有大量的研究提出，大熊猫具有发达的嗅觉和听觉系统但是视力很差。 虽然有些关于大熊猫视力和色觉方面的研究,但是至今我们对大熊猫的具体视力值方面的内容知之甚少。为了定量化大熊猫的视力值，我们观察并记录了8只圈养大熊猫（雌:雄=4:4）对于移动不同水平黑白相间条纹宽度的纸片的行为反应。我们发现，在测量距离为50 cm的情况下，大熊猫能够区分大约为0.46mm宽的黑白相间条纹。这个研究结果为大熊猫视网膜结构的解剖学研究提供了行为学支持，也为今后研究大熊猫的通讯和认知提供一定的参考。

A wealth of literature shows that the giant panda (Ailuropoda melanoleuca) has well-developed olfactory and auditory systems but poor eyesight. Although there are some studies of the visual ability and colour vision in the giant panda, little is known specifically about its eyesight. To quantify the giant panda’s visual acuity, we observed and recorded the behavioural responses of 8 captive giant pandas (M: F=4:4) to moving pieces of paper with horizontal black and white stripes of various width. We found that giant pandas are able to distinguish white stripes from black stripes at a distance of 50 cm when both were approximately 0.46 mm wide. This result provides additional behavioural support for anatomical studies of the retinal structure of the giant panda and will aid further studies of communication and cognition in this treasured animal species.
