Abstract

本眼镜最优低像差防近视雾视球面镜，主要用于预防近视，也可用于减小老花镜的成像扭曲。它是利用医学上普遍认可的“雾视法”减小晶状体的负担来防近视的。本眼镜能严格控制像差，避免成像扭曲，并根据不同人的不同的生理状况与用眼习惯而选择不同的最优设计方案，而且将使用镜片的成本降低到原来的一半。制作时不仅将光心内移，而且创造性地将光心下移(定量化的)，下移后可在一个圆镜片切下制作一副眼镜所需要的两个镜片。

Description

最优低像差防近视雾视球面镜
技术领域
本眼镜主要用于预防近视，它是利用医学上普遍认可的“雾视法”，通过用凸透镜分担晶状体的一部分曲率，使人戴上后看近处(如看书)时，眼睛却处于晶状体极为放松的看远处时的状态，从而能从根本上防止近视的产生与遏止近视的加深。
背景技术
雾视法早已得到了医学上的普遍认可。大概十年前有人也发明了偏中心近视防治镜，大体解决了戴上雾视镜后集合和调节失衡的矛盾。然而他却因为没有解决镜片光心内移后像差(包括成像扭曲与两眼成像大小的差异)增大的问题而最终放弃了专利。目前偏中心主要还只是理论上的，真正实现起来还有些困难。
发明内容
我提出了一个新理论，认为戴上雾视镜或老花镜后会感到头晕，主要不是因为通常认为的那样是由于集合和调节的失衡，而是因为类似于恐高症那样的由于成像扭曲而导致的视觉平衡的丧失。这已经通过光心下移的实验得到了证实。本眼镜不仅将光心内移，而且创造性地将光心下移，使远处射来的光更多受到向上的弯折，从而在很大程度上避免了成像扭曲。本眼镜还能严格控制像差，根据不同人的不同的生理状况与用眼习惯而选择不同的最优设计方案，而且将使用镜片的成本降低到原来的一半，使雾视镜真正达到了实用阶段。
具体实施方式
设想眼镜是按正常的方位戴着的，在制作眼镜的过程中，不仅将镜片的光心向镜框中心移动，而且向下移动。当镜片光心下移时，光心就不再使用了，因此一个圆镜片就能切下制作一副眼镜所需要的两个镜片。
比如，现有折射率为1.499、直径为70mm的各种度数的镜片。一个没有近视、两眼瞳距为60mm的人，看书平均距离为30cm，给他配+2.00D的镜片后，光心需要在离镜框竖直中心线24.5mm处，并下移18.1mm。当他看30cm远处时，他感觉上是距离是31.9cm，向左或右偏离两眼正前方4cm处的物体在两眼内成像大小的相对差别为4.4％。这些数据是通过我编写的计算机程序严格计算得到的，而且这种设计是针对此人雾视球面镜能有的最优设计，但是计算相当复杂，而且与我要求保护的专利权项无关，故在此省略。

Claims (1)

  1. 本发明要求保护的技术特征为：一种镜片为凸透镜的眼镜(包括雾视镜与老花镜)，按正常的方位戴上这种眼镜并抬头正视前方后，光心向下偏离最常用视线与镜片的交点所在水平面(即光心下移)超过2mm。
