Stop me if you've heard this one before. You're driving down an empty stretch of road, it's late at night, and you see traffic up ahead. You turn off your brights, but the approaching vehicles don't. After they pass, your vision is spotty and it's hard to see.
Everyone has dealt with this annoyance at some point. But the seemingly minor problem of bright lights shining in your eyes can damage the light-sensing cells that live in the back of your eyeball. These are called rods, the color-sensing cells are cones, and if exposed to enough bright light, the rods can become irreversibly damaged.
So a team of biohackers (yes, that's a real thing) has discovered how to give those light-sensing rods a boost: eyedrops. Yes, night vision eyedrops are a real thing now.
