A group of biohackers has tested a special liquid by injecting into the eyeballs of a volunteer that provided him night vision. In the injection, the liquid used was Chlorin e6 (or Ce6), chlorophyll analog, which is found in deep-sea fish known for having light-amplifying properties. The liquid was put into volunteer biochemist Gabriel Licina's eyes.
Licina said, "To me, it was a quick, greenish-black blur across my vision, and then it dissolved into my eyes". The experiment was successful and then after an hour, he was taken out in a dark field. He was made to perform a number of performance tasks in order to tests his night-vision.
