立体视觉是指视觉器官对客观的三维空间的知觉。换言之,也就是眼睛和视觉皮层辨别周围物体远近、深浅、凹凸、高低的能力。检查双眼立体视觉的仪器迄今为止,虽然有很多种,但限于条件,国内目前采用的多为Howard—Dolman氏距离识别器或同视机。前者比较古老,在临床上使用已有几十年的历史;后者价格昂贵,不便普及。因此研制一种准确可靠,简便易行的新器械,实属必 Stereo vision refers to the perception of the visual organ in the objective three-dimensional space. In other words, the ability of the eye and visual cortex to distinguish the distance, depth, bump, height of the surrounding objects. So far, there are many kinds of instruments for examining binocular stereoscopic vision. However, due to the limited conditions, most of the currently used domestically are the Howard-Dolman distance recognizers or the same viewers. The former is more ancient and has been in clinical use for several decades of history; the latter is expensive and inconvenient to popularize. Therefore, the development of an accurate and reliable, easy to use new equipment, it is necessary
