Comfortable screen habits
- Top of the screen at or slightly below eye level, about an arm's length away.
- Stand up and move for a few minutes at least every hour.
- Blink often: we blink less when staring at screens, which can dry the eyes.
- Get your eyes tested regularly, and see an optician if you have headaches or blurry vision.
