Description

A kind of glasses of adjustable astigmatism degree

Technical field

The utility model is related to spectacles industry, especially a kind of adjustable astigmatism that astigmatism degree can be adjusted Several glasses.

Background technology

Myopia is generally existing in current society, along with myopia be astigmatism the problem of.Chinese myopia population In, astigmatism reaches 35% to 40% in 75 degree or more of people, but many people ignore the correction to astigmatism.Astigmatism is to seeing remote see closely All have an impact, the general uncorrected visual acuity of slight astigmatism it is impacted less, ophthalmic uncomfortable may be susceptible to, as headache, asthenopia, Eye-blurred etc..But serious astigmatism, it can not see and distort depending on object, see that object also has ghost image.This is because dissipating Just corneal thickness is irregular or curvature is irregular, and each meridianal flexion rate of cornea is inconsistent, causes light that cannot accurately gather Coke forms clearly image on the retina.If child's astigmatism is corrected not in time, visual development is influenced whether, cause amblyopia, Can also forming a habit property narrow eye, rub one's eyes, torticollis etc., and it is regular rub one's eyes and narrow one's eyes, be likely to that cornea is caused to occur This situation.It wears astigmatic glasses to be corrected, is the selection of people, but the astigmatism degree of existing astigmatic glasses can not be adjusted, Cannot meet the needs of eyesight variation, and if astigmatism test is inaccurate when getting the right lensses for one's eyeglasses that wearer will be made to aggravate astigmatism journey Degree, does not have eyesight the effect of correction.

Utility model content

For existing deficiency, the utility model, which provides, a kind of can be regarded the glasses that astigmatism degree is adjusted to coordinate The demand of power variation, better correction is played to eyesight.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of glasses of adjustable astigmatism degree, including primary frame, temple, the temple is hinged in primary frame, described Primary frame is embedded with astigmatic lens and astigmatic lens can be rotated relative to primary frame；The astigmatic lens are one circumferentially arranged with more The gradual change astigmatic lens of the different astigmatism degree block of kind.

Preferably, described primary frame the right and left is embedded with front and back two astigmatic lens arranged side by side, each astigmatic lens It can all be rotated relative to primary frame.

Preferably, each astigmatic lens edge is there are one auxiliary spectacles frame, each auxiliary spectacles frame is embedded in primary frame It is interior and relative to primary frame rotate.

Preferably, the outer rim of each auxiliary spectacles frame is equipped with the positioning protrusion with primary frame cooperation positioning.

Preferably, the auxiliary spectacles frame is metal frame.

Preferably, being carved with the scale of mark astigmatism degree on the astigmatic lens.

Preferably, the astigmatism degree block is provided with astigmatismus regularis and the astigmatism degree block of negative astigmatism.

Preferably, the edge of the astigmatic lens is equipped with the adjusting protrusion for adjusting eyeglass rotation.

Preferably, the primary frame is frame made of TR materials.

The beneficial effects of the utility model are：Astigmatic lens are rotated relative to primary frame in the utility model, as needed Astigmatism degree can carry out the adjusting of the number of degrees and axis of astigmatism, meet the needs of different, the astigmatism situation of eyesight carried out more Good correction.

Specific implementation mode

Purpose, technical scheme and advantage in order to illustrate the embodiments of the present invention more clearly are clearer, below in conjunction with The utility model is described in further detail for accompanying drawings and embodiments, carries out clear, complete description, it is clear that described embodiment It is the section Example of the utility model, rather than whole embodiments.Based on the embodiment of the present invention, ordinary skill people The every other embodiment that member is obtained under the premise of not making the creative labor, belongs to the protection model of the utility model It encloses.

Shown in the utility model embodiment is as shown in Figure 1 to Figure 4, a kind of glasses of adjustable astigmatism degree, including primary frame 1, temple 2, the temple 2 are hinged in primary frame 1, and the primary frame 1 is embedded with astigmatic lens 3 and astigmatic lens 3 can be opposite Primary frame 1 rotates, and can be rotated clockwise or counterclockwise according to different situations；The astigmatic lens 3 are one and circumferentially set There are many gradual change astigmatic lens of different astigmatism degree blocks 30, the number of degrees that thus can be as needed carry out astigmatism degree And the adjusting of axis of astigmatism.

It is further to improve, as shown in Figure 1, Figure 3 and Figure 4 shown in, due to the limited area of single eyeglass, on single eyeglass The number that astigmatism degree block is arranged will be limited, then adjustable number of degrees just have limitation, therefore the primary frame 1 is left Right both sides are embedded with front and back two astigmatic lens 3 arranged side by side, and each astigmatic lens 3 can rotate relative to primary frame 1, pass through in this way The superposition of the number of degrees will expand the adjusting of astigmatism degree on front and back astigmatic lens 3, can be rotated simultaneously after adjusting the number of degrees Front and back eyeglass is adjusted axis of astigmatism and can be worn to eyesight correct.

It is further to improve, as shown in Figure 1 to Figure 4 shown in, in order to protect eyeglass in rotation, be unlikely to cause mirror Piece rotation abrasion or damage, then there are one auxiliary spectacles frames 4, each auxiliary spectacles frame 4 to be embedded in master for edge for each astigmatic lens 3 It is rotated in frame 1 and relative to primary frame 1.

Further to improve, as shown in Figures 1 and 2, the outer rim of each auxiliary spectacles frame 4 is equipped with to be coordinated with primary frame 1 The positioning protrusion 40 of positioning, is just fixed after being adjusted in place the number of degrees in this way, will not be slipped and be caused in use The number of degrees are inaccurate, influence the correction to eyes.The auxiliary spectacles frame 4 is metal frame, and metal frame is unlikely to deform, durable.It is described Primary frame 1 is frame made of TR materials, and TR materials have elasticity, just facilitate metal under the resilient engagement of TR materials in this way The rotation and positioning of frame.

It is further to improve, as shown in Figures 1 and 2, the scale of mark astigmatism degree is carved on the astigmatic lens 3 31 so that it is convenient to adjustings of the people to the number of degrees, it is known that the required position for adjusting the number of degrees, it is easy to use.

Further to improve, as shown in Figures 1 and 2, the astigmatism degree block 30 is provided with astigmatismus regularis and negative astigmatism Astigmatism degree block, then can be by astigmatic lens 3 to just if the astigmatism astigmatismus regularis of people according to the difference of astigmatism situation The astigmatism degree block of astigmatism is adjusted, if negative astigmatism is then adjusted to the astigmatism degree block of negative astigmatism, meets the needs of different.

It is further to improve, as shown in Figure 1 to Figure 4 shown in, for convenience to the adjusting of eyeglass rotation, the astigmatic lens 3 Edge be equipped with adjust eyeglass rotation adjusting protrusion 32.

It should be understood that for those of ordinary skills, it can be modified or changed according to the above description, And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
