Fish have night vision
Biohacking: Night vision like a deep sea fish
In order to be able to see in the dark, night vision devices are usually used, which capture light in the infrared range. Night vision without a device is made possible by special eye drops developed by biohackers from California. Deep-sea fish are the model.

It is pitch black in the deep sea. Some inhabitants of this habitat can still see - thanks to chlorin e6 (Ce6). This substance improves eyesight in low light. The substance is otherwise used in cancer therapy. However, Ce6 for medical use is not obtained from deep-sea fish, but from algae.
Ce6 is trickled into the eye
The biohackers of the Californian group Science For The Masses have tested the night vision: Gabriel Licina had Ce6 dripped in his eye. To do this, Licina's eyelids were fixed with a special device to prevent blinking - according to Licina, that was the most uncomfortable part of the experiment.
His vision in the dark increased immensely: at night he could make out people in a forest at a distance of 50 meters. Even when they were standing in front of a tree, he could tell them apart from the trunk. For comparison, volunteers without Ce6 were tested. They found only about a third of the people in the wood.
However, night vision has one disadvantage: As long as the Ce6 was working, Licina had to wear black contact lenses and sunglasses inside. But not for long: the effect wears off relatively quickly. A dose of 50 microliters lasts a few hours.
