Why Can't You See Through Your Phone Screen at Night?

Your phone screen is like a tiny lamp. When it’s dark, the lamp isn’t bright enough to help you see clearly. It’s kind of like trying to read in a room with only one small lightbulb, your eyes get tired and everything looks blurry. That’s why turning up the brightness helps you see better at night.
