What does seeing mean with respect to different living beings? Is seeing with a compound eye similar to seeing with a single-lens eye? In what way is vision conceptually coupled with the formation of a retinal image? These and other questions arise from consideration of a famous photograph of the retinal image formed by the eye of a glowworm in Sigmund Exner’s authoritative treatise on compound eyes of 1892.

萤火虫能看见吗？

看到对不同的生物意味着什么？用复眼看与单眼看相似吗？视觉在概念上与视网膜图像的形成有什么联系？这些问题和其他问题源于Sigmund Exner在1892年关于复眼的权威论文中对萤火虫的眼睛形成的著名视网膜图像的研究。
