How Does Dark and Light adaptation Work?

When you go from a bright place to a dark one, your eyes need time to adjust, that’s dark adaptation; and when you go back, it's light adaptation, like switching between day and night!

Imagine your eyes are like a flashlight. When it's bright outside, the flashlight is on full power, you can see everything clearly. But when you go into the dark, like from a sunny playground to a dimly lit room, the flashlight needs to turn down so you can see in the dark. This takes time, maybe a few minutes, because your eyes are getting used to less light.

Now imagine coming back from the dark into the bright light. It's like turning on a really strong flashlight suddenly! Your eyes need a moment to adjust, so things don’t look too bright or blurry. You might squint at first, that’s your eyes working hard to get used to more light again.

So whether you're playing hide-and-seek in the dark or reading under the sun, your eyes are busy adjusting all the time!
