Description

One-line eye protection degree control glasses

Technical Field

The utility model belongs to the myopia glasses field, more specifically the utility model relates to a ray of eyeshield accuse degree mirror that says so.

Background

The myopia glasses are glasses for correcting vision and making people clearly see objects far away, and aim at keeping certain accommodation capacity of ciliary muscle of eyeball.

The myopia glasses have certain prevention effect on complications caused by high myopia, such as retinal detachment, vitreous opacity, cataract, glaucoma, nystagmus and the like. The spectacles for myopia are concave lenses. The image formed by a concave lens, which is mainly used to correct myopic eyes, is always smaller than the upright virtual image of an object. The degree of the glasses is as follows: the refractive power of an ophthalmic lens is generally expressed in degrees. One diopter, equal to 100 degrees spoken by an average person or a spectacle shop, i.e., D1.00 in non-chinese countries. The more serious the vision problem, the deeper the required lens power and the higher the lens thickness.

In the prior art, a degree is directly on a myopia glasses, but as everyone pays for the adjusting power when seeing, the closer the reading distance is, the larger the paid adjusting power is. The normal eyesight person (emmetropia) pays 2D adjustment force when seeing things at a distance of 50cm, and the adjustment force is increased to 10D when seeing a distance of 10 cm. Particularly, for some people who need to see near for a long time, such as students, office workers and the like, the glasses with single degree in the prior art cannot meet the requirements, and glasses with multiple degrees are urgently needed to meet the use requirements of different environments.

Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.

As shown in fig. 2, the utility model discloses a lens of technical scheme includes light zone 13 and lower light zone 12 for a clamping piece structure sketch map of a ray of eyeshield accuse degree mirror. The dividing line 18 between the upper and lower light areas 13, 12 is located 1mm below the eyelids when worn by the wearer. The boundary 18 between the upper light area 13 and the lower light area 12 is a horizontal straight line.

Based on upper segment technical scheme, set up the light zone of two kinds of degrees on a lens, improve the adaptability of glasses for the person of wearing for a long time a pair glasses also can satisfy the different demands of seeing closely and seeing far away simultaneously, and wears this technical scheme's accuse degree mirror for a long time, increase that can effectual control degree.

Each person needs to pay out the adjustment power when seeing near, and the closer the reading distance, the larger the adjustment power that pays out. The formula for calculating the adjusting force is as follows: the accommodation force F is 1/distance D from the fixation point of the eye to the eyeball (i.e., D is 1/F), which is measured in meters. According to the formula, the adjustment force needed by the eye distance of different wearers can be calculated.

The normal eyesight person (i.e. emmetropia) pays 2D for watching things at a distance of 50cm, and when watching at a distance of 10cm, the power of the adjustment increases to 10D. The ADD value is obtained by subtracting the near-viewing number from the far-viewing number, i.e., ADD is the near-viewing number-the far-viewing number.

And calculating the ADD value according to the ADD formula of the near reading degree-the far reading degree, wherein if the upper light region degree is-300 and the lower light region degree is-100, the ADD value is-100- (-300) or 200, and the ADD value is + 200. For another example: the upper light area has a power of-150 and the lower light area has a power of +125, and the ADD value is +125- (-150) ═ 275, that is, the ADD value is + 275.

The standard special control glasses are mainly used for prevention and control, and the ADD value is usually +200 to +300, so that the prevention and control failure caused by the fact that a wearer does not want to use the glasses due to the fuzzy lower light area is avoided.

As shown in fig. 1 and 2, the utility model discloses an online eyeshield degree of control mirror among the technical scheme, including mirror holder 7 and clamping piece 10, clamping piece 10 includes lens and lens frame, and the lens frame includes two lens frames 11 and connects the crossbeam 14 of two lens frames 11, is provided with clamping part 15 on two lens frames 11, and clamping piece 10 passes through clamping part 15 centre gripping on mirror holder 7, and clamping piece 10 can be the axle upset by clamping part 15.

As shown in fig. 4, the clip 10 is flipped down onto the frame 7, i.e. the glasses are worn normally. When the wearer does not need to wear the glasses temporarily, the clamping piece is turned upwards, as shown in the state of fig. 5, the spectacle frame is a hole frame, and no lens is shielded in the sight range of the wearer.

The design of the structure of clamping piece among this technical scheme makes clamping piece 10 and 7 centre gripping positions of mirror holder disperse evenly on the one hand, and it is big to appear 7 local atress of mirror holder, is difficult to the problem of keep balance in wearing, and on the other hand, this clamping position of clamping piece 10 simple structure can upwards overturn by arbitrary angle, better keep the balance of mirror holder 7 after the upset.

As shown in fig. 1, the technical solution of the present invention is that the mirror holder 7 includes two mirror frames 1, the top of the two mirror frames 1 is provided with a linear frame rod 3, and a nose bridge rod 2 is connected between the two mirror frames 1. Set up nose bridge pole 2 and crossbeam 14 on mirror holder 7 and the clamping piece 10 respectively, nose bridge pole 2 and crossbeam 14 can not interfere each other, and realize respectively the wholeness to mirror holder 7 and clamping piece 10, reduce the weight of this degree of control mirror, increase the travelling comfort when the person of wearing.

As shown in fig. 1, the frame rod 3 of the present invention comprises a frame rod body, and the frame rod body is coated with a magnetic sleeve 4 and a rubber sleeve 5 at an interval outside the frame rod body.

As shown in fig. 2 and 3, in the technical solution of the present invention, the clamping portion 15 includes a clamping sleeve that is respectively disposed on the two lens frames 11 and is linear, the clamping sleeve is disposed near the lens holder 7 side and is provided with a clamping groove 17, and a magnetic groove 16 is disposed in the clamping groove 17. The clamping groove 17 is adapted to the frame rod 3, the frame rod 3 is arranged in the clamping groove 17, and the magnetic sleeve 4 is attracted to the magnetic groove 16.

Based on above-mentioned technical scheme, magnetism cover 4 and magnetic slot 16 attract mutually, and rubber sleeve 5 plays inflation and sealing action for be cylindric frame pole 3 can be in the inside indefinite and passive rotation of centre gripping groove 17 that is the semi-cylindrical, and can realize the auto-lock. So that the wearer can turn the clip 10 to any angle and fix it when not needed for wearing for a while. This operation, the effectual frequent operation of accomodating glasses and taking out glasses or wearing glasses of operator has been avoided.

As shown in fig. 1 and 2, the bottoms of the two mirror frames 1 are respectively provided with a first magnetic stripe 6. The bottom of the two lens frames 11 is provided with a second magnetic strip 17, and the second magnetic strip 17 and the first magnetic strip 1 are attracted. The second magnetic strip 17 attracts the first magnetic strip 1, thereby further increasing the reliability of the direct mounting connection between the clip 10 and the frame 7.

The technical solution of the present invention is to provide an improved method for manufacturing a semiconductor device, which is characterized in that the method is not limited by the above-mentioned method, and the method is not substantially improved by the method and the device, or the method and the device are directly applied to other occasions without improvement, all within the protection scope of the present invention.
