When you stare at a screen for too long, your eyes get tired. It's like when you look at something really close, your eyes have to work extra hard! Screens are also brighter than normal things, so your eyes feel like they're working in the sun all day. This makes them hurt and feel tired.
Examples
- Looking at your phone during lunch makes your eyes feel like they're working out.
- Reading on a tablet after school feels like staring at the sun all day.
- Staring at the computer for hours makes your eyes look like they’re tired from running a marathon.
