Embodiment:

With reference to Fig. 1, the full frame eyeglass of many spheres gradual change, the surperficial from-inner-to-outer of its circular eyeglass 1 one is provided with center sphere 2 and two to six road luminosity gradual change Spherical Rings 3 successively, more particularly, from center sphere 2, is provided with the Spherical Ring 3 of two to six road luminosity gradual changes outward successively.The centre of sphere of complex trace Spherical Ring 3 and center sphere 2 is on a line perpendicular to eyeglass, and center sphere 2 orthogonal projection radius R is less than 7.5mm, and outermost one Spherical Ring 3 orthogonal projection width B is less than 25mm; Per pass gradual change Spherical Ring 3 luminosity absolute difference is between 10 to 100 degree; Cutting vision correction lens effective coverage 4 comprises center over half sphere 2, more particularly, Shang Yanyu center sphere 2 center of circle orthogonal projection spacing H in the effective district 4 of eyeglass is 3mm-5mm, maximumly comprise Zheng Ge center sphere 2, as dotted portion in figure, it is the eyeglass effective coverage 4 cut out according to framework when joining mirror.Use this circular eyeglass 1, cut-off lens effective coverage 4 can be comparatively flexible, and that is along circular eyeglass 1 center line any rotation, it is just enough that this point is grasped in cutting, can select defect part cutting of having no time.In addition, circular eyeglass 1 another side keeps complete recessed bent face, and in order to the need of processing astigmatism, certainly also do not get rid of non-astigmatic eyes patient, its another side is processed into the structure in plane or male bend face.

With reference to Fig. 2, be front projection figure and the side projection figure of presbyopic lens, in perspective view, dotted line represents the profile of traditional spheric glass; Can find out, the circular eyeglass 1 of center sphere 2 two-sided close to or be exactly parallel, also i.e. zero diopter region or more shallow region; Down become to increase progressively toward side luminosity number, descend edge and side to be luminosity number maximum most, also can think to be exactly the luminosity numerical value of optometry or the luminosity number of higher a grade.When presbyopic is near soon, there is the corrected zone that circular arc is complete, and when seeing far away, namely can pass through the zero diopter district in astrosphere face 2, realize without correct look far away.That is presbyopia is seen far away then more shallow, down or toward side sees and closely just uses darker luminosity number.

As in fact presbyopic lens, namely the rectification luminosity number of far and near eyeglass is general not high yet, and can not exceed+500 degree, if center sphere 2 is zero diopter, per pass absolute difference is 100 degree, is designed to five road gradual change Spherical Rings 3; Or center sphere 2 is 50 degree, all the other 450 degree are evenly distributed to six road gradual change Spherical Rings 3.And few to the rectification number of degrees, both can reduce the absolute difference of per pass Spherical Ring 3, also can reduce the quantity to two of Spherical Ring 3 to three roads.

With reference to Fig. 3, be orthograph and the side projection figure of concave lens, in perspective view, dotted line represents the profile of traditional spheric glass; Can find out, the dihedral angle change of the circular eyeglass 1 of center sphere 2 is maximum, namely corrects the luminosity numerical value of optometry; Down become to successively decrease toward side luminosity number, descend edge and side to be that luminosity number is minimum or for zero diopter district most, also namely look down toward side and see that there is more shallow luminosity number; When such myopia is near soon, can without the need to or to correct less, make eye muscle be in normal relaxation state, myopia is not easily deepened; And when seeing far away, by center sphere, maximum correct amount can be reached, see and far also can see clearly.

Myopia degree is often very high, and as-1200 degree, suppose to control the most shallow area light number of degrees for-800 degree, also namely absolute difference is 400, on mean allocation to six road Spherical Ring 3; If optometry number of degrees person below-500 degree, the Spherical Ring 3 of most outer course can be designed to zero diopter; Lower than-300 degree persons, also can reducing the quantity of Spherical Ring 3, selecting flexibly according to realizing situation.

The center sphere 2 orthogonal projection radius R that this example is mentioned is less than 7.5mm, when ensureing that eyeball is looked squarely, has the region of good few distortion; Outermost one Spherical Ring 3 orthogonal projection width B is less than 25mm, ensures that the lower edge of cutting rear lens effective coverage 4 is in same luminosity district.
