应当可以理解的是，虽然本文中可能会使用到“第一”、“第二”、“第三”等术语来描述各种组件或者信号，但这些组件或者信号不应受这些术语的限制。这些术语主要是用以区分一组件与另一组件，或者一信号与另一信号。另外，本文中所使用的术语“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。
[实施例一]
请参阅图1至图9所示，其为本发明的实施例一。如图1至图4所示，本实施例公开一种隐形眼镜100(或称为智能隐形眼镜)。其中，所述隐形眼镜100可以依据设计需求而配戴于使用者的眼睛200上(如：图3)或是埋置于所述眼睛200内(图中未示出)。
再者，所述隐形眼镜100于本实施例中可以具有矫正屈光不正(refractive error)的功能，并且所述屈光不正包含远视(hyperopia)、近视(myopia)、散光(astigmatism)、或老花眼(presbyopia)、或散光老花眼(astigmatism-presbyopia)；或者，所述隐形眼镜100可以是没有矫正功能的化妆(makeup)镜片。
所述隐形眼镜100于本实施例中包含有一眼镜本体1、埋置于所述眼镜本体1内的一电子元件2及埋置于所述眼镜本体1内且电性耦接于所述电子元件2的一线路结构3，但本发明不受限于此。举例来说，在本发明未示出的其他实施例中，所述隐形眼镜100也可以依据设计需求而仅包含所述眼镜本体1与所述线路结构3、而省略所述电子元件2。以下将依序说明本实施例的所述隐形眼镜100的各个构件，并适时介绍多个构件之间的连接关系。
所述眼镜本体1于本实施例中是经由水胶(hydrogel)或硅水胶(silicone hydrogel)固化而形成，并且上述水胶例如是p-HEMA，但不以此为限。其中，所述眼镜本体1包含有一光学部11及围绕于所述光学部11的一环形配戴部12，所述光学部11可以依据设计需求而构成具备或不具备矫正所述屈光不正的功能。需说明的是，所述光学部11于本实施例中虽不埋置有任何组件，但其可根据设计需求(例如：所述隐形眼镜100应用在数字变焦装置)，而在所述光学部11内埋置组件，不受本实施例上述记载所限制。
再者，所述光学部11定义有一中心轴线L，并且所述光学部11的中心与所述环形配戴部12的中心皆坐落在所述中心轴线L之上。其中，所述环形配戴部12是相连于所述光学部11的外边缘且大致呈圆环状，并且所述环形配戴部12的内部埋置有所述电子元件2与所述线路结构3。此外，有关将所述电子元件2及所述线路结构3埋置于所述环形配戴部12的生产方式(或是所述隐形眼镜100的制造方法)可以依据设计需求而加以调整变化，本发明在此不加以限制。
更详细地说，所述环形配戴部12具有呈C字形的一布局区121及位于所述布局区121的两个末端之间的一下眼睑区122，并且所述电子元件2埋置于所述下眼睑区122之内。其中，当所述隐形眼镜100配戴于所述眼睛200时，所述下眼睑区122与所述电子元件2的位置是对应于所述眼睛200较为不敏感的下眼睑201之内，据以有效地降低所述使用者的异物感。
换个角度来说，如图2至图5所示，所述眼镜本体1的表面包含有一后表面1b及位于所述后表面1b相反侧的一前表面1a。其中，所述后表面1b具有一预设曲率，其适于配戴在所述使用者的所述眼睛200；也就是说，所述预设曲率的数值仅相关于所述眼睛200。
再者，所述前表面1a具有对应于所述光学部11的一可视面11a及对应于所述环形配戴部12的一自由曲面12a，并且所述可视面11a具有一第一曲率，其相关于矫正所述屈光不正所需要的光学设计；或者，所述可视面11a的所述第一曲率也可以和所述后表面1b共同构成没有度数的构造。
进一步地说，所述可视面11a的所述第一曲率不同于所述自由曲面12a的一第二曲率，以使所述环形配戴部12的厚度分布是朝向所述电子元件2(如：所述下眼睑区122)呈现逐渐递增状。也就是说，具有大致相等厚度的配戴部的隐形眼镜则不同于本实施例所指的所述隐形眼镜100。
换个角度来说，所述隐形眼镜100可根据设计需求而在所述环形配戴部12的任意部位埋置有至少一个所述电子元件2；举例来说，在本发明未示出的其他实施例中，所述环形配戴部12于其水平两侧各埋置有至少一个所述电子元件2，以使所述环形配戴部12的厚度在眼睛的水平方位最厚，且其朝向眼睛的铅锤方位逐渐地变薄；据此，此设置方式可容纳至少两组所述电子元件2，并可降低所述隐形眼镜100的配戴异物感。
依上所述，本发明实施例所公开的所述隐形眼镜100，其通过所述眼镜本体1的所述前表面1a形成有所述自由曲面12a，以使所述布局区121的厚度无须完全迁就所述下眼睑区122的厚度，进而实现所述布局区121的薄型化，据以有效地提升所述布局区121的透氧率、并降低所述隐形眼镜100的配戴异物感。
为了更有效地提升所述布局区121的所述透氧率、并降低所述隐形眼镜100的配戴异物感，所述隐形眼镜100较佳是通过所述自由曲面12a的所述第二曲率调配，以具备有下述两段内容中的多个特征的至少其中之一，但本发明不以此为限。
所述环形配戴部12(埋置有构件的部位)的最大厚度Tmax是落在所述电子元件2所在的区域(如：所述下眼睑区122)，并且所述环形配戴部12(埋置有构件的部位)的最小厚度Tmin则是落在远离所述下眼睑区122的所述布局区121的一部位(如：图4中的所述布局区121顶部)。也就是说，当所述隐形眼镜100配戴于所述眼睛200时，所述环形配戴部12(埋置有构件且)具有所述最大厚度Tmax的部位是对应位于所述眼睛200的所述下眼睑201之内，而所述环形配戴部12(埋置有构件且)具有所述最小厚度Tmin的该部位是对应位于所述眼睛200的所述上眼睑202之内。所述最大厚度Tmax与最小厚度Tmin于本实施例中虽是对应于使用者的下眼睑与上眼睑，但本发明并不以此限制所述隐形镜片100厚度与用户眼睑的相对位置关系。
再者，所述线路结构3于所述下眼睑区122是与所述后表面1b相隔有一距离D122，其大于所述线路结构3于所述布局区121与所述后表面1b所相隔的距离D121。
所述线路结构3可以于所述眼镜本体1内单独地存在(图中未示出)或是搭配所述电子元件2，进而由通电驱动或是物理性驱动，以实现能量接收、无线信号传输、数字计算、感测监控、施加压力、电流释放、图像投射、光学变焦及储存电力等多个功能的至少其中之一，但本发明不以此为限。
所述线路结构3于本实施例中包含一载板31及形成于所述载板31的一线路32(如：金属线路)，并且所述线路32连接于所述电子元件2而彼此电性耦接。于本实施例中，所述载板31可以通过压合模具的常温加压或高温加压，而定型为一预设曲形构造，以使所述载板31具有不同于所述第二曲率的一定型曲率，并且所述定型曲率较佳是相近于所述后表面1b的所述预设曲率(如：所述定型曲率为所述预设曲率的100％～110％)，但本发明不以上述为限。
其中，所述载板31于本实施例中是以厚度介于10微米～300微米的一可挠性印刷电路板(flexible printed circuit board，FPCB)来说明，并且所述载板31的厚度较佳是介于40微米～80微米，而所述载板31具有的高分子材料可以包含有聚酰亚胺(Polyimide，PI)、液晶高分子(Liquid-crystal polymer，LCP)、聚对苯二甲酸乙二酯(Polyethylene terephthalate，PET)、或聚萘二甲酸乙二醇酯(Poly(ethylene 2,6-naphthalene dicarboxylate)，PEN)，但不以上述为限。
更详细地说，所述载板31具有埋置于所述布局区121的一C形段311及埋置于所述下眼睑区122的一连接段312，并且所述连接段312相连于所述C形段311的两个末端缘之间。其中，所述电子元件2可以是安装于所述连接段312，所述线路32则是形成于所述C形段311、并延伸至所述连接段312以连接于所述电子元件2。
再者，基于所述载板31容易在加压成形的过程中产生皱折或应力集中的情况，所述C形段311形成有至少一个贯穿孔3111，并且所述眼镜本体1填满至少一个所述贯穿孔3111。需注意的是，在(沿着所述中心轴线L的)所述隐形眼镜100的俯视图之中，至少一个所述贯穿孔3111的面积需要是占据所述C形段311的外轮廓所包围的面积的1％～85％(较佳为10％～40％)，据以有效地降低所述载板31产生皱折或应力集中的情况、并能与所述自由曲面12a相互搭配而进一步提升所述隐形眼镜100的透氧率。
此外，所述载板31也可以自其外边缘朝向所述中心轴线L形成有多个径向切痕313，据以进一步降低所述载板31产生皱折或应力集中的情况。其中，多个所述径向切痕313于本实施例中是分别形成于所述C形段311与所述连接段312的交界处，但本发明不受限于此。
再者，在所述隐形眼镜100的所述俯视图之中，至少一个所述贯穿孔3111的所述面积占据所述环形配戴部12的面积的1％～75％，而形成于所述C形段311的至少一个所述贯穿孔3111数量于本实施例中是以多个来说明，但本发明不受限于此。举例来说，在本发明未示出的其他实施例中，所述载板31的所述C形段311也可以不形成有任何贯穿孔3111。
于本实施例中，所述线路32包围形成有至少一个封闭回路，并且所述C形段311的多个所述贯穿孔3111位于所述线路32的至少一个所述封闭回路之内。需说明的是，至少一个所述封闭回路的数量于本实施例中是以多个来说明，并且多个所述贯穿孔3111分别位于所述线路32的多个所述封闭回路之内，但本发明不以此为限。
其中，每个所述贯穿孔3111呈曲线状，并且任一个所述贯穿孔3111的宽度自其两端朝中央呈渐增状(如：所述贯穿孔3111于本实施例中大致呈弦月状)。更详细地说，任一个所述贯穿孔3111具有一内孔缘3112与一外孔缘3113，并且所述内孔缘3112的两端分别相接于所述外孔缘3113的两端，以分别构成至少一个所述贯穿孔3111的所述两端。
其中，所述内孔缘3112与所述外孔缘3113皆呈圆弧状，并且所述内孔缘3112的半径小于所述外孔缘3113的半径，而所述内孔缘3112的中央与所述外孔缘3113的中央分别位在垂直所述中心轴线L的不同两个平面之上；也就是说，每个所述贯穿孔3111于本实施例中是沿着所述载板31的所述定型曲率配置、而非为平面状。
为便于更为清楚地界定多个所述贯穿孔3111的分布情况，在所述隐形眼镜100的所述俯视图之中，所述中心轴线L定义为一原点，并且依据所述原点定义有交叉于所述原点且相互垂直的一X轴与一Y轴，据以沿逆时针方向依序划分出一第一象限Q1、一第二象限Q2、一第三象限Q3及一第四象限Q4。
在所述隐形眼镜100的所述俯视图之中，所述下眼睑区122位于所述第三象限Q3与所述第四象限Q4，并且所述Y轴大致是所述下眼睑区122的中分线，而所述下眼睑区122对应于所述原点的一圆心角σ122，其较佳是介于30度～180度之间，并且所述圆心角σ122的数值可依设计需求而定，本发明不受限于此。
再者，于所述隐形眼镜100的所述俯视图之中，多个所述贯穿孔3111分布于所述第一象限Q1、所述第二象限Q2、所述第三象限Q3及所述第四象限Q4，并且分布于所述第一象限Q1、所述第二象限Q2、所述第三象限Q3及所述第四象限Q4的多个所述贯穿孔3111的多个部位，其任两个所述部位之间的面积差异不大于50％。
更详细地说，于所述隐形眼镜100的所述俯视图之中，任一个所述贯穿孔3111是横跨至少两个象限(如：任一个所述贯穿孔3111位于所述第一象限Q1与所述第四象限Q4之内、或是位于所述第二象限Q2与所述第三象限Q3之内)，并且任一个所述贯穿孔3111可以是镜像对称于所述X轴，但本发明不受限于此。
多个所述贯穿孔3111包含有至少一个第一贯穿孔3111a与至少一个第二贯穿孔3111b，并且至少一个所述第一贯穿孔3111a的数量与至少一个所述第二贯穿孔3111b的数量于本实施例中各以多个来说明，但本发明不受限于此。其中，多个所述第一贯穿孔3111a分别位于多个所述第二贯穿孔3111b的内侧；也就是说，每个所述第二贯穿孔3111b的半径不同于(如：大于)任一个所述第一贯穿孔3111a的半径。
于本实施例中，每个所述第一贯穿孔3111a呈圆弧状且圆心坐落于所述中心轴线L之上，并且多个所述第一贯穿孔3111a彼此间隔配置，每个所述第二贯穿孔3111b呈圆弧状且圆心坐落于所述中心轴线L之上，并且多个所述第二贯穿孔3111b彼此间隔配置。
再者，任一个所述第一贯穿孔3111a位于相对应所述第二贯穿孔3111b的圆心角范围之内，并且任两个相邻的所述第一贯穿孔3111a之间的间隔部位，其与任两个相邻的所述第二贯穿孔3111b之间的间隔部位是位于所述隐形眼镜100的同一径向之上。
如图2、图4及图6所示，所述环形配戴部12具有自所述前表面1a与所述后表面1b至少其中之一朝向所述线路结构3凹设所形成的多个定位槽123，并且每个所述定位槽123的底缘包含有所述线路结构3的局部，以使所述线路结构3的所述局部裸露于外，但本发明不以此为限。举例来说，在本发明未示出的其他实施例中，所述环形配戴部12也可以依据设计需求而仅形成一个所述定位槽123、或是不形成任何所述定位槽123。
更详细地说，当所述线路结构3(及所述电子元件2)设置于一成型模具(图中未示出)之内时，所述成型模具的多个定位结构抵靠于所述线路结构3的所述局部，以精准地定位所述线路结构3(及所述电子元件2)至一预定位置，进而利于在所述成型模具内灌注且固化形成包覆所述线路结构3(及所述电子元件2)的所述眼镜本体1。其中，所述隐形眼镜100在自所述成型模具取出之后，先前包覆于多个所述定位结构的所述眼镜本体1部位则形成有多个所述定位槽123。
依上所述，本发明实施例所公开的所述隐形眼镜100，其通过所述环形配戴部12在规划其构型时就留有多个所述定位槽123，以利于所述隐形眼镜100在生产制造的过程中能实现所述线路结构3(与所述电子元件2)的高精度定位，据以使得所述隐形眼镜100于量产时保有高度一致性。
其中，多个所述定位槽123能被控制在一定的比例范围之内(如：多个所述定位槽123的槽口所包围的面积总和，其不大于所述前表面1a与所述后表面1b的表面积总和的1％)，据以避免过度影响所述隐形眼镜100的强度。再者，所述线路结构3还通过其所述局部裸露于相对应所述定位槽123之外，以提升其散热效果。
进一步地说，如图4至图9所示，多个所述定位槽123于本实施例中可以区分为多个前定位槽123a以及所述后定位槽123b，并且多个所述前定位槽123a是自所述前表面1a(如：所述自由曲面12a)朝向所述线路结构3凹设所形成，而所述后定位槽123b则是自所述后表面1b朝向所述线路结构3凹设所形成，但本发明不以此为限。
每个所述后定位槽123b的底缘及/或每个所述前定位槽123a的底缘可能包含所述线路结构3的局部，以使所述线路结构3的所述局部裸露于外。其中，多个所述前定位槽123a的深度各介于50微米(μm)～100微米，并且多个所述后定位槽123b的深度各介于50微米～100微米。也就是说，所述隐形眼镜100于本实施例中通过所述前定位槽123a与所述后定位槽123b的所述深度的规划，进而能精准地使所述线路结构3埋置于所述眼镜本体1的预定深度之处。此外，上述预定深度可依设计需求而定，本发明不以此为限。
多个所述后定位槽123b于本实施例中较佳是不与任一个所述前定位槽123a对应于所述线路结构3的相同部位，据以通过彼此错位配置的方式来构成多点定位的效果，进而利于实现所述线路结构3的高精度定位，并且有效地避免所述隐形眼镜100产生局部强度不足的情况。此外，在所述隐形眼镜100的所述俯视图之中，所述后定位槽123b与所述前定位槽123a各可以是沿着所述眼镜本体1的径向延伸所形成并跨越所述线路结构3，但本发明不受限于此。
更详细地说，所述前定位槽123a于本实施例中是大致呈阶梯状构造，并且所述前定位槽123a具有一第一阶面1231、相连于所述前表面1a(如：所述自由曲面12a)与所述第一阶面1231之间的一第一梯面1232、间隔于所述第一阶面1231的一第二阶面1233及相连于所述第一阶面1231与所述第二阶面1233之间的一第二梯面1234。
其中，所述第一阶面1231位于所述前定位槽123a的所述底缘，并且所述第一阶面1231包含所述线路结构3的所述局部，以裸露所述线路结构3的所述局部。所述第二阶面1233与所述前表面1a(如：所述自由曲面12a)之间的距离大于所述第一阶面1231与所述前表面1a(如：所述自由曲面12a)之间的距离。再者，所述第二梯面1234位于所述线路结构3(或电子元件2)的一侧，而所述线路32完全埋置于所述眼镜本体1之内；也就是说，所述线路结构3可以是仅以所述载板31的局部自所述定位槽123裸露于外。
需额外说明的是，多个所述前定位槽123a的具体构造与形状可以依据设计需求而加以调整变化，并且多个所述前定位槽123a于本实施例中也采用多种不同的构造(如：图4和图8)，据以利于实现所述线路结构3的高精度定位。
进一步地说，位于所述下眼睑区122的任一个所述前定位槽123a的深度，其大于位于所述布局区121的任一个所述前定位槽123a的深度。再者，位于所述下眼睑区122的其中一个所述前定位槽123a的所述底缘(或所述第一阶面1231)包含有所述电子元件2的局部，以使所述电子元件2的所述局部裸露于外，据以利于实现所述电子元件2的高精度定位。
需额外说明的是，所述隐形眼镜100于本实施例中可以进一步搭配于各式装置进行使用。举例来说，在本发明未示出的其他实施例中，所述隐形眼镜100可以无线连接于配戴在使用者身上的任何穿戴装置(如：安装于眼镜的读取器、或颈戴式读取器)，并且上述穿戴装置(或读取器)可采用常见无线传输技术RFID，例如13.56MHz或860-960MHz带宽，或其他无线感应电能、信号传输等技术，据以为所述隐形眼镜100进行供电、感测、或回馈信号，进而达到其智能监控(例如全时眼压数值收集与警示)、智能治疗(例如干眼症药物缓释控制)、AR服务(例如图像投影)、或其他智能应用。
[实施例二]
请参阅图10和图11所示，其为本发明的实施例二。由于本实施例类似于上述实施例一，所以两个实施例的相同处不再加以赘述，而本实施例相较于上述实施例一的差异大致说明如下：
于本实施例中，至少一个所述前定位槽123a可以是呈锯齿状且横跨多个所述贯穿孔3111，以使每个所述贯穿孔3111的局部裸露于外。其中，在所述隐形眼镜100的所述俯视图之中，呈锯齿状的所述前定位槽123a是沿着所述眼镜本体1的径向延伸所形成并跨越所述线路结构3；每个所述贯穿孔3111的所述局部的位置是对应于呈锯齿状的所述前定位槽123a的所述第一阶面1231与所述第二阶面1233之间。
更详细地说，于呈锯齿状的所述前定位槽123a之中，所述第一阶面1231与所述第二阶面1233各包含有彼此分离的多个区段，并且所述第一阶面1231包含所述线路结构3的所述局部，以裸露所述线路结构3的所述局部，所述第二阶面1233与所述前表面1a之间的距离大于所述第一阶面1231与所述前表面1a之间的距离，而所述第一梯面1232是相连于所述自由曲面12a与所述第二阶面1233。

再者，相邻的两个所述贯穿孔3111之间可以配置一个所述前定位槽123a，并且多个所述贯穿孔3111包含有多个第一贯穿孔3111a与多个第二贯穿孔3111b。其中，多个所述第一贯穿孔3111a分别位于多个所述第二贯穿孔3111b的内侧；也就是说，每个所述第二贯穿孔3111b的半径不同于(如：大于)任一个所述第一贯穿孔3111a的半径。
于本实施例中，每个所述第一贯穿孔3111a呈圆弧状且圆心坐落于所述中心轴线L之上，并且多个所述第一贯穿孔3111a彼此间隔配置，每个所述第二贯穿孔3111b呈圆弧状且圆心坐落于所述中心轴线L之上，并且多个所述第二贯穿孔3111b彼此间隔配置。
