Well, there's a reason for that.

Your eyes have two main types of light-detecting cells called rods and cones.

Cones are mainly responsible for helping you see colours and fine details, but they need relatively brighter light to work well.

Rods, on the other hand, are much better at working in low light. The downside is that they don't give you the same detailed colour vision.

So when the lights go off, your eyes basically switch priorities.

Your brain is like:

“Forget the colours. We just need to see something.” 😭😂

That's why a red shirt, blue bag and green wall might all start looking like different shades of grey when the room gets very dark.

And here's another interesting part:

Your eyes don't instantly adjust to darkness. That's why when you enter a dark room, you might struggle to see anything at first.

But after a while, your vision gradually improves as your eyes become more sensitive to the available light.

So no, your eyes aren't suddenly becoming weak.

They're literally adjusting their settings. 😂

Quick fact: Rod cells help you see in dim light, while cone cells are mainly responsible for colour vision and work best in brighter conditions.
