Participants were then told they were needed to help out with a different experiment, associated with physical acuity.(接着，参与者被告知他们需要在不同的试验中帮助别人，伴随着身体的敏锐度。)
Visual acuity indicates the angular size of the smallest detail a person's visual system can resolve.(视觉灵敏度指出了人类视觉系统所能分辨的最小细节角度。)
Vitrectomy may be indicated for severe hemorrhage and substantially diminished visual acuity, especially if it persists longer than 3 months.(当出血情况严重且使视力严重下降，特别是当其持续时间超过3个月时则须要行玻离体切割术。)
To help better educate our vision and visual acuity, carry a sketch pad with you always and take time to stop and draw.(为了更好的培养我们的眼光和敏锐的观察力，可以随身携带一本速写本，经常花上一点时间，静下心来画画。)
We don't lack visual acuity, but vision.(我们缺的不是敏锐，而是视野。)
Its high acuity allows you to see fine detail, such as the letters on this page.(只有它保持高灵敏性时，你才能看到细小的事物，例如现在这个页面上的字。)
Research by psychotherapist Elaine Aron bears out Guyer's hunch, demonstrating that withdrawn people typically have very high sensory acuity.(心理医生伊莱恩·阿伦(ElaineAron)的研究证实了盖伊的预感，研究显示，孤僻者通常有着很高的感觉敏锐度。)
Do the same for bad design. Soon, you'll be looking at graphics, interiors, and more with greater acuity.(看到非常差的设计时也照样做吧，不久，你看图形看设计的眼光将变得敏锐起来。)
Visual acuity was measured at the start of the study (baseline) and then monitored over one year (54 weeks).(在研究开始，所有人进行了视力测试，然后进行一年（54周）的观察。)
Common symptoms include reduced visual acuity, visual distortion (metamorphosia, macropsia and micropsia).(常见病征包括视力减退、影像扭曲（变形、变大或缩小）。)
