复眼的空间分辨率由其小眼间角度、小眼的光学质量和横纹尺寸以及照明水平决定。在昆虫中，目间角度的变化范围从无翅目的数十度到蜻蜓的小至 0.24 度。由于衍射的限制，在实际尺寸的复眼中无法获得比这更好的分辨率。目间角越小，分辨物体（猎物、捕食者、树叶或花朵）的距离就越大。不同生活方式的昆虫具有不同的目间角度分布模式，与向前飞行、翅膀捕捉和水平表面捕食有关。
The spatial resolution of compound eyes is determined by their interommatidial angles, by the optical quality and rhabdom dimensions of the ommatidia, and by illumination level. Among insects, interommatidial angles vary from tens of degrees in Apterygota, to as little as 0.24 degrees in dragonflies. Resolution better than this is not attainable in compound eyes of realistic size, because of the limit imposed by diffraction. The smaller the interommatidial angle, the greater the distance at which objects-prey, predators, foliage, or flowers-can be resolved. insects with different lifestyles have contrasting patterns of interommatidial angle distribution, related to forward flight, capture on the wing, and predation on horizontal surfaces.
