Description

Indoor usable polarisation sunglasses that discolours

Technical Field

The utility model relates to a sunglasses especially indicates an indoor usable polarisation sunglasses that discolours.

Background

People who need to wear glasses in daily life, such as myopia, often cannot wear ordinary sunglasses directly, so that the people can wear the sunglasses by selecting the color-changing glasses. However, the common color-changing glasses can still block light when being used indoors, so that objects become dark and the eyesight fatigue is easily caused, therefore, the glasses are not suitable for people suffering from glaucoma, myopia and astigmatism or high myopia, and the like, and can also influence the common myopia people.

On the other hand, as a polarizer commonly used in sunglasses, it is also difficult to see objects indoors, and especially when facing a screen, rainbow stripes are generated, which makes it impossible to use electronic products such as mobile phones and computers, and is not suitable for indoor wearing.

The indoor usable color-changing polarized sunglasses comprise a sunglass frame, two sunglass legs and two lenses, wherein the lenses comprise substrates, the substrates are made of transparent materials, and the outer surfaces of the substrates are provided with a layer of photochromic coating and an anti-ultraviolet coating from inside to outside; the picture frame is in all be provided with a receiver above two lenses, be provided with the pivot in this receiver, be fixed with a flexible polaroid in this pivot, the pivot drives when rotatory flexible polaroid curls or stretches out.

Further, the both ends of pivot are all fixed in the bearing, the bearing is fixed in the receiver.

Furthermore, one end of the rotating shaft extends out of the storage box and forms a roller.

Further, the surface of the roller is provided with convex teeth.

Further, the substrate is made of an acrylic material.

Further, the photochromic coating is formed by adding photochromic factors into the polyurethane solution.

Further, the flexible polarizing plate is a plastic film attached with a polarizing film.

(III) advantageous effects

Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, utilize the transparent lens with photochromic coating and the flexible polaroid that can accomodate to block visible light and ultraviolet ray simultaneously, be fit for outdoor use, photochromic coating is less to glasses luminousness influence simultaneously, and flexible polaroid can be accomodate, is fit for indoor place and uses electronic screen.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and 2, a pair of color-changing polarized sunglasses usable indoors includes a frame 1, two legs 2 and two lenses 3, wherein the lenses 3 include a substrate, the substrate is made of a transparent material, specifically, the substrate is made of an acrylic material or transparent glass, and a photochromic coating and an ultraviolet-proof coating are disposed on the outer surface of the substrate from inside to outside;

in order to prevent the photochromic coating from affecting the transmittance of the lens 3 in dark places such as indoors, the thickness of the photochromic coating needs to be controlled to be less than 20 μm, and thus the ultraviolet protection capability needs to be enhanced. For this reason, the lens frame 1 is provided with a storage box 4 above the two lenses 3, a rotating shaft 41 is arranged in the storage box 4, a flexible polarizing film 5 is fixed on the rotating shaft 41, specifically, the flexible polarizing film 5 is a plastic flexible film with a polarizing film, which is convenient to store and does not scratch the lenses 3, and the rotating shaft 41 drives the flexible polarizing film 5 to curl or stretch when rotating.

In order to make the rotating shaft 41 rotate smoothly, both ends of the rotating shaft 41 are fixed in bearings 42, and the bearings 42 are fixed in the storage box 4.

In order to adjust the rotating shaft 41, the flexible polaroid 5 is folded and unfolded, and one end of the rotating shaft 41 extends out of the storage box 4 to form a roller 42; further, in order to prevent the control shaft 43 from slipping and being difficult to control, the surface of the roller 42 is provided with convex teeth.

As a preferred embodiment, the photochromic coating is formed by adding a photochromic factor to a polyurethane solution.

The utility model discloses an implementation is: when the flexible polaroid is outdoors, the roller 43 is rotated to rotate the rotating shaft 41, the flexible polaroid 5 is released from the storage box 4 by the rotating shaft 41, and can automatically stretch due to gravity to cover the surface of the lens 3, and meanwhile, the lens 3 is changed into a dark color due to a photochromic coating on the surface, and the visible light and the ultraviolet light are effectively intercepted by superposing the two colors; when indoor, the gyro wheel 43 is rotated, makes pivot 41 rotatory, and pivot 41 is at this moment with flexible polaroid 5 income receiver 4 in, lens 3 resumes transparent state simultaneously, makes the person of wearing not influenced at indoor.

The utility model discloses a design point lies in utilizing the transparent lens with photochromic coating and the flexible polaroid that can accomodate to block visible light and ultraviolet ray simultaneously, is fit for outdoor use, and photochromic coating influences lessly to glasses luminousness simultaneously, and flexible polaroid can be accomodate, is fit for indoor place and uses electronic screen.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
