I have a wifi router in my room and it has some LEDs, the instant I switch off the lights I almost can’t see anything but in a while the same room gets more visible.
It’s just an example and it happens to everyone, but how does it work? How do our eyes adjust to it, does our eyesight get better? The photons that reflect in our eyes would be the same right? Maybe our eyes (try to) create/sketch the room, based on how it gets the input?
How does this happen?
In: Physics
Pupils work like a camera’s aperture. In low light conditions, they dilate (get bigger) to let in more light, making it easier to see in the dark. When there’s lots of light, they get smaller to avoid letting in too much light which causes a few various problems.
There’s also some rod cell shenanigans going on, but the pupils are the main point.
