These glasses comprise two lens subassemblies, and each assembly has with the amplifying lens on biconvex surface and a reducing glass with the concave-concave surface. This reducing glass comprises a prism rings, and its image with high-strength light moves and focus on unscathed peripheral part in the retina. The shortcoming of this glasses is, the image of the light that this highly amplifies and strengthens can focus on the peripheral part of amphiblestroid bad or damage. Another shortcoming of this glasses is, these lens do not have the center unimpeded or without prism primitive district, this district is used for adapting to people's good central vision. In addition, in these examples, the image of the light that wherein highly amplifies and strengthen can shine the central vision functional areas in the retina, and generation damages and/or overlaps, and causes occurring blind area or ghost image (double vision).
4,673, No. 263 United States Patent (USP) relates to a kind of glasses, is used for making because spot comes to harm the blurring of image, optic nerve or exists similarly making the people of the problem (wherein making people's central vision decline) of visual impairment strengthen eyesight.

3,628, No. 854 United States Patent (USP) relates to a kind of Fresnel prism, and it is used for for example specific applications of diagnostic test. This Fresnel prism utilizes capillarity to be installed on the conventional correction glasses. In the process that temperature and humidity changes, such capillary mounting means can be subject to the impact of bubble. This Fresnel prism has relatively low light transmittance, and because a lot of concentric prism primitives is pressed in the flexible plastic, is transferred to or projects a plurality of image blurring in the eye. This Fresnel prism also has a lot of other shortcomings, and for example, when the people moved along all directions, projection went out the shadow in groups, and this just causes ghost image, particularly sees the right side when right eye, and left eye is when watching by the nasal side edge of left eyeglass lens lens; When two eye fixations left side, also can produce this situation.
These a plurality of prism primitives have reduced light transmittance, have so just reduced eyesight and have caused the problems such as yctalopia and inconvenience activity. A plurality of concentric prism primitives make same object light by Multi reflection, and (particularly bulb) therefore, forms " 1,000 luminous points ", thereby cause dispersion. Because the impact of the number of a plurality of concentric prism primitives, contrast greatly descends, and the patient is often as watching by a thin graticule mesh. Because the Fresnel prism primitive, the patient must rotate eyes, sees the scene that is expanded in order to see through the prism primitive.
4,779, No. 977 and 4,288, the 18th page of No. 149 United States Patent (USP)s and " The Optician " (publishing in 1972) 4237 phase of the 163rd volume all relate to a kind of basic principle, are about on the glasses that routine that tiny button shape thing or prism primitive with the prism primitive installed or bonded to the patient proofreaies and correct. The exemplary list of references of this tiny prism primitive is disclosed in described reference " The Optician " by Dr.Norman Weiss. The major defect relevant with the use of this button shape thing and/or prism primitive or difficulty are that the prism primitive produces the blurring that is difficult to stand, and be particularly unclear owing to making user see that ghost image gets muddled in the crowd's that everyone moves along all directions situation between the image in front and periphery.
A kind of ophthalmology disease (wherein central vision can greatly weaken because of spot) that is commonly referred to the senile spot blurring of image (N.S.M.D) of macular area change (neovascular) is often because the increase in the spot of eye of blood vessel and break and cause losing one's sight.
A kind ofly be intended to suffer from the people that retina forms pigment, glaucoma, hemianopsia and expand the known glasses improvement project of visual field, center, comprise the lens combination of unbodied telescope-type, wherein at each lens one or more telescopes or lens are installed. These telescopes or lens have dwindled image, so that can see more information in the middle of once in same visual field. The shortcoming of this extended field of view structure is, because each is soon to a plurality of images that approximately only have 1/2 size, so that details does not see Chu. In addition, this telescope outwards stretches a very large distance by glasses, also is very unappealing from upper theory attractive in appearance. These are equipped with telescopical glasses than heavy several times of common glasses so that wear discomfort, often since the moment of torsion that produces by on the ear of user and landing on the nose.
Another kind of known visual field expansion lens comprises use transparent speculum or level crossing in the prior art, and its effect is to be installed on the spectacle frame as an optical splitter, is extended by predetermined angle by nose. The shortcoming of such visual field expansion lens is the image that the user of glasses is seen former and later two separation, may produce significantly smudgy. It is complicated that this speculum or level crossing are installed on the spectacle frame, and causes speculum or level crossing to be installed in the position of exposing, and may be easy to damage and/or lose direction by preposition.
Another scheme for the people's of expansion poor sight visual field comprises special-purpose high dioptric magnifying spectacles, and it can be amplified to object 6 times, enters intraocular so that look thing by the neighboring area simultaneously. The shortcoming of this scheme is the similar protective glasses of these glasses and stretches out about three inches by eye and nose. They must be worn with the lens of soft contact, and heavy and trouble is unappealing on attractive in appearance just.
Therefore, need a kind of figure image intensifying lens, lens can obtain more transmitted light for one of reflection of light, refraction and absorption by reducing at least for it. Also need a kind of lens for glasses, so as to make retina form pigment, suffer from the restriction visual field glaucoma, hemianopsia, can increase the visual field because spottiness makes the blurring of image, myopia, nystagmic people. And the people is had a personal experience of in order to make problem and the shortcoming that existing known trial brings in the visual field of expanding. Also needing cheapness, light, unary bifocal appointment to proofread and correct glasses, is attractive from upper what is said or talked about attractive in appearance. Also need a kind of figure image intensifying lens, can be easy to adopt in various optical systems, the light transmittance that wherein sees through lens improves, and can not produce obvious aberration. Technical scheme of the present invention
The present invention comprises the lens with the prism primitive, and it has a plurality of prism primitives in aggregates on a lens element, and wherein each prism primitive is around one without prism primitive district, by the summit inside, bottom mode outside is orientated. Each prism primitive is contiguous or contact other two prism primitives, thus around described without prism primitive district. The present invention can comprise the project organization parameter of a lot of replacements, comprises taper shape, spheric or aspheric surface shape lens element. In addition, a plurality of prism primitives can be configured on the object space one side or picture side's one side of lens. Therefore, image is by 1: 1 scioptics, do not dwindle, amplification or overlapping. The prism primitive is interpreted as function as the prism unit of a prism, although be this lens part of the whole.
In an example, this lens element with the prism primitive is applied in the lens with the correction of prism primitive, figure image intensifying, eyesight enhancing, a glance lens of ophthalmology, comprise 360 prism primitives, their all summits stop without prism primitive district towards the center of lens. In the first embodiment, one of the object space of lens element one side and picture side's one side form according to totally being sphere basal plane curve.
Eye-use lens is the unary light figure image intensifying lens with the prism primitive, and wherein the interface between each adjacent prisms primitive be can't see concerning naked eyes substantially. These lens can have curvature and the bifocus of appointment as requested, for use in lens being provided for the people who only has eyes to have the quick-eyed functional areas of foveal region of retina, be used for receiving looking thing and having local at least insensitive amphiblestroid neighboring area of visual field, normal center.
In addition, consider that eye-use lens can be reduced to or single eyesight specify correcting lens or bifocus eyesight to specify correcting lens or become non-designated correction be used for strengthening the lens that filter, in order to reduce the ultraviolet ray irradiation. The image of all scioptics refraction all is real image, keeps normally completely size, and does not dwindle or amplify. Specify the lens with the prism primitive of proofreading and correct because the eye-use lens system has, need not make eye locate the visual field of expansion by rotation or shake, thereby not have ghost image. The whole visual field that is image distributes along the optical axis of lens axis and/or patient's eye, thereby makes slur reduce to minimum. Except bifocus or the lines without the window of prism primitive, there is no visible prism primitive lines at lens. Specify the curvature of proofreading and correct to be formed on the object space one side or picture side's one side of lens element. Mould and method for the manufacture of this lens are also disclosed. It is believed that, the glasses with the prism primitive that utilize the appointment among this embodiment to proofread and correct have overcome the central vision decline and substantially because the blind problem that N.S.M.D causes, and other problem for example retina form glaucoma, the hemianopsia of pigment (hole formula eyesight), restriction visual field.
The glasses that lens of the present invention are housed are different from the part on the conventional glasses of the various patients of being attached to, such as Galalean, and Ocutech telescope, unformed lens, amorphous lens, Fresnel prism, tiny prism primitive, level crossing, button shape thing. The visual field that forms by these optical elements is simple eye, perhaps makes the visual field reduced and need the patient to rotate eyeball or sweep their eye, in order to see the visual field of enhancing through tiny prism, button shape thing or level crossing. And when sweeping or rotating their eye so that when seeing through the visual field and strengthening prism, their another eye is also servo-actuated, does not therefore see the edge object, and forms the slur state.
In contrast, utilize lens of the present invention, do not need to make eyeball rotation or sweep, do not have slur. These lens are according to the lens reflection of single element, utilize the test stand of standard or the equivalent of code test sphere to measure best Rx value for each patient. For lens of the present invention, the image of all refractions all is real image, have normally and size completely. Image does not have reduced and amplifies.

For the example that also can be used for 360 wedges with a numerical value that obtains of correcting lens.
Represented in the table 1 for relaxation state the eye in following three kinds of situations, namely normal (need not to proofread and correct), band-1.75D correcting lens, band-1.75D correcting lens, in the situation of 10 millimeters centre bores of described correction prism band and 360 prism primitives, the position of chief ray (image) on retina. Analyze 4 true fields, and provide the spot definition of each visual field. Fig. 1 is light row figure for these three kinds of situations to Fig. 3. Each figure represents the size and dimension for the picture point of 4 visual field points on retina. Left axle is listed the field positions that represents with relative visual field and number of degrees dual mode. The information of the relative position of the each point on the relevant retina is not provided.
In table 2, itemized the eye through regulating. It has listed three kinds of situations for the eye through regulating. The position of the chief ray on retina: namely to normal eye (need not proofread and correct), band+1.75D correcting lens, and band+1.75D correcting lens, this correcting lens is with 10 millimeters centre bores and 360 prism primitives. Divide and rolled over 3 true fields, and provide the spot definition of a visual field. Fig. 4 to 6 is the point range figures for these three kinds of situations.
In all these examples, clearly, with the lens of 360 prism primitives with light towards amphiblestroid off-centring. Although light spot form does not change, the luminous point that produces with 360 prism primitive lens is larger than the spot definition that level and smooth correcting lens produces. Lens with 360 prism primitives also produce a structural formula luminous point. Fig. 7 is illustrated in the luminous point at (0.40) degree field positions place, is comprised of 12 different lines. By trace by each hole ± light (Fig. 8) at x edge, can obtain the track at the lip-deep light beam of wedge. In this case, its angle in the x-y plane is 11.85 ° to string. Therefore, will be distributed in the 12 wedge scopes in 360 wedges from the light of object, be reflected by the structure of light row figure.

Two states to eye that loosen and through regulating is considered 3 kinds of systems: normal; Band ± 1.75D proofreaies and correct; By ± 1.75D proofreaies and correct, and 60 12 dioptric prism primitives arrange around unimpeded hole, one 10 millimeters center.
For each system, similarly exported. Table 1 provides the as follows of each system of analyzing to 6: information is briefly enumerated each system, wherein comprises curvature, thickness and material that each is surperficial. Then, listing horizontal third-order aberration for each surface, then is the total senior aberration for whole system. In output, use following abbreviation:
The SA spherical aberration
The TCO coma
TAS meridian astigmatism
SAS sagitta of arc astigmatism
PTB is cut down the curvature of field hereby
The DST distortion
Output is made of each ray aberration curve for the figure of every kind of system, as shown in Fig. 1 to 6. From the light sector trace of each object location to determining along the x axle of described aperture light beam or y axle, and calculate the position that each light of this object point departs from chief ray. Trunnion axis is normalized aperture coordinate. In the left side of figure, represent the sector of (y) that each is tangential; Represent each light at d-axis and depart from the chief ray coordinate. The right side of figure represents each sagitta of arc (x) sector, and vertical axis provides the x coordinate that light departs from. If have rotational symmetry, only show two minutes of sagitta of arc sector this. For the system with 360 wedges, the sagitta of arc sector that trace is complete. In these examples, the meridian sector is level and smooth, because the y sector is by single wedge trace, and sagitta of arc sector leaf corrugated, because the x sector is by a plurality of wedge traces.
The below considers that 360 wedges are for the impact of the picture position on the retina. Thing is that wherein the z axle is optical axis by the location positioning in the vector at the inclination angle in y-z plane (y angle) and x-z plane (x angle) and the space described. Assess three thread-shaped bodies by trace and vertical curve (the x angle is that 0, y angle changes), horizontal line (the x angle changes, and the y angle is 0) and the corresponding light of one 45 ° of lines (x angle=y angle). In each situation, direction remains unchanged, but the position of figure changes. Because system has symmetry, result's comparison that the result who obtains for horizontal line and vertical curve obtain, except x be identical the y coordinate is put upside down. Therefore only represent the data that obtain according to vertical curve. Table 7 and table 8 have been listed the function of field of view angle of the position of the image eye that loosens changes to(for) the conduct of three objects. In Fig. 7 and 8, express for level and smooth correcting lens with the difference between the picture altitude of the correcting lens of 360 wedges. Flat in the curve is corresponding to the object of the unimpeded borescopic imaging in center of scioptics. Table 9 and 10 and Fig. 9 and 10 identical information of the various situations of the eye through regulating is provided.

This report analysis performance that should " 360 " type structure, this focal power is ± correcting lens of 6D. Situation as at the correcting lens of ± 1.75D, adopt following step in order to obtain this lens:
1 utilizes R[m]=(n CR-39-1)/focal power [D] calculates the radius of curvature of the correcting lens with a flat second surface.
The combination generation that 2 utilize minute other thin equation to calculate adds for the eye total focal power identical with standard eye required focal power. Reckoning is for by the required adjusting of cornea curvature as providing at the Execl articulation statement as shown in table 1 and 2.
3 system inputted Code V and allow cornea curvature and and the asphericity coefficient of cortex of lens change. Angle of visual field optimization to 0 ° and 10 ° makes three grades of spherical aberrations equal 0, and makes the spot definition of weighting minimum.
4 freeze all variablees, and this is for level and smooth correcting lens. For " 360 " type system the surface of user's appointment is added on the second surface of lens.
The output that produces with have ± 1.175D proofreaies and correct lens output identical of focal power, this output provides in stage II report and stage III are reported. Publish in these reports for the description of output and the subprogram that enters on the surface of user's appointment. The situation of the eye of described subprogram is used for the output of design " 360 " this report of surface ± 6D correcting lens level and smooth for wearing and for wear ± 6D comprises that the situation of eye of the correcting lens on 360 surfaces provides. Here there is not repetition for the data of the eye of standard.
When appending to 360 surfaces on the lens, the thickness of wedge so that at the thickness (sag) at rims of the lens place greater than center thickness.
360 surfaces are added to ± the 6D lens on: center thickness 6.4mm
This spot definition and structure are comparable, and produce larger luminous point and depart from, and make luminous point focus on more center near view.
