Wilhelm Kühne's Glasses

Origin
Wilhelm Kühne was a German physiologist, known for coining the word "enzyme" and as a pioneer of optography, the process of receiving an image imprinted on the retina. The belief that the eye could "record" an image of the last thing it saw before death was widespread in the 19th and early 20th centuries, and was frequently used as a plot device in fiction, to the extent that police occasionally photographed the eyes of murder victims in case the theory was true.

Kühne was able to prove the extistence of such optograms through an experiment usig an albino rabbit whose head had been fixed facing towards a lit window for a time before it was beheaded and its eye dissected, providing an imprinted image of the window.

He was later able to study the existence of optograms in humans, which he was eager to prove, when a man was executed via guillotine for the murder of his children. The murderer's eyes were extracted and sent to Kühne for dissection and examination. However, Kühne was unable to adequately prove their occurance in humans due to the difference between human and animal eyes' anatomy.

Effects
When someone wears these glasses and makes eye-contact with a deceased person while concentrating, they will be able to experience the last 60 seconds before the victim died. They will be able to see, hear, feel, smell, and taste whatever they did - however, this proves a double-edged sword, as the wearer will also feel whatever the cause of death was.

While what the wearer feels cannot physically harm them, witnessing fatal events and feeling great pain or distress is commonly very traumatic for users. As such, use of this artifact for investigations is prohibited by the Regents.
