Description
Technical field
Lens technology field is the utility model is related to, specifically a kind of antifatigue inner progressive multiple-focus eyeglass.
Background technology
It is the very formidable key issue of ophthalmic progressive additional lens to deform astigmatism, although testing with proper gradation zone
Wearer's clearly eyesight can be given, but a certain degree of imaging distortion will be produced in gradual change groove both sides, its deformation extent and change
Shape direction depends on the depth of the different and additional number of degrees of lens design, and when eyes, to leave gradual change groove center region more remote, as matter
Deformation is more obvious.Because near reading range is spherical designs, so near reading range is wider, the astigmatism that its periphery induces is bigger,
On the contrary, the problem of near reading range domain is narrower, and its induction property deforms astigmatism is just smaller, induction property peripheral distortion astigmatism is equally with additional degree
Several change and change, the near-sighted near addition number of degrees are bigger, and peripheral distortion problem is more obvious, so how effectively to reduce periphery phase
The design of poor deformed region is particularly important.
The content of the invention
In order to solve the above problems, the utility model provide it is a kind of with multifocal, comfortable wearing it is antifatigue in gradually
Enter multifocal lens.
The utility model is achieved through the following technical solutions in order to achieve the above object：
The utility model is a kind of antifatigue inner progressive multiple-focus eyeglass, including eyeglass body, and eyeglass body includes regarding remote
Area, intervening fade transition region, near reading range, peripheral astigmatism area, far field is regarded as inner surface sphere curved surface, intervening fade transition region and regard
Near region is inner surface aspheric free form surface, and the passage length of intervening fade transition region is 12-16 millimeters, and peripheral astigmatism area includes
One-level bias spread area and two level bias spread area, one-level bias spread area is close to regarding far field, intervening fade transition region and regarding near
The curved edge in area, two level bias spread area is from one-level bias spread area to eyeglass body edges.
Further improvement of the utility model is：Long sight aberrationless area is regarding the 3/4 of far field.
Further improvement of the utility model is：Near-sighted aberrationless area is the 1/2 of near reading range.
Further improvement of the utility model is：To optimize visual spread area, two level is eccentric to be dissipated for one-level bias spread area
Light area is for the passage of increase intervening fade transition region and regarding the non-visible deformation spread area of far field area.
Further improvement of the utility model is：Near reading range photometric range is 0.75D-3.50D.
The beneficial effects of the utility model are：By changing the function in peripheral astigmatism area, effectively improve intermediate transition zone and
Depending on the effective area in far field, near reading range, so as to substantially improve the practicality of inner progressive multiple-focus eyeglass, have and slow down wearer's eye
The effect of eyeball fatigue.
The utility model is simple in construction, reasonable in design, depending on far field and near reading range middle transition naturally, wearer easily fits
Should, there is the effect for slowing down eye fatigue.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein：1- regards far field, and 2- intervening fade transition regions, 3- near reading ranges, 4- one-level bias spread area, 5- two levels are eccentric to be dissipated
Light area.
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.
