Embodiment
For above-mentioned purpose of the present invention, characteristic sum feature can be become apparent, accompanying drawing is hereby coordinated related embodiment of the present invention to be described in detail as follows.
Fig. 1 is the cross-sectional schematic of the contact lenses of one embodiment of the invention, and Fig. 2 is the front-view schematic diagram of the contact lenses of one embodiment of the invention.Please refer to Fig. 1 and Fig. 2, these contact lenses 100 comprise optical bodies 110 and a metal gate 120.This metal gate 120 is configured in this optical bodies 110, and comprises multiple metal membrane line 121, and those metal membrane lines 121 are parallel to each other.Please refer to Fig. 3, those metal membrane lines 121 define a grid surface 122, when a non-polarized light 130 this grid surface 122 incident, this grid surface 122 in order to the light (that is horizontal polarization light 132:spolarization) of the reflection polarized state parallel with this grid surface 122, and in order to penetrate the light (that is vertical polarization light 134:ppolarization) of 122 vertical polarized states surperficial with these grid.
Refer again to Fig. 1, this optical bodies 110 comprises the first noumenon 111 and one second body 112, and this metal gate 120 is configured on this first noumenon 111, and this second body 112 covers this metal gate 120 and this first noumenon 111.The width W 1 of those metal membrane lines 121 can be 100 ~ 200nm, can the light (its wavelength is 400 ~ 700nm) of the usable reflection polarized state parallel with this grid surface 122.It is made that those metal membrane lines 121 can be silver.It is made that this optical bodies 110 can be glass, polymethylmethacrylate (PMMA), gas penetration potential half hard lens (RGP), poly hydroxy ethyl acrylate (HEMA), silicon glue (SiliconHydrogel) etc.
In detail, this the first noumenon 111 comprises multiple strip recessed surperficial 113 and multiple strip nonreentrant surface 114, this strip recessed surperficial 113 and this strip nonreentrant surface 114 sequential, those metal membrane lines are configured on those strip nonreentrant surfaces 114, and this second body 112 covers those metal membrane lines 121 and those strips recessed surperficial 113.Concaveconvex structure adds that double-decker (core dielectric material and outer layer metal material) can make vertical polarization light transmittance promote, also can promote the blocking effect of horizontal polarization light simultaneously, when particularly the height H of those strip nonreentrant surfaces 114 is 100 ~ 300nm, best effect can be had.The width W 2 of those strip nonreentrant surfaces 114 can be 100 ~ 200nm, and the recessed width of surperficial 113 of those strips can be 100 ~ 200nm.
Please refer to Fig. 4, these contact lenses 100 are in order to wear on an eyeball 102, and those metal membrane lines 121 are parallel to each other in the horizontal direction substantially.This optical bodies 110 comprises the first half 116 and a Lower Half 115, and the weight of this Lower Half 115 is greater than the weight of this first half 116, makes this optical bodies 110 have asymmetric structural design.Such as, the thickness by this Lower Half 115 of design is greater than the thickness of this first half 116, makes the weight of this Lower Half 115 be greater than the weight of this first half 116.Because this optical bodies 110 has asymmetric structural design, gravity after therefore wearing, can be utilized automatically to go to weight balancing the correct direction coordinating eyeball 102.Moreover the dissymmetrical structure of this optical bodies 110 optically just can coordinate the asymmetric of eyeball 102, does the optimization of lens error correction.
Contact lenses of the present invention is a kind of novel invention, and it has the structural design of metal gate, can reach reflective polarizer effect, there is no a large amount of chemical composition and causes damage to human body.Dazzle light except reflecting, and there is certain light transmission.The structure of metal gate can be interlayer, and during to prevent from wearing, hand touches this metal gate, inserts will affect its performance by water or oil stain.Characteristic of the present invention is: 1. have reflecting type polarizing effect, reduces sunshine to the injury of eyeball.2. increase user attractive in appearance, must additionally not wear glasses.3. reflecting type polarizing effect can reduce the heat energy absorbing light source and produce.
Fig. 5 is the process flow diagram of the contact lenses manufacture method of one embodiment of the invention.This crowded type method comprises the following step:
In the step s 100, please refer to Fig. 6, form a first noumenon 111.Citing, (inside surface of ejection shaping die has the microstructure of the recessed surface of multiple strip and multiple strip nonreentrant surface to utilize jetting formation process, figure does not show), this the first noumenon 111 transfer printing can be formed with microstructure, this strip recessed surperficial 113 and this strip nonreentrant surface 114 sequential of multiple strip recessed surperficial 113 and multiple strip nonreentrant surface 114.
In step s 110, please refer to Fig. 7, a metal gate 120 is configured on this first noumenon 111.Citing, utilizes sputter, micro-shadow and etch process, is formed by multiple metal membrane lines 121 of this metal gate 120 and be configured on those strip nonreentrant surfaces 114.
In the step s 120, one second body 112 is covered this metal gate 120 and this first noumenon 111, as shown in Figure 1.Citing, utilizes another jetting formation process, this second body 112 is covered those metal membrane lines 121 of this metal gate 120 and those strips recessed surperficial 113 of this first noumenon 111.This first noumenon 111 and this second body 112 are combined into an optical bodies 110, this metal gate 120 is configured in this optical bodies 110, those metal membrane lines 121 of this metal gate 120 are parallel to each other, those metal membrane lines 121 define a grid surface, in order to reflect the light of the polarized state parallel with this grid surface, and in order to penetrate the light of the polarized state vertical with this grid surface.
In addition, this jetting formation process can comprise shaping deburring and aquation is checked the quality.Shaping deburring is carried out in the such as high toilet of 100,000 grades etc., makes lens edge tool high smoothness.Come off on mould after making lens hydration with liquid parting again, finally carry out eyeglass quality restriction, lens disinfection and packaging shipment.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
