordered manner to form a semi-transparent state when the power is off.
8. The light-adjustable lens of claim 1, wherein: It also includes a light sensor and a control unit. The light sensor is used to detect the brightness of the environment in which the dimming lens is located, and the control unit is used to adjust the on / off state of the dimming film according to the brightness detected by the light sensor.
9. A control eyeglass, characterized by: It has a dimming lens as described in any one of claims 1-8.
