技术领域technical field
本实用涉及眼睛视力校正技术领域，具体属于一种双层镜片变焦眼镜。The utility model relates to the technical field of eyesight correction, in particular to double-layer lens zoom glasses.
背景技术Background technique
对于大多数人来说，在50岁左右时就需佩戴眼镜校正近视力。对年轻时就是近视眼的同志尤其是从事教育工作的教师表现得更为突出。这些人们在工作中频繁地摘带掉换眼镜给工作带来很大不便，人们一直在受到这样的困扰，直到美国发明家本杰明·富兰克林发明了双光眼镜为止。从1775年直到今天，双光眼镜的基本原理都没有变过，依然是将两种折射率不同的镜片上下接合或者熔合在一片镜片上，以缩小一半视野的代价来换取不必换眼镜的便利。抬眼看山低眼看报，已经是我们对这种眼镜的固有印象。但是这种眼镜因过小的视野让人们不得不频繁移动脑袋，会让一些人头昏眼花甚至头痛，存在许多问题。For most people, glasses are needed to correct near vision around the age of 50. It is more prominent for comrades who were short-sighted when they were young, especially teachers who are engaged in education. These people take off and take off and change glasses frequently in work and bring great inconvenience to work, and people have been suffering from such troubles until American inventor Benjamin Franklin invented bifocal glasses. From 1775 to today, the basic principle of bifocal glasses has not changed. It is still the upper and lower joints or fusion of two lenses with different refractive indices on one lens, and the cost of reducing the field of view by half is exchanged for the convenience of not having to change glasses. Looking up at mountains and looking down at newspapers is already our inherent impression of this kind of glasses. However, due to the small field of view of this kind of glasses, people have to move their heads frequently, which can cause some people to feel dizzy or even have a headache, and there are many problems.
人们对研制能够改变焦距的眼镜一直没有停止过，并且已经做了许多尝试。到2011年PixelOptics公司的emPower液晶变焦眼镜在研发12年、提出了275项专利申请后诞生了，然而它也存在一些问题：比如成本高的问题，它的售价在6000—14000人民币。People have never stopped developing glasses capable of changing the focal length, and many attempts have been made. By 2011, PixelOptics' emPower liquid crystal zoom glasses were born after 12 years of research and development and 275 patent applications. However, it also has some problems: such as the problem of high cost, and its price is 6000-14000 RMB.
实用新型内容Utility model content
本实用新型的目的在于提供一种结构简单、制作成本低的双层镜片变焦眼镜。The purpose of the utility model is to provide a double-lens zoom glasses with simple structure and low manufacturing cost.
本实用新型根据多镜片曲率(屈光度)叠加原理，在双层眼镜架的基础上，提出一种双层镜片变焦眼镜的技术方案。According to the principle of multi-lens curvature (diopter) superimposition, the utility model proposes a technical scheme of double-layer lens zoom glasses on the basis of a double-layer spectacle frame.
本实用新型提供的一种双层镜片变焦眼镜，包括主镜片架和活动镜片架，主镜片架和活动镜片架上分别安装有镜片；The utility model provides a kind of double-layer lens zoom glasses, which comprises a main lens frame and a movable lens frame, lenses are respectively installed on the main lens frame and the movable lens frame;
所述的主镜片架上安装的镜片的屈光度等于人的近视力矫正所需的屈光度；The diopter of the lens installed on the main lens frame is equal to the diopter required for people's near vision correction;
所述的活动镜片架上安装的镜片的屈光度等于人的远视力矫正所需的屈光度减去主镜片架上安装的镜片的屈光度。The diopter of the lens mounted on the movable lens frame is equal to the diopter required for human distance vision correction minus the diopter of the lens mounted on the main lens frame.
所述的镜片材料可以是水晶、玻璃、塑料等各种透明材料。The lens material can be crystal, glass, plastic and other transparent materials.
本实用新型在主镜片架和活动镜片架的底框某一相对应位置上分别镶嵌有1mm×2mm×1mm的钕铁硼永磁体，用于活动镜片架放下时与主镜片架吸合在一起。In the utility model, a 1mm×2mm×1mm NdFeB permanent magnet is respectively inlaid on a corresponding position of the main lens frame and the bottom frame of the movable lens frame, and is used for attracting together with the main lens frame when the movable lens frame is put down. .
与现有技术相比本实用新型的有益效果：Compared with the prior art, the utility model has the beneficial effects:
本发明根据多镜片聚焦(曲率)叠加原理，在双层眼镜架的基础上，提出一种双层镜片变焦眼镜的技术方案，它制作成本低、使用方便、适用于中老年尤其适用于年轻时是近视眼的从事教育工作的中老年教师在工作生活中使用。According to the principle of multi-lens focus (curvature) superposition, the present invention proposes a technical scheme of double-layer lens zoom glasses on the basis of a double-layer spectacle frame. It is used by middle-aged and elderly teachers who are engaged in education with myopia in their work and life.
