Description
Technical field
The present invention relates to eyeglass field more particularly to a kind of improvement type ring focus lens.
Background technique
Present electronic equipment is originally more universal and the increase of learning pressure, teenager see daily electronic curtain and reading when
Between it is more and more, high-intensitive daily makes teen-age eye pressure very big with eye, is easy fatigue, can if things go on like this bring one
The view problem of series.
In response to this, it is slow to help teenager to loosen eyes to have devised various visual training equipment by people
Solution asthenopia.The method of mainstream is that focus-variable lens are applied to wearable device at present, when user wears this equipment
When, crystalline lens in the eyes of wearer is made by the lens area that mobile eyeglass makes eyes correspond to different diopters
Adjusting achievees the purpose that loosen and take exercise.
Current focus-variable lens are then to be carried out cutting using circular ring focus lens to ring focus lens and formed for eyesight
Trained eyeglass, the upper of current circular rings focus lens have multiple annulus, these annulus are in the ring with annular eyeglass concentric
Shape.The ratio for accounting for entire eyeglass using the effective coverage that such eyeglass is cut into visual training eyeglass is smaller, can be to eyeglass material
Material causes very big waste.
In addition, in practical applications, all lens are all imagings that cannot be absolutely accurate according to optical theory, deviate master
Optical axis is remoter, that is, edge imaging is poorer, this is in optics aberration.Because this person is when seeing object through eyeglass, lead to
The primary optical axis for crossing eyeglass sees that object is that effect is best, clearest, if seeing that object, image objects can generate by the edge of eyeglass
Deformation makes one to generate spinning sensation.
Summary of the invention
The technical problem to be solved by the present invention is in order to solve using traditional ring focus lens cutting visual training eyeglass
The visual training eyeglass that the ratio that effective coverage accounts for entire ring focus lens is smaller, wastes the problem of material and is cut into was using

In, unless otherwise indicated, the meaning of " plurality " is two or more.
As shown in Fig. 2 ~ 3, the present invention provides a kind of improvement type ring focus lens, comprising:
Improving type ring focus lens 1 includes central area 2 and from the successively continuously distributed multiple tracks annulus 3 outward of central area 2.Ring
Two surfaces with 3 are a part of complete sphere, and per pass annulus 3 has a diopter.Two surfaces of central area 2
It is a part of complete sphere.
The primary optical axis of annulus 3 and the primary optical axis of central area 2 are coplanar, the primary optical axis of annulus 3 and the key light of central area 2
Axis is parallel to each other.
The primary optical axis and improvement type ring focus lens 1 of central area 2 intersect at central point.Central point is close to improvement type ring coke mirror
The edge of piece 1 is arranged.
Improve the effective coverage 4 on type ring focus lens 1 with cutting visual training eyeglass.The primary optical axis of annulus 3 and improvement
The intersection point of type ring focus lens 1 is respectively positioned in effective coverage 4, and central point also is located in effective coverage 4.
Visual training eyeglass is cut using ring focus lens, when in use, before visual training eyeglass is placed in human eye
Side makes human eye correspond to the different annulus 3 of visual training glasses on piece, instructs to penetrate eyesight by mobile visual training eyeglass
Practice eyeglass and see objects in front clearly, human eye meeting active accommodation is lenticular to be shunk and loosen, and is reached and is loosened human eye, takes exercise lenticular
Purpose.
As shown in Figure 1, the central area 2 of traditional ring focus lens is located at the center of circular eyeglass, its annulus 3 is in
The concentric annular with circular eyeglass.Since the annulus 3 of the two sides in the center of circle of traditional ring focus lens is symmetrical, variation range is consistent,
Therefore using the most of center of circle that can be only positioned at circular eyeglass in effective coverage 4 of traditional ring focus lens cutting visual training eyeglass
Side.It causes diopter variation range in effective coverage 4 small in this way, and not high to the utilization rate of entire ring focus lens, causes
The waste of material.
This improvement type ring focus lens and traditional ring focus lens, this improvement type ring are made using an equal amount of eyeglass
The area of the effective coverage 4 of cutting visual training eyeglass is greater than the area of the effective coverage 4 of traditional ring focus lens in focus lens,
The area of effective coverage 4 becomes larger, then the road number of the annulus 3 of the effective coverage 4 of cutting visual training eyeglass also becomes more, cuts
The diopter variation range for cutting the effective coverage 4 of visual training eyeglass also becomes larger.Therefore, this improvement type ring focus lens piece is more
Supernumerary segment about material and performance is more preferable.
In addition, in practical applications, all lens are all imagings that cannot be absolutely accurate according to optical theory, deviate master
Optical axis is remoter, that is, edge imaging is poorer, this is in optics aberration.Because this person is when seeing object through eyeglass, lead to
The primary optical axis for crossing eyeglass sees that object is that effect is best, clearest, if seeing that object, image objects can generate by the edge of eyeglass
Deformation makes one to generate spinning sensation.And visual training eyeglass often cooperates wearable device (such as VR glasses) to use, it is wearable
Equipment can drive visual training eyeglass to move linearly, and in this process, the position of human eye is constant.If instructed in eyesight
During practicing eyeglass movement, the primary optical axis of the annulus 3 in front of user's sight cannot be right through human eye, then using
Person will generate uncomfortable feeling when seeing object through the annulus 3.And the improvement type ring focus lens in the present embodiment
Annulus 3 primary optical axis and central area 2 primary optical axis it is coplanar, the primary optical axis of annulus 3 and the primary optical axis of central area 2 are mutual
It is parallel.With this visual training eyeglass that is cut into of improvement type ring focus lens when in use, visual training eyeglass along
Linear movement enables to the primary optical axis positioned at different annulus 3 successively to pass through human eye, so that user's view object is clear, training
Effect is good.
In the particular embodiment, effective coverage 4 is in elongated, and length direction of the multiple tracks annulus 3 along effective coverage 4 successively divides
Cloth.The primary optical axis of annulus 3 is sequentially distributed with the intersection point for improving type ring focus lens 1 along the length direction of effective coverage 4.It is using
In it is general all by visual training eyeglass cut growth shape, when in use, visual training eyeglass is drive before being placed in human eye along it
Length direction is mobile, and the primary optical axis of different annulus 3 is enabled to successively to pass through human eye.
According to other embodiment, the diopter closer to the annulus 3 of central area 2 is bigger, the diopter of central area 2
Greater than the diopter of innermost annulus 3.
According to other embodiment, the diopter closer to the annulus 3 of central area 2 is smaller, the diopter of central area 2
Less than the diopter of innermost annulus 3.
According to other embodiment, the absolute value of the difference of the diopter between every two adjacent annulus 3 is equal.Center
The absolute value of the difference of the diopter of the diopter in domain 2 and innermost annulus 3 is equal to the dioptric between every two adjacent annulus 3
The absolute value of the difference of degree.The absolute value of the difference of diopter between every two adjacent annulus 3 is 0.2D.
According to other embodiment, the diopter of central area 2 is equal to 0D, and the diopter of annulus 3 is less than 0D(, that is, diopter
It is negative).This eyeglass is suitable for myopia population.
