Imagine you could gain the ability to see in the dark using a special kind of eye drop.

It could be fun for anyone taking a night hike, and critically helpful for rescue teams or people working in dangerous environments at night.

Enhanced night vision might be more than a cool idea. An experiment performed a group of California biohackers shows it might be possible already — though they caution that they did this for research purposes and don’t know if the eyedrops they created are necessarily safe, especially in the long term. Something that allows more light into your eyes could cause cellular damage.

Don’t try this at home, in other words.
