A pair of intelligent color-changing eyeglasses (100) comprises a frame (1). The intelligent color-changing eyeglasses (100) further comprises a color-changing lens (4), a control device (5), and a light-emitting device (6). The control device (5) and the light-emitting device (6) are arranged in the frame (1), and the frame (1) surrounds the edge of the color-changing lens (4) to fix the color-changing lens (4). The control device (5) is electrically connected to the light-emitting device (6), to control the light-emitting device (6) to emit light. The light-emitting device (6) is used to emit light onto the color-changing lens (4) to cause color-changing of the color-changing lens (4). By using the light-emitting device (6) to emit light onto the color-changing lens (4) to actively change the color of the color-changing lens (4), the intelligent color-changing eyeglasses (100) can prevent strong sunlight from being shone into the eyes before a user goes outside. Moreover, by using a defogging device (3) to remove fog on the color-changing lens (4), the present invention effectively avoids blurry eyeglasses caused by fog.
A: An in vitro diagnostic analysis system, and an optical detection apparatus. The optical detection apparatus comprises a lens module (10), a light source module (20), a detection module (30) and a driver. The lens module (10) comprises a first mounting unit (100), a dichroscope (200), an excitation sheet (300) and an emission sheet (400), wherein the dichroscope (200) and the excitation sheet (300) are arranged, spaced apart from each other, on the first mounting unit (100), and the dichroscope matches the excitation sheet (300) to form an excitation light path; and the dichroscope (200) and the emission sheet (400) are arranged, spaced apart from each other, on the first mounting unit (100), and the dichroscope matches the emission sheet (400) to form an emission light path. The light source module (20) comprises a second mounting unit (22) and a light-emitting member (24), wherein the light-emitting member (24) is arranged on the second mounting unit (22), and the light-emitting member (24) and the excitation sheet (300) are arranged spaced apart from each other. The detection module (30) comprises a third mounting unit (32) and a detection element (34), wherein the detection element (34) is arranged on the third mounting unit (32), and the detection element (34) and the emission sheet (400) are arranged spaced apart from each other. The driver is used for driving the first mounting unit (100) to move.
B: Provided are a photochromic lens comprising a lens (10) and a photochromic thin film (20). The lens (10) comprises a first face (101) and a second face (102). When the first face (101) is an incident face, the second face (102) is a refractive face, and when the second face (102) is an incident face, the first face (101) is a refractive face. The photochromic thin film (20) comprises a first region (201) and a second region (202). The photochromic thin film covers the first face (101) or the second face (102). The first region (201) uses a negative photochromic material, and the second region (202) uses a positive photochromic material. Also provided are a camera comprising a photochromic lens and a terminal device comprising a camera.
C: A novel coated optical lens, comprising a lens (2), wherein one side of the lens (2) located at a surface of a convex surface is provided with a protective layer (9), and the protective layer (9) is composed of a color-changing film (5), an anti-wear film coating (6), an anti-radiation film (7), and a waterproof and dustproof film (8). The color-changing film (5) covers a surface of the anti-wear film coating (6), and the anti-wear film coating (6) is provided at a surface of the lens (2). A surface of the color-changing film (5) opposite to the anti-wear film coating (6) is covered with the anti-radiation film (7). By means of disposing the protective layer (9) composed of the color-changing film (5), the anti-wear film coating (6), the anti-radiation film (7), and the waterproof and dustproof film (8) on a surface of the lens (2), when the lens (2) is being used, the influence of indoor and outdoor light intensity on the lens (2) may be mitigated under the action of the color-changing film (5), and the abrasion resistance may be increased under the action of the anti-wear film coating (6). Under the action of the waterproof and dustproof film (8), water spots may be made to flow to the lens (2) and then quickly drain off, thereby reducing staying time.
D: A pair of dimmable glasses having Bluetooth headphone functionality. The pair of dimmable glasses comprises a glasses frame (100), a dimmable lens (200), a control apparatus, and Bluetooth headphones (300); the dimmable lens (200) is arranged on a rim (110) of the glasses frame (100); the control apparatus comprises a control circuit board and a power-providing battery electrically connected to the control circuit board which are arranged on a temple (120) of the glasses frame (100); the Bluetooth headphones (300) are arranged on the temples (120) and are electrically connected to the control circuit board; the dimmable lens (200) is either a photochromic lens (220) or a liquid crystal lens (210) electrically connected to the control circuit board. The pair of dimmable glasses having Bluetooth headphone functionality has the capability to dim and undim the lens according to the intensity of light in the environment, and as such can effectively protect human vision.
