Here are some recommendations regarding exposure to blue light .
Children have faster and longer access to screens: television, tablet, mobile phone ..
And adults tend to increase their exposure to blue light.
Here are three important recommendations:
- A digital curfew: no screens at least an hour before going to sleep
- Total darkness to sleep (without lights or night lights)
- The duration of exposure to natural light is a important factor in limiting the impact of exposure to screens in the evening
Some simple tips:
- No screens before age 3 and no more than one hour per day before age 12, children's eyes not being able to protect the eye as in adults,
- Exposing at least one hour to natural light every day
- Wear sunglasses in good weather, the largest source of blue light remains the sun
- Do not look at screens in the dark
- Every 20 minutes, look up from the screens for 20 seconds and set a point at 6 meters
- Do not look directly at the light sources and do not approach them at less than 30cm
