Shining Eyes

Individuals have evolved to have the tapetum lucidum (Latin for “shining layer”) layer within their eyes due to decades of time spent in darkness aboard the Patheon colony shuttle. The reflective layer creates the appearance of glowing at night. It is essentially a tiny mirror in the back of many types of nocturnal animals' eyeballs which helps vision at night. It is also what causes the glowing eye phenomenon known as “eyeshine.”
