从前装枪问世至今的几百年间,枪械的结构和弹药有了巨大变化,枪械的性能有了很大提高,但瞄具的发展相对枪械本身来说进展十分缓慢。总的来讲,瞄准具与枪械性能是不匹配的。 机械瞄准具的缺陷 人眼晶体焦距的变化可使人眼看清大于1′视角的物体。但不同距离的物体不能同时在视网膜上成清晰的图像。人眼关注的物体看清楚了,其他距离上的物体就模糊,两个物体间的距 In the hundreds of years since the gun was first introduced, the structure and ammunition of firearms have changed dramatically. The performance of firearms has greatly improved. However, the development of aiming equipment has progressed very slowly with respect to the firearms themselves. In general, sights do not match gun performance. Mechanical sight defects Human eye lens focal length changes can make the human eye to see more than 1 'perspective of the object. But objects of different distances can not make a clear image on the retina at the same time. People pay attention to the object to see clearly, other objects on the distance blur, the distance between two objects
