The centre of our visual field (the fovea) has the highest ability to resolve fine details (acuity), and if we notice something of interest in our surroundings we will move our eyes so that the image of the object falls on the fovea, rather than some peripheral part of our retinas. We do this because our visual systems have low acuity away from the fovea. If is often surprising how few letters on a page we are able to identify as their distance from the fovea (eccentricity) increases.

我们视野的中心（中央凹）具有最高的分辨细节（敏锐度）的能力，如果我们注意到周围有什么感兴趣的东西，我们会移动眼睛，使物体的图像福尔斯在中央凹上，而不是我们视网膜的外围部分。我们这样做是因为我们的视觉系统在远离中央凹的地方敏锐度很低。如果经常是令人惊讶的是，我们能够识别的字母很少，因为它们与中央凹的距离（偏心率）增加。
