Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a photochromic lens and a manufacturing method thereof, which solves the problem that when the lens is used at high speed and suddenly enters a tunnel from a strong light environment, due to the light transmittance of the lens at this time, In addition, the tunnel environment itself is relatively dark, which can easily cause a greater impact on the driver's sight, and even cause major traffic accidents in severe cases. Therefore, there are certain safety hazards in the actual application process.

Embodiment 1

[0035] like Figure 1-3 As shown, the embodiment of the present invention provides a photochromic lens, which includes a photochromic lens body 2 installed in the center of the lens frame 1, and the photochromic lens body 2 is fitted and fixed to the inner wall of the lens frame 1, which can not only realize a tight connection and fixation , it can also be quickly replaced when the photochromic lens body 2 is broken or damaged; the photochromic lens body 2 is a flat lens, by using a flat lens, it will not affect the function and characteristics of normal glasses, but also can play a normal color changing effect;

[0036] The two sides of the inner surface of the lens frame 1 are respectively provided with a first magnetic strip 3 and a second magnetic strip 4; the first magnetic strip 3 and the second magnetic strip 4 are bonded and fixed with the lens frame 1, and the first magnetic strip The strip 3 and the second magnetic strip 4 are fixed on the inner side of the lens fram...

Embodiment 2

[0045] like Figure 4 As shown, this embodiment is based on the first embodiment: the lens frame 1 is made of a magnetic metal material, and the photochromic lens body 2 is fitted and fixed to the inner wall of the lens frame 1. When in use, it can be directly adsorbed and positioned on the metal frame. .

[0046] The specific steps of the production method of the photochromic lens are as follows:

[0047] S201. According to the size and structure of the mirror frame, use a casting mold and a magnetic metal material to cast a magnetic lens frame 1, remove surface burrs and excess waste after demolding, and polish the surface of the lens frame 1;

[0048] S202. Cut the photochromic lens raw material into the photochromic lens body 2;

[0049]S203. Fit the photochromic lens body 2 after cutting in S202 to the inner wall of the lens frame 1 in S201.

Embodiment 3

[0051] like Figure 5 As shown, this embodiment is based on the first embodiment: the center of the top of the lens frame 1 is fixedly connected with a positioning cover plate 7, the positioning cover plate 7 is a detachable structure, the upper frame is made of plastic material, and the lower frame is made of metal material By fixing and connecting the positioning cover 7 at the center of the top of the lens frame 1, the upper part of the lens can be hung on the top of the plastic frame, while the middle and lower parts of the lens are still attached to the metal frame.

[0052] The specific steps of the production method of the photochromic lens are as follows:

[0053] S301. According to the size and structure of the mirror frame, design a corresponding casting mold, use the casting mold to cast the lens frame 1, remove the surface burrs and excess waste after demolding, and polish the surface of the lens frame 1;

[0054] S302. Cut the photochromic lens raw material into ...

Abstract

The invention provides a photochromic lens and a manufacturing method thereof, and relates to the technical field of lenses. According to the photochromic lens and the manufacturing method thereof, the photochromic lens comprises a photochromic lens body installed in the center of a lens frame, the photochromic lens body is embedded and fixed to the inner wall of the lens frame, the photochromic lens body is a plano lens, and a first magnetic attraction strip and a second magnetic attraction strip are arranged on the two sides of the inner surface of the lens frame respectively; the first magnetic strip and the second magnetic strip are bonded and fixed with the lens frame; a top groove and a bottom groove are respectively formed in the top and the bottom of the inner surface of the lens frame; the center of the top of the lens frame is fixedly connected with a positioning cover plate. By designing the detachable photochromic lenses, the photochromic lenses can be combined with the glasses frame for use under normal conditions without being detached, and when a user suddenly enters a dark environment, the photochromic lenses can be quickly taken down by a single hand in an extremely short time, so that the visual line of the user or a driver is prevented from being greatly influenced, and the potential safety hazard is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a photochromic lens and a manufacturing method thereof. Background technique [0002] Photochromic lenses are lenses that become dark when exposed to light of a certain wavelength (usually ultraviolet light), and return to their original transmittance when they are no longer illuminated by the light source. Clear; photochromic lenses can be made of glass or plastics including polycarbonate, and the color-changing effect is caused by the addition of silver chloride or other halide to the lens, which when not exposed to UV light It is transparent to visible light. When it is irradiated by ultraviolet light, it will react chemically. After the chemical reaction, it will absorb part of the visible light and make the lens appear dark. This chemical reaction is reversible, so the lens will return to its original transparent state when it is no longer exposed to UV light. [0003] Phot...
