Double-lens glasses

Technical Field

The utility model belongs to the technical field of glasses, concretely relates to double-lens glasses.

Background

In recent years, with the increase of the study pressure of students and the increase of the working time of workers facing computers, myopia patients are more and more caused by long-time use of eyes. Meanwhile, with the improvement of living standard, more and more people begin to pay attention to the protection of eyes, for example, the sunglasses can be worn when the sunlight is strong, so that the damage of ultraviolet rays to the eyes is reduced. In some special occasions, such as the requirement of drivers for anti-glare functions at night and the requirement of anerythrochloropsia patients for identifying traffic lights, people often need sunglasses with different functions. When the myopia patient wears the frame glasses, the sunglasses are inconvenient to wear. The existing glasses are provided with sunglasses and myopia glasses, a clamping piece is usually added on the basis of the original myopia glasses or a frame provided with the sunglasses is connected to an original myopia glasses frame, for example, in the patent document with the application number of CN201410691380.8, the sunglasses are arranged on the myopia glasses in a plugging mode, the mounted sunglasses and the myopia glasses are too heavy to press the bridge of the nose, and the sunglasses are plugged on the frame of the myopia glasses, so that the relative position between the sunglasses and the myopia glasses can be swayed or deviated, and the wearer can be dizzy.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a pair of lens glasses, the utility model aims to solve the technical problem that: how to make glasses have the function of adjusting eyesight and resisting outdoor sunshine, promote the travelling comfort of the person of wearing simultaneously.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a pair of lens glasses, including picture frame and optical lens, set up the lens mounting hole of placing optical lens on the picture frame, a serial communication port, encircle along its circumference on the inner wall of lens mounting hole and set up the circular arc recess that prevents optical lens and deviate from backward, the cell wall of circular arc recess is the cambered surface, optical lens leans on with the cell wall counterbalance of circular arc recess, encircle along its circumference on the inner wall of lens mounting hole and set up the joint groove, the joint groove is located the place ahead of circular arc recess, joint has protective lens in the joint groove, protective lens leans on with the optical lens counterbalance.

The optical lens is placed in the lens mounting hole, the optical lens is attached to the arc groove, the groove wall of the arc groove is a cambered surface, the groove wall prevents the protective lens from falling off backwards, a clamping groove is formed in the front of the arc groove, the front and the back of the spectacle frame are determined according to the front and the back of a person wearing spectacles, the clamping groove is clamped with the protective lens, the protective lens is abutted against the optical lens, and the optical lens is abutted against the groove wall of the arc groove, so that the optical lens is fixed on the spectacle frame, the optical lens and the protective lens are directly and fixedly connected with the spectacle frame, the relative position between the optical lens and the protective lens is stable, when the spectacle frame is worn, the optical lens and the protective lens cannot generate mutual displacement, and the situation that the wearer is dizzy due to the relative displacement of the optical lens; because optical lens supports through leaning on with circular arc recess and protective glass piece, need not set up the joint structure who is used for fixed optical lens piece alone on the picture frame, reduce the interval between protective glass piece and the optical lens piece, make the picture frame keep less thickness, the structure is more compact, and this glasses can satisfy near-sighted and outdoor sun of keeping out, do not produce unnecessary pressure to the bridge of the nose again.

In foretell double-lens glasses, the area of protection lens is greater than optical lens, is equipped with on the picture frame and supports to lean on the face, supports to lean on the face to be located between circular arc recess and the joint groove, supports to lean on the face to link to each other with the cell wall in circular arc recess and joint groove respectively, the back mirror surface of protection lens with support to lean on by the face. The area of the protective lens is larger than that of the optical lens, so that the protective performance of the protective lens is reliable, and the rear lens surface of the protective lens is supported against the abutting surface to avoid the protective lens from directly extruding the optical lens to generate friction when being mounted, so that the definition of the lens is influenced.

In the above-mentioned double-lens glasses, the rear lens surface of the protection lens is a forward concave arc surface, the rear lens surface of the protection lens abuts against the edge of the optical lens, and a gap is formed between the rear lens surface of the protection lens and the front lens surface of the optical lens. The rear mirror surface through the protection lens leans on the cooperation circular arc recess to fix optical lens in the picture frame with optical lens's border counterbalance, and the contact between the two can be reduced in the clearance between the front mirror surface of optical lens and the rear mirror surface of protection lens, and when protection lens received impact or striking, certain cushioning effect can be played in the clearance between the two, avoids optical lens to receive the damage.

In the above-mentioned double-lens glasses, the outer peripheral wall of the optical lens is provided with a profiling surface abutted against the arc groove. The profiling surface arranged on the optical lens increases the reliability of matching with the arc groove.

In the double-lens glasses, the groove wall of the arc groove is also provided with a limiting groove, and the profiling surface of the optical lens is provided with a limiting convex rib matched with the limiting groove. The arrangement of the limiting convex ribs and the limiting grooves enables the cooperation between the optical lenses and the glasses frame to be firmer, and even if the protective lenses accidentally drop, the optical lenses cannot lose the limiting function and drop.

In the above-mentioned double-lens glasses, an arc transition chamfer is provided between the groove wall of the arc groove and the limit groove. When the optical lens is installed, the arc transition chamfer angle between the limit groove and the arc groove enables the limit convex rib to enter the limit groove more easily, and the arc transition chamfer angle has a guiding effect.

Compared with the prior art, the double-lens glasses have the following advantages:

1. the optical lenses are fixed in the glasses frame through the protection lenses matched with the arc grooves, so that the structure of the glasses is more compact, and the compression on the bridge of the nose is reduced.

2. The edge of the protective lens abuts against the edge of the optical lens, and the gap formed between the protective lens and the optical lens can effectively avoid unnecessary friction between the protective lens and the optical lens.

3. Through spacing protruding muscle on the spacing recess cooperation optical lens on the picture frame, even the protective glass piece accident drops, optical lens still can be fixed on the picture frame, the basic visual acuity of guarantee user is adjusted.
