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?
