The procedure has allowed one superhuman to temporarily see over 50 meters (164 feet) in the dark, Mic reports. [/quote] [quote] First, Licina’s eyes were flushed clean and his eyelids were stretched out with a speculum (no blinking!). Then Tibbetts used a pipette to drop 50 microliters of a blackish solution—Ce6 mixed with saline, insulin, and dimethlysulfoxide (DMSO)—into his eyes. Specifically, he was aiming for the conjunctival sac, which should help carry the compound to the light-sensing retina. DMSO increased the permeability of the cells for better absorption. "To me, it was a quick, greenish-black blur across my vision, and then it dissolved into my eyes," Licina tells Mic. He then put protective lenses in his eyes to block out some light; sunglasses helped too. After two hours, the team tested Licinia's newfound superpower in a dark field. At first, Licina was able to see hand-sized shapes about 10 meters (33 feet) away. In time, he was able to recognize symbols (like numbers and letters) as well as objects moving against different backgrounds at longer distances. [/quote] Well that's kind of interesting
