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
2 reasons.
First is your pupils dilate, letting more light in.
Second is that “seeing” actually involves your eye using up its light sensitive chemicals. That’s why a bright flash can blind you for a moment, and why a bright light will leave a dark spot in your vision.
While you’re in a bright environment these chemicals are being used up fast. Especially your more sensitive rod cells, which because they are so sensitive get completely washed out in bright light. Once you move into a dark environment it might take several hours for your rod cells to completely refill themselves with those light sensitive chemicals and reach their full sensitivity.
