visual acuity

基本解释

However, resolving power is often compromised by atmospheric conditions and the visual acuity of the observer.
然而，分辨能力还与大气状况以及观察者的视觉敏锐度有关。
At those moments, our bodies actually take over and increase blood flow so that we have greater visual acuity, increased mental capacity and more oxygen and fuel for our muscles to use.
在那些时刻，其实是我们的身体掌握了主导权，血液加速我们的视觉更敏锐、脑力更强、提供给肌肉更多的氧气恶化能量。
