Description
Technical field
Concave lens is the utility model is related to, it is specifically a kind of comprehensive to slow down other center defocus and cause axial myopia
The eyeglass of intensification.
Background technology
The problem of all kinds of myopia are with 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, cause axis oculi to be forced effort lengthening and go to receive this partial visual information, vicious circle is easily formed to eyeball physiology, caused
Axis oculi, which elongates myopia, further to be deepened, and the product such as in the market existing common sphere, 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 in order to which the utility model that solves the above problems provides one kind
Fall in postretinal eyeglass.
The utility model is achieved through the following technical solutions in order to achieve the above object：
1st, the utility model is a kind of comprehensive eyeglass for slowing down other center defocus and causing axial myopia to deepen, including eyeglass
Body, a diameter of 70-80 millimeters of eyeglass body, eyeglass body include center and fix light area, gradually light changing region and natural transition region,
Center fixes light area and be located at eyeglass body central position, the number of degrees of the gradually light changing region at a diameter of 42 millimeters of eyeglass body and in
The number of degrees difference that the heart fixes 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
It is 70 degree of ﹢ for -50 ~ -100 Curvature varying values, the eyeglass body number of degrees are that -125 ~ -400 Curvature varying values are 80 degree of ﹢, eyeglass body
The number of degrees are that -425 ~ -600 Curvature varying values are 90 degree of ﹢, and eyeglass body number of degrees rate changing value of being write music more than -625 is 95 degree of ﹢.
Further improvement of the utility model is：A diameter of 8 millimeters of light area are fixed at center.
Further improvement of the utility model is：Gradually area of the light changing region between a diameter of 8-45 millimeters of eyeglass body
Domain.
Further improvement of the utility model is：Gradually the astigmatism degree changing value in light changing region is less than ball light Curvature varying
The 70% of value.
The beneficial effects of the utility model are：The number of degrees of eyeglass body in light area are fixed at center in a diameter of 8 millimeters
For fixed value, a diameter of 8 millimeters to 45 millimeters of region is gradually light changing region, and continuous, gradual change gradually is being carried out in light changing region
Become luminosity, reach focus gather effect, lens periphery partial optical focus is fallen on the retina, it is further to slow down myopic degree
Deepen.
The utility model 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 the utility model schematic diagram.
Wherein：Light area is fixed at 1- centers, 2- gradually light changing regions, 3- nature transition regions.
Embodiment
In order to strengthen to understanding of the present utility model, the utility model is made below in conjunction with drawings and examples further
Detailed description, the embodiment be only used for explain the utility model, to the scope of protection of the utility model form limit.
As shown in figure 1, the utility model is a kind of comprehensive eyeglass for slowing down other center defocus and causing axial myopia to deepen,
Including eyeglass body, a diameter of 70-80 millimeters of eyeglass body, eyeglass body include center fix light area 1 gradually light changing region 2 and from
Right transition region 3, center fix light area 1 and are located at eyeglass body central position, the gradual change light at a diameter of 42 millimeters of eyeglass body
The number of degrees difference that the number of degrees in area 2 fix light area 1 with center 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 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, the eyeglass body number of degrees are that -425 ~ -600 Curvature varying values are 90 degree of ﹢, and the eyeglass body number of degrees are less than -625 degree Curvature varyings
It is worth and fixes a diameter of 8 millimeters of light area 1 for 95 degree of ﹢, center, gradually light changing region 2 is between a diameter of 8-45 millimeters of eyeglass body
Region, gradually light changing region（2）Interior astigmatism degree changing value is less than the 70% of Curvature varying value, is ﹢ 60, ﹢ 70, ﹢ in Curvature varying
80th, during ﹢ 90 and ﹢ 95, astigmatism degree changing value must not exceed 42,49,56,64 and 68 degree, fixed at center the number of degrees in light area for-
Number of degrees at 100 degree a diameter of 42 millimeters of position are -30 degree, can make lens periphery optical focus fall as far as possible regarding
On nethike embrane, effectively slow down hypometropia and further deepen, be nature transition region 3 beyond 45 millimeters of diameter, it is only necessary to carry out base
Type connection of this face, reaches attractive in appearance, frivolous effect, does not do specific optical requirement, and gradually light changing region 2 is divided for several transition regions, several
Transition region is from the transition region of most inner side to the radius of outermost transition region into arithmetic progression.
The utility model is simple in construction, reasonable in design, and optical focus can be made to fall on the retina, effectively slows down near-sighted journey
Degree is deepened.
