双眼视觉，英文Binocular vision，是指生物在双眼视野范围互相重叠下，所产生的视觉。英文binocular的两个词根均来自于拉丁文，bini的意思是双，colulous的意思是眼睛。 其成因为双眼因具有瞳距，而在视网膜产生有差别但又基本相似的图像，这种视觉信号传送至大脑之后，大脑将两幅图像之间的差异进行集成，即可判断出眼睛到物体之间的精准距离关系。 与单眼视觉相比，双眼视觉有四个明显的好处：

双眼视觉通常伴随着视觉的融合，尽管两只眼睛中的图像并不相同，但是视觉在融合后可以产生单一的整体感觉。 其他与双眼视觉有关的现象包括utrocular discrimination，优势眼，双眼竞争。如果双眼视觉出了问题，可以寻求视轴矫正师医治。

Binocular vision is vision in which creatures having two eyes use them together. The word binocular comes from two Latin roots, bini for double, and oculus for eye. According to Fahle (1987), having two eyes confers six advantages over having one.

Other phenomena of binocular vision include utrocular discrimination (the ability to tell which of two eyes has been stimulated by light), eye dominance (the habit of using one eye when aiming something, even if both eyes are open), allelotropia (the averaging of the visual direction of objects viewed by each eye when both eyes are open), binocular fusion or singleness of vision (seeing one object with both eyes despite each eye's having its own image of the object), and binocular rivalry (seeing one eye's image alternating randomly with the other when each eye views images that are so different they cannot be fused).
