Episode 3: Vision and hearing protection
Miss Racoon: | Oh! You are sitting too close to play video games and the sound is too loud! These hurt your vision and hearing! We have to be aware of the different optimum viewing distance when using products with different screen sizes. About 30 cm for smartphones. About 40 cm for tablet PCs. About 50 cm for desktop computer and TV. Use 60-60 rule for the volume. That means listen not higher than 60% of the maximum volume, and no longer than 60 minutes a day. You've got it? |
Cobi : What? Are you talking to us?
