Description
Technical field
It is specifically a kind of comprehensive to slow down other center defocus and cause axial myopia to deepen the present invention relates to concave lens
Eyeglass.
Background technology
The problem of all kinds of myopia use correcting lens generally existing peripheral optical focus and inconsistent central optical focus at present,
For the teenager in growing, because the peripheral part optical focus of concave lens fall in retina backward
Position, causes axis oculi to be forced effort lengthening and goes to receive this partial visual information, easily form vicious circle to eyeball physiology, cause
Axis oculi, which elongates myopia, further to be deepened, and the product such as the existing common sphere of in the market, aspherical, antifatigue, progressive additional is all
Gather effect without obvious comprehensive focus.
The content of the invention
Lens periphery partial optical focus can be greatly decreased the invention provides one kind in order to solve the above problems to fall
Postretinal eyeglass.
The present invention is achieved through the following technical solutions in order to achieve the above object：
1st, the present invention is a kind of comprehensive to slow down the eyeglass that other center defocus causes axial myopia to deepen, including eyeglass body, mirror
A diameter of 70-80 millimeters of piece body, eyeglass body includes center and fixes light area, gradually light changing region and natural transition region, and center is solid
Ding Guang areas are located at eyeglass body central position, and the number of degrees of the gradually light changing region at a diameter of 42 millimeters of eyeglass body are fixed with center
The number of degrees difference in light area is Curvature varying value, and eyeglass body is that zero diopter Curvature varying value is 60 degree of ﹢, the eyeglass body number of degrees are -50 ~ -
100 Curvature varying values are 70 degree of ﹢, and the eyeglass body number of degrees be that -125 ~ -400 Curvature varying values are 80 degree of ﹢, the eyeglass body number of degrees are -
425 ~ -600 Curvature varying values are 90 degree of ﹢, and the eyeglass body number of degrees write music rate changing value more than -625 for 95 degree of ﹢.
Further improvement of the present invention is：A diameter of 8 millimeters of light area are fixed at center.
Further improvement of the present invention is：Gradually light changing region be eyeglass body it is a diameter of 8-45 millimeters between region.
Further improvement of the present invention is：Gradually the astigmatism degree changing value in light changing region is less than ball light Curvature varying value
70%。
The beneficial effects of the invention are as follows：The number of degrees that eyeglass body in light area is fixed at center in a diameter of 8 millimeters are solid
Definite value, a diameter of 8 millimeters to 45 millimeters of region is gradually light changing region, and continuous, gradual change light is carried out in gradually light changing region
Degree, reaches that focus gathers effect, lens periphery partial optical focus is fallen on the retina, slow down myopic degree and further add
It is deep.
The present invention is simple in construction, reasonable in design, and lens periphery optical focus can be made to fall as far as possible on the retina, effectively
Slow down myopic degree intensification.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Wherein：Light area is fixed at 1- centers, 2- gradually light changing region, 3- nature transition regions.
Embodiment
In order to strengthen the understanding of the present invention, present invention work is further retouched in detail below in conjunction with drawings and examples
State, the embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limited.
As shown in figure 1, the present invention be it is a kind of it is comprehensive slow down other center defocus cause axial myopia deepen eyeglass, including
Eyeglass body, a diameter of 70-80 millimeters of eyeglass body, eyeglass body includes center and fixes light area 1 gradually light changing region 2 and natural mistake
Cross area 3, center fixes light area 1 and is located at eyeglass body central position, the gradually light changing region 2 at a diameter of 42 millimeters of eyeglass body
The number of degrees difference that the number of degrees fix light area 1 with center is Curvature varying value, and eyeglass body is that zero diopter Curvature varying value is 60 degree of ﹢, eyeglass
The body number of degrees are that -50 ~ -100 Curvature varying values are 70 degree of ﹢, and the eyeglass body number of degrees are that -125 ~ -400 Curvature varying values are 80 degree of ﹢,
The eyeglass body number of degrees are that -425 ~ -600 Curvature varying values are 90 degree of ﹢, and the eyeglass body number of degrees write music rate changing value less than -625 for ﹢
95 degree, a diameter of 8 millimeters of light area 1 are fixed at center, gradually region of the light changing region 2 for eyeglass body between a diameter of 8-45 millimeters,
Gradually light changing region（2）Interior astigmatism degree changing value is less than the 70% of Curvature varying value, is ﹢ 60, ﹢ 70, ﹢ 80, ﹢ 90 in Curvature varying
During with ﹢ 95, astigmatism degree changing value must not exceed 42,49,56,64 and 68 degree, it is -100 degree that the number of degrees in light area are fixed at center
When the number of degrees a diameter of 42 millimeters of position be -30 degree, the optical focus of lens periphery can be made to fall as far as possible in retina
On, effectively slow down hypometropia and further deepen, be nature transition region 3 beyond 45 millimeters of diameter, it is only necessary to carry out basic side
Type is connected, and reaches attractive in appearance, frivolous effect, specific optical requirement is not done, and gradually 2 points of light changing region is several transition regions, several gradual changes
Area is from the transition region of most inner side to the radius of outermost transition region into arithmetic progression.
The present invention is simple in construction, reasonable in design, and optical focus can be made to fall on the retina, effectively slow down myopic degree and add
It is deep.
