 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
图1A和图1B分别为传统的太阳眼镜和3D眼镜的偏光特性，其中图1A中的I表示线偏光片层的光轴，其方向沿竖直方向，图1B中的II’和II”分别表示左眼、右眼的偏光方向。本发明基于两者的偏光特性，将二者予以组合，即本发明提供的镜片结构包括一四分之一波片层和一线偏光片层。
如图2A所示，此时的眼镜可作为3D眼镜使用,线偏光片层100位于内侧，即靠近眼睛的一侧，而四分之一波片层200位于远离眼睛的外侧，线偏光片层100的偏光轴方向为竖直方向。来自外界的3D影像最常用的是以圆偏振光方式来区隔左右眼图像，最终形成3D立体效果。不管是由电影院投影银幕反射过来的，或是由家庭立体电视屏幕直接放送出来的视频图像光线，左右图像都会用顺时针圆偏振光来放送一个眼睛的图像，同时用逆时针的圆偏振光来放送另外一个眼睛的图像，这一对左右图像互相配合，从两个不同的视点表达同一个场景带有视差的一对图像。具体到本发明所述的镜片结构，当四分之一波片层200朝外侧的时候，两个镜片形成圆偏振光的效用，一个镜片仅让顺时针的圆偏振光图像通过，另外一个镜片仅让逆时针的圆偏振光图像通过，让左右眼睛只看到相应的图像，不会产生左右串扰，使用者的脑部接收到有正确视差的一对图像，然后由人脑合成立体感的图像。
如图2B所示，将图2A所示的镜片沿竖直方向或水平方向翻转180度后即可作为太阳眼镜使用，此时，四分之一波片层200位于内侧，即靠近眼睛的一侧，而线偏光片层100位于远离眼睛的外侧，线偏光片层100的偏光轴方向仍为竖直方向。来自外界的太阳光线中最影响人视觉而且产生不舒服感觉的就是反光，无论是汽车挡风玻璃的反光、路面的反光、海上或水面上的反光，或者是沙滩上与及雪地上的反光，都会影响人的视觉不舒服，或是看不清楚眼前的景物。这些反光有一个共同的特点，就是有水平偏光的特性，这是因为经过镜面的固体或液体反光的时候，会使得反射出来的光产生偏光性，而且偏光轴都是以水平方向的为主。偏光式太阳眼镜就是用偏光轴竖直的偏光片，把这些反射出来的光过滤掉很高的百分比，让观察人可以更清晰的看到要看的景物。具体本发明所述的镜片结构，当线偏光片层100朝外的时候，就可产生同样的功能，首先线偏光片层100把水平方向的反光过滤掉，再通过四分之一波片层200到达人眼，此时四分之一波片层200对光线不进行光学作用。
上述图2A所示的实施方式中，当线偏光片层100位于靠近眼睛的内侧，而四分之一波片层200位于远离眼睛的外侧时，线偏光片层100的偏光轴方向是为竖直方向的，当然，线偏光片层100的偏光轴方向并不限于竖直方向，也可以是其他方向，只要能保证当线偏光片层100位于镜片远离眼睛的外侧时，线偏光片层100的光轴方向是沿竖直方向的即可。
例如，如图35A所示的另一种实施方式，其与图2A所示实施方式的主要区别在于线编光片层100’的偏光轴方向不同，图35A所示的实施方式中，当线偏光片层100’位于靠近眼睛的内侧，四分之一波片层200’位于远离眼睛的外侧时，线偏光片层100’的偏光轴方向为水平方向。这种状态下的眼镜也可以作为3D眼镜使用，其光学原理与上述图2A相同，在此不赘述。
将图35A所示的镜片沿与水平方向呈一角度的转轴旋转180度后得到另一种镜片方式，如图35B所示，此时的眼镜同样可作为太阳眼镜使用，四分之一波片层200’位于内侧，即靠近眼睛的一侧，而线偏光片层100’位于远离眼睛的外侧，线偏光片层100’的偏光轴旋转后由水平方向转成垂直方向，在本发明的实施例中，镜片沿与水平方向呈45度的转轴旋转。图35B所示状态下的眼镜的光学原理与上述图2B相同，在此不再赘述。
具体应用时，可采用上述镜片结构制作出镜片可翻转的两用眼镜，使用户在使用时可选择地将线偏光片层100或四分之一波片层200位于外侧，从而使该眼镜兼具太阳镜功能和3D眼镜功能。实现上述镜片翻转的方式可以有多种，以下结合附图举例说明本发明中两用眼镜的各种实施方式。
请参阅图3至图7，是本发明中两用眼镜的第一实施例，该两用眼镜包括镜框11、前述的镜片12及二镜腿13，镜片12与二镜腿13安装于镜框11上，并且镜片12与镜腿13可相对翻转。本实施例中，镜片12转动地安装于镜框11上，其转轴14水平地枢接于镜框11上。具体地，眼镜还包括镜片框15，镜片12固定安装于镜片框15上，转轴14从镜片框15上突伸而出。本实施例中，眼镜具有两个镜片框15，两个镜片12分别固定安装于两个镜片框15上，并可在竖直方向上独立转动。
作为上述实施方式的进一步改进，上述镜框11的内侧缘设有凹坑或凸起（本实施例中是凹坑111），镜片框15上对应凹坑或凸起的位置处设有与之相配合的凸起或凹坑（本实施例中是凸起151）。当镜片12旋转到位时，凸起151卡设于凹坑111内，从而使镜片12定位；需要转动镜片12时，用力推动镜片12，使凸起151受力发生轻微变形，即可解除定位。此外，镜片框15上凸设有推动块152，以便于用手推动镜片12。
请参阅图8至图12，是本发明中两用眼镜的第二实施例，本实施例与上述第一实施例的不同之处主要在于，本实施例中的眼镜具有一个镜片框15，镜片12固定安装于镜片框15上，并可在竖直方向上同步转动。
请参阅图13至图17，是本发明中两用眼镜的第三实施例，本实施例与上述第一实施例的不同之处主要在于镜片12的旋转方向，本实施例中的镜片12的转轴14竖直地枢接于镜框11上，镜片12可在水平方向上转动。
请参阅图18至图21，是本发明中两用眼镜的第四实施例，本实施例与上述第三实施例的不同之处主要在于，本实施例中的眼镜具有一个镜片框15，镜片12固定安装于镜片框15上，并可在水平方向上同步转动。
上述四个实施例中皆为镜片12可相对镜框11转动，当然，也可以是镜腿13相对镜框11转动，而镜片12可以不动。请参阅图22至图28，是本发明中两用眼镜的第五实施例，本实施例中的二镜腿13可转动地安装于镜框11上。镜腿13的一端具有一连接件16，连接件16在水平方向上可转动地枢接于镜框11上。连接件16包括主体161及二枢接轴162，二枢接轴162分别从主体161的两侧突伸而出，镜框11上具有分别与二枢接轴162相配合的枢接孔112。其中一个枢接轴162上具有向两侧延伸的突齿1621，与具有突齿1621的枢接轴162相配合的枢接孔112为台阶孔，且其形状与枢接轴162相对应。需要改变镜腿13的方向时，转动镜腿13，使枢接轴162上的突齿1621发生轻微变形，从而脱离与台阶孔的卡扣，当镜腿13旋转180度时，枢接轴162上的突齿1621重新卡设于台阶孔中，即可重新定位镜腿13。
进一步地，镜腿13可转动地枢接于连接件16上。镜腿13与连接件16的枢接部位套设有一定位套17，定位套17可在镜腿13上滑动，其内具有凸起或凹坑（本实施例中是凸起171），连接件16上对应凸起或凹坑的位置处设有与之相配合的凹坑或凸起（本实施例中是凹坑163）。凸起171与凹坑163相卡扣时，镜腿13在定位套17的限位作用下不能翻折；需要折叠镜腿13时，拨动定位套17，使凸起171发生轻微变形后与凹坑163脱离，当定位套17滑动到镜腿13上，并完全离开镜腿13与连接件16的枢接部位后，即可翻折镜腿13。
请参阅图29至图32，是本发明的第六实施例，本实施例与上述第五实施例的区别在于镜腿13的旋转方向不同，本实施例中，镜框11上突设有水平的枢接柱113，镜腿13在竖直方向上可转动地套设于枢接柱113上。需要改变镜腿13的方向时，在竖直方向上180度转动镜腿13后，上下颠倒眼镜，即可改变眼镜的功能。
作为本发明的又一应用方式，还可将上述镜片结构夹设于其他类型的眼镜外侧，如近视眼镜等。请参阅图33及图34，是本发明中两用眼镜的第六实施例，其包括前述的镜片12及定位夹18。定位夹18包括第一夹持部181及第二夹持部182，第一夹持部181用于夹持镜片12，第二夹持部182用于夹持另一眼镜（图中未示出）。本身佩戴有眼镜的人士佩戴本发明中的两用眼镜时，用第二夹持部182夹持住其自己的眼镜即可；需要改变眼镜的功能时，仅需将镜片12从第一夹持部181上取下变换正反面的方向后，重新夹持到第一夹持部181上即可。
作为本发明的再一实施方式，请参阅图36至图40，是本发明中两用眼镜的第八实施例，本实施例与上述各实施例的不同之处主要在于，本实施例中，镜片12的转轴14与水平方向呈45度角地倾斜枢接于镜框11上。具体地，眼镜还包括镜片框15，镜片12固定安装于镜片框15上，转轴14从镜片框15上突伸而出。本实施例中，眼镜具有两个镜片框15，两个镜片12分别固定安装于两个镜片框15上，并可分别沿转轴14独立转动。
综上所述，本发明所提供的镜片包括一四分之一波片层和一线偏光片层，调整本发明中镜片的方向，使四分之一波片层和线偏光片层中的任意一个均可位于镜片远离眼睛的外侧，并且当线偏光片层位于镜片远离眼睛的外侧时，线偏光片层的光轴沿竖直方向，即可制作兼具太阳镜功能和3D眼镜功能的两用眼镜。调整镜片的方向可以有多种实施方式，例如在竖直方向上设置转轴、或者在水平方向上设置转轴、或者在与水平方向呈一角度的倾斜方向上设置转轴等等，其转化操作简单方便，用户可跟根据需要自行调整镜片方向，选择使用相应的功能，与现有的功能单一的3D眼镜或太阳眼镜相比，一镜两用，实用性更强。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
