Let there be light! … Yes, but when it is blue? 

In its natural state, blue light is beneficial for health. In particular, it regulates our internal biological clock. It presents little risk to the eye. Its radiation is constant and relatively weak. And the eye has natural protections. In contrast, artificial blue light is toxic. It comes from screens like those of computers, smartphones, game consoles, televisions, and most of the lamps that light us up like low consumption lamps and LEDs. Artificial light generates light intensities up to 1000 times higher than the accepted visual comfort threshold [1] .

What are the dangers for health?

Artificial blue light causes eye fatigue, blurred vision, headaches, and difficulty concentrating. It also presents other significant health risks as it deceives the body. Our biological rhythm is indeed regulated by light. When our eyes perceive light, our brain releases arousal hormones. On the contrary, in the dark, sleep hormones are emitted to ensure that we fall asleep. Therefore, intense exposure to artificial blue light causes disruption in the body . This can lead to mood and sleep disturbances, or even states of depression.
