Why Do Screens Make Us Feel Tired?

Screens make us feel tired because they give off a special kind of light called blue light. This light is like the sun, it can keep you awake, but if you stare at it too long in the dark, your eyes get sore and tired. It's like when you read a book in bed and your eyes are squinting all night.
