Blue light is a part of the spectrum of light, whose wavelengths are between 380 and 500 nanometers..
- The sun.
- LED bulbs.
- Screens (tablets, televisions, computers, smartphones).
The so-called dangerous blue light is a small part of all the existing blue light:
The energy reaching the retina in the case of the blue-violet light is stronger than in the case of the turquoise blue light.
The screens diffuse peaks of blue light called High Visible Energy (or HEV) light
Given the time spent in front of the screens, we are probably overexposed.
- In children under 14, the lens of the eye does not filter as well.
- In the elderly the negative wavelength is below 450.
- blue light can also have beneficial effects.
- It regulates our circadian rhythm (sleep / wake alternation) and our mood.
- The turquoise blue light (around 490 nm) which allows to recalibrate our rhythms during a jet lag.
- It regulates the production of melatonin, our "sleep hormone".
