Specific embodiment
It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer
Each embodiment of type is explained in detail.However, it will be understood by those skilled in the art that each in the utility model
In embodiment, many technical details are proposed in order to make reader more fully understand the utility model.But even if without this
A little technical details and various changes and modifications based on the following respective embodiments, also may be implemented each claim of the utility model
Technical solution claimed.
Aberration: aberration divides low order aberration and higher order aberratons.Low order aberration is including near-sighted, long sight, astigmatism, and higher order aberratons include
The various aberrations except these low order aberrations are removed, such as irregular aberration is mostly made of various higher order aberratons.Such as angle
Patient after film transplanting has 500 degree of myopia in a quadrant, another quadrant may because anterior corneal surface is not smooth enough
Have 200 degree of myopia, just as the hills of a surface undulation injustice, therefore conventional eyeglass can not correct it is such ametropia.
Described in background technique as above, in combination with shown in Fig. 1, Fig. 2, wherein Fig. 1 be showing of correcting defects of vision of wearing near-sighted glasses
It is intended to, Fig. 2 is the schematic diagram of smooth surface near-sighted glasses；It can be seen that common near-sighted glasses, presbyopic glasses etc. can no doubt be corrected closely
Depending on etc. it is ametropia, being corrected it is to be appreciated, however, that such is rectified precisely with overall ametropia of eyes, for angle
Uneven equal higher order aberratons existing for film surface not can be carried out correction.
The embodiments of the present invention relate in one aspect to a kind of eyeglass, and in conjunction with shown in Fig. 3, Fig. 4, which includes mirror
The inside of piece ontology 01, eyeglass ontology 01 is equipped with a free form surface 02, and the curvature on 02 surface of free form surface is arranged to cornea
The curvature on surface enables the free form surface to offset the irregular of anterior corneal surface and the aberration of generation.
The curvature of anterior corneal surface has otherness between individual patients, and therefore, above-mentioned free form surface is personalized customization.
The refraction for irregularly causing light of anterior corneal surface be also it is irregular, according to irregular cornea feature, the utility model is logical
It crosses and customizes the eyeglass of irregular free form surface and carry out the correction of irregular light, and for lenticular correction and angle will be directed to
The correction of film surface combines, and realizes more accurate correction.
The free form surface 02 can be arranged on the inside of above-mentioned eyeglass ontology 01, or it is understood that the free form surface
02 can also be arranged on the outside of above-mentioned eyeglass ontology, then it is understood that in conjunction with Fig. 5, which can also be with
It is arranged on the inner side and outer side of above-mentioned eyeglass ontology simultaneously；Inside described above, outside are to wear for eyes
After glasses, eyeglass ontology is inside close to eyes side, and the other side is outside.
Eyeglass ontology can be plane mirror；Alternatively,
Eyeglass ontology can have certain diopter in itself, to correct lenticular diopter；It such as can be biography
Near-sighted glasses, presbyopic glasses of system etc., in this case, the eyeglass ontology correct low order aberration, due to free form surface
Curvature is arranged to the curvature of personalized cornea, which can correct the higher order aberratons of cornea itself, reaches
The complicated ametropia problem of correction.
In present embodiment, the eyeglass is to be integrally formed to make by 3D printing；In order to realize the preparation of customization,
Used 3D printing equipment can be SLA, the equipment such as DLP.
3D printing at present is a kind of reliable technology of preparing, and 3D printing technique is to start the 1980s to lead in manufacturing industry

The data such as calculation machine tomoscan are accumulated by the accurate 3D of material, the new digital chemical conversion of the arbitrarily complicated 3D object of quick Fabrication
Type technology.The characteristics of 3D printing technique is the building that can quickly realize Arbitrary 3 D structure, and this exactly customizes individual character
Manufacturing process urgently needed for product.Present embodiment realizes eyeglass described in the utility model by 3D printing, is vast dioptric
Not positive patient brings more comfortable, accurate, clear completely new visual experience.
Preferably, 3D printing the selection of material is photocurable resin material.
On the other hand the embodiments of the present invention also disclose the production method of above-mentioned eyeglass:
The diopter of eyes is obtained, the diopter of eyeglass ontology itself is arranged to the diopter of the eyes, obtains mirror
The surface equation F1 (X, Y, Z)=0 of piece ontology itself；
Obtain the surface equation F2 (X, Y, Z)=0 of anterior corneal surface；
The curved surface F2 is amplified into the surface curved surface F1 that is added to, obtains curved surface F3 (X, Y, Z)=0；
According to curved surface F3, the eyeglass is obtained using 3D printing.
Wherein, it is to be understood that the diopter of the eyes can be obtained by traditional optometry means, in turn, the curved surface side
Its actually surface equation of conventional myopic mirror or presbyopic glasses of journey F1；
A kind of preferred embodiment is that the surface equation F2 of the anterior corneal surface can specifically be obtained by following methods:
Longitudinal section scanning is carried out to cornea by cornea OCT, the point set fitting that scanning is obtained is surface equation
F2 (X, Y, Z)=0.
It is understood that the number of plies of use is more in above-mentioned tomoscan, the curved surface F2 being fitted is closer to cornea
Surface；In the application, the tomoscan is to take 30~60 layers of tomography scanning, preferably takes 50 layers of tomography scanning.
Using the above method, obtained eyeglass while the higher order aberratons with lenticular diopter and canthus film surface,
Realize more accurate correction.
In another preferred embodiment, the surface equation F2 of the anterior corneal surface can also be obtained by following methods:
Cornea is scanned by corneal topography；The reconstruction of cornea 3D model is carried out according to scan image, thus
Obtain the toroidal function equation F2 of anterior corneal surface；
Using the above method, obtained eyeglass while there is the diopter of eyes and the higher order aberratons of canthus film surface, it is real
More accurate correction is showed.
In this implementation method, the eyeglass is to be integrally formed to make by 3D printing, specifically:
Toroidal function is added to after eyeglass ontology, the 3D function of the available eyeglass obtains mirror by 3D printing
Piece.
In addition, the embodiment of the present application also discloses a kind of pad pasting of free form surface, which has as described above
Free form surface 02, the other side are attached on the outside of conventional lenses, conventional spectacle lens can be made easily to compensate anterior corneal surface and caused
Irregular aberration, realize the complicated ametropic purpose of correction.
Preferably, the pad pasting is to be integrally formed to make by 3D printing.
The utility model personalized customization glasses can correct everyone different aberration, even if patient has irregular picture
Difference, we can accurately obtain parameter and the correction of irregular aberration, and patient's vision correction is made to reach perfect condition；Meanwhile 3D
Printing technique can fast and accurately customize personalized glasses, can solve the insurmountable problem of clinically common spectacles.
The foregoing is merely the preferred modes of the utility model, are not intended to limit the utility model, all practical new at this
Within the spirit and principle of type, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
